Franklin Electric submersible motors are water lubricated. Utilizing technology securely and successfully means having the capacity to control it. For heavier equipment, the electronics are usually concentrated in one place: The control box. Building a high-performance control cabinet means knowing the details required for a specific application, as well as general control cabinet design best practices. 
Before we get started, however, let's lay out a basic standard for what a control box is and what most people want from a control box, and quickly review the basics of the control box design. These topics will familiarize you with key concepts while exploring the best ways to build and design control boxes. Since control boxes are used for many different types of equipment, it is difficult to define their basic definitions, but there are certainly some common characteristics. A basic classification of key functions and components of an electrical control box includes: The control box provides the operator with a physical interface to control the equipment and monitor its performance. Control boxes usually contain various instruments such as switches, knobs, sliders, and buttons. These are connected to the device and used to control it, allowing the operator to start, stop or adjust various functions. The control box also usually contains instruments that provide sensor data. This data is used to ensure that machines are working properly and allows operators to use automation to make control decisions or create rules and procedures. The actual connection between control and equipment usually consists of relays, timers, and programmable logic controllers (PLCs). 
Controls are usually located in electrical boxes to prevent accidental contact, unauthorized access, or damage to the controls. Many newer control box designs also use touchscreens to provide operators with intuitive and precise control over the process they are using. You'll find control boxes in nearly every industry in the world, from those controlling heavy industrial equipment to those used for DIY projects. Each type of control box has its own requirements and characteristics, and each requires careful attention to design best practices. The filling solution consists of a mixture of deionized water and propylene glycol, a non-toxic antifreeze. This solution protects against freezing temperatures down to -40°C. The motor should be stored in an area no lower than this temperature. When you own a house with a well, problems can arise unexpectedly. Fortunately, there are steps you can take to ensure that your well water system has few or no problems. 
A nice, sturdy well pump control box will allow you to enjoy the convenience of fetching water and avoid many of the hassles and costs associated with poor-quality pumps. The well pump control box is essentially the brain of the water system as it handles many tasks to keep the system running smoothly. The pump control box is responsible for monitoring the water flow and controlling the water pump to maintain it at the desired level. Pump controls may vary depending on the type of control box installed. They are also responsible for protecting the pump from possible low and high pressures such as short circuits and overloads. Here are some specific things the control box can do: Alternately operate the pumps. Change the speed of the motor to avoid low water pressure. Protects the motor from wrong voltage and water tank flooding. Start the high voltage motor. Detects water flow and level and signals the device to turn on/off. 
Check pumps, such as those supplying chemicals. If necessary, start the well pump generator. Shut off the well pump when the water level is too low. Open and close the valve. Displays the time the pump was on. Choosing a control box depends on different factors. Price is an important factor when choosing a control box, as there are many cheap but also flawed. Manufacturers often use inferior components in inexpensive control boxes, which can lead to unnecessary well pump repairs. It's also important to make sure you're buying a control box with the features you need, not one that will drive up the price with unnecessary features. Well, box installers often carry a multi-function box with them so they can install one on any job site. This sometimes leads consumers to pay more for things they don't need. 
There are many affordable control boxes you can buy to suit your needs, but watch out for what you don't need as the price tag will be higher. Supply voltage and motor amperage are the other affecting factors in the choice. You need to know the supply voltage of your water system in order to determine which well box to use. The control box voltage has to coordinate with the pump voltage. It's best to determine what type of pump you will be using, then compare the voltage and current to the ratings of the control box. Also, the control box itself is considered a factor in choosing. There are several control types used to control the pump: Float switch that rises and falls with the liquid level. Then, the Sensor measures the weight of the water. Also, Pressure Bell Increases the pressure inside the bell as the water level rises. Decide how you want to control the pump so you can choose a control box that is compatible with your desired selection. The control box contains the starting circuit for the well pump. 
The control box is mounted on the outside near the well. The advantage of a three-wire submersible well pump control box is that if one component fails, you can easily replace the individual parts without removing the pump itself from the well. This means your submersible well pump has lower maintenance costs and a longer lifespan.
Submersible electric motor
A submersible pump is composed of different components such as a motor and pump. The submersible well pump is located underground, completely in the tank. It relies on pressurized water rather than suction to move the water to the surface. A pump delivers excess water to a well pressure tank above ground, which is usually part of your home's plumbing system. The pump runs when completely covered with water. Turbines move the water into a surface storage tank, which then enters the home plumbing system and adjusts access to the well via an adapter. 
There are different types of submersible electric motors with two types of cooling methods. Surface cooled and forced cooled. Both sorts can be given for immersible (IP67) or submersible (IP68) operation. For continuous diving operation or just diving, a wide range of surface-cooled motors is offered. Typical applications for these motors are dredging pumps, deep well pumps, and sewage pumps. Electric motors have been developed with forced cooling for immersion or submersible applications. Typically, motors must reach their rated power when running dry or underwater. Other features of this design are the very low airborne noise produced by these types of motors and the lack of heat dissipation to the direct environment, which can be critical in some applications. Unlike jet pumps, submersible pumps do not have a pressure tank. It includes a pump motor, an internal check valve, and a water pump. 
The main difference between a jet pump and a submersible pump is that the latter pushes the water up while the jet pump pulls. Less energy is required to push, so submersible pumps are better suited for deep wells. You can decide which type you want based on the depth of the well. Generally, 25 feet is considered shallow. If it's 25 to 400 feet long, a submersible pump might be the best option. You can view drilling reports for accurate measurement information. Submersible pumps are installed underground and can pump water to a depth of 325 feet. You also get great versatility and value with our submersible well pumps. Our submersible pumps are available in 1/2, ¾, and 1 HP, these pumps can provide up to 26 GPM of water for small to mid-sized homes. These pumps are wired for 115 or 230 volts 2-wire or 3-wire (plus ground). 3-wire pumps need a control box (purchased separately) to function. 
Heavy-duty pump housing includes a 1-1/4" drain and safety line eyelet for lowering the pump into the well. Includes instructions and a handy quick start guide for easy setup and use. 100% factory tested. When you choose a submersible pump, you get many benefits, including They thrive in any climate, including mountainous or dry. They work deep. They are self-sufficient, which speeds up the process. They use less energy because less energy is required to run submersible pumps because they rely on thrust and gravity to move water. They require little maintenance. They persist for decades as long as the sediment levels in the water are low. Our company develops and manufactures submersible motors for a variety of applications in water, mining, and offshore. Equipped with special cooling technology (MCT) and internal permanent magnet motor technology (IPM), our submersible motors achieve impressive performance, efficiency, and cost savings. 
Its rewindable winding makes some of our submersible motors ideal drivers for deep well submersible pumps, bottom intake pumps, seawater lift pumps, and subsea machinery. Therefore, they can be used in water supply and offshore as well as in the mining industry. They are designed as water-filled, water-cooled three-phase asynchronous motors with squirrel-cage rotors and mechanical shaft seals. Depending on the area of use, these submersible motors can be made of cast iron, bronze, or stainless steel and can be installed vertically and horizontally. For more information on our submersible motors, please contact us directly. Efficient and cost-effective cooling of submersible motors is a constant topic of discussion among well and mine operators. Derating is a less than ideal solution. In addition to high capital and energy costs, oversized and derated motors often require larger shaft diameters. Particular attention must also be paid to oil cooling - any failure can lead to ecological damage. 
Our motors are equipped with the innovative Modular Cooling Technology (MCT), which increases durability and is the most efficient way to cool submersible motors. The absolutely maintenance-free motors use potable water as the cooling medium and can be installed in fluids up to 75°C. The pump impeller brings motion into the cooling circuit, providing flow in the correct direction. Our self-developed cooling channels ensure heat absorption and dissipation from all heat sources, as well as optimal heat transfer through the outside of the engine to the flowing medium. The extra utilization of heat exchanger modules permits precise dimensioning of the cooling capacity. This type of motor has some advantages including Reducing investment and energy costs, drinking water as a cooling medium, being suitable for moderate temperatures up to 75°C, maximum operational reliability, and extremely long life. Internal Permanent Magnet Motor (IPM) technology uses a rotor with embedded permanent magnets. Existing asynchronous motors thus become permanent-magnet synchronous motors with an impressive performance: average efficiency increases by 4% and in the partial load ranges, as much as 7% higher at levels above 90%. 
When it comes to flexibility, IPM motors are the perfect complement to our Modular Shaft Pump Technology (MST). Due to the simple assembly and disassembly of the modules of the MST stage, the delivery pressure of the pump can be flexibly adjusted to suit the respective operating conditions. This motor technology provides you with the following advantages: Efficiency increases by up to 100% for the same size, a wide range of applications reduces storage and logistics costs, and extremely high efficiency down to the part-load operating range guarantees the lowest energy costs. And high efficiency and excellent power factor go hand in hand with low power consumption. So smaller cable segments can be used, and flexibility to adapt pump performance to duty point with lossless frequency converter. Our company is a family business and we love doing business with you. Our products are known for their exceptional craftsmanship and reliability. We also provide excellent customer service to help you every day.

Franklin electric submersible motor
As it is mentioned earlier, Franklin Electric is a manufacturer that produces different fluid positioning equipment such as submersible motors, control boxes, different pumps, and other accessories to name a few. The submersible motor design allows the safe operation of water and wastewater applications. Protective structures, sealing, and monitoring contribute to the motor’s ability to operate in and underwater. A fundamental electrical safety rule is that water and power don't blend. In any case, alternating current (AC) induction engines must operate submerged or underwater in order to operate pumps, mixers, and aerators in industrial water and wastewater applications. Submersible motors must be specially designed and manufactured to prevent water from coming into contact with any part of the circuit while providing a long service life in these harsh applications. Submersible motors are completely enclosed and non-ventilated. It has no external shaft-mounted fans to cool and dissipate heat from the frame. 
In wet pit applications, it relies on the liquid submerged in it to dissipate heat from the frame. Its duty cycle is continuous in water and has a capacity of 15 minutes in the air. In dry pit applications, the motor can operate in the air and underwater for extended periods of time. Since air doesn't dissipate heat as liquid does, it is often necessary to oversize the chassis to allow more surface area to carry heat away from the motor. The potential presence of flammable gases or liquids and combustible dust can also affect the design of motors operating in water and wastewater applications. Methane gas is formed by the decomposition of solids. It is potentially explosive when present all or part of the time and may require Division 1, Class I, and Group D certification of the engine. It is the user's responsibility to specify the engine hazardous area certification requirements. They can refer to the National Electrical Code (NEC) National Fire Protection Association (NFPA) 70, which defines hazard classes for spaces or enclosures. 
They can also refer to the Standard for Fire Protection in Wastewater Treatment and Collection Facilities (NFPA 820), which defines the hazards and classifications of treatment areas. Submersible motors are designed and manufactured to prevent water from entering any part of the electrical components while providing a long service life in submersible applications. Some may wonder why the motor should work with gas submerged on top of a liquid. The reason has to do with the 15-minute, in-air duty cycle capability. Since the motor may operate in the air under abnormal conditions, it must be properly certified for hazardous environments. A heavy-duty cast-iron frame should be used when constructing a submersible motor. Cast iron provides good protection in industrial environments because it is not prone to denting, deflecting, or bending, which can cause the waterproof enclosure to fail. The frame is precision machined for a tight fit between parts. All machined fits have a groove and O-ring to keep water out of the motor. 
A non-wicking cable cap secures and seals the power cord to the frame. The power wires going in and out of the cap are separated by a butt splice, and then the entire cap is filled with epoxy rubber gaskets to seal. Cable cover seals must be strong, as the cables can bend in multiple directions during transport and motor installation. Never use a rope to pull or lift the motor as this may cause the seal to fail and allow water to enter the motor. Type 21 mechanical shaft seals are often used in submersible motors. This versatile seal rotates with the shaft against a fixed mating surface and uses a mechanical crimp part to eliminate adhesive. To securely seal the output shaft and protect the motor, the submersible motor has an inner and outer seal on the drive end plate. The drive side plate of a submersible motor is different from that of a standard induction motor. The drive end plate of the submersible motor is hollow and designed to accommodate the oil chamber and humidity probe. Internal seals are installed in the oil cavity where the shaft enters the stator frame and are kept lubricated by the oil in this cavity. 
The outer seal is mounted on the outside of the end plate, where the shaft leaves the frame and connects to the pump. It is greased up by the pumped fluid. The outer seal must withstand surface wear on its outer surface from contact with the pumped liquid. The higher the viscosity of the fluid, the greater the wear. Type 21 seals are available in a variety of stock materials to meet specific operating conditions. Pump manufacturers typically specify the seal material that is best for the pumping application and provides the longest seal life. Typical Type 21 seal materials include: Carbon ceramic face seals are general purpose stainless steel seals typically used in food processing, petrochemical, and wastewater applications with relatively clean effluents. Tungsten carbide face seals are a popular type that provides a harder seal face for more demanding applications in more viscous fluids. 
Silicon carbide face seals are typically used in the most demanding slurry-type applications (high viscosity fluids). The monitor is the last topic. Regardless of the material of construction, washers are wear devices. Surface wear on the outer seals can cause the seals to fail, allowing fluid to enter the engine. In this case, oil chambers and humidity sensors provide critical safety features that extend engine life. The probe adjusts according to the resistivity of the oil filling the chamber. If the outer seal fails and water mixes with oil, the humidity sensor detects the ingress of moisture and sends a signal to the panel warning alarm control through the control module. This gives the user time to stop the pump, replace the outer seal and restart the motor. Submersible motors are different from other induction motors. They are designed to operate safely and underwater. Its robust construction, secure sealing, and protective safety monitoring ensure the long life and safe operation of pump equipment. 
Franklin electric submersible motor control
The submersible motor is one of the Franklin Electric products that regarding the developing technology, the user can control from the ground. The main task of the well pump electrical control box is to open and close the pressure switch of the pump. In a private well system, a pump draws water from the ground and pumps it into a pressure tank. The pressurization within the tank then provides the force that enables the building to get tap water. When the pressure in the tank drops below a certain level, the pump cycles on and off to continuously reach and maintain acceptable levels. At the heart of the entire process is a pump control box. We recommend that you speak with one of our professional plumbers to determine which type of well pump control box is right for your pump. A well pump controllers typically have microprocessors that monitor the power consumption of power line pumps and tension motors. A well pump control box is essential as it protects submersible well pumps from Voltage too high or too low, blocked well screen, Defective motor, and pump, water level drop, ride fast, and low production well. 
Every electric motor, regardless of size and purpose, requires some kind of control mechanism. Simple motors, such as the drill and sander in the average garage, the hair dryer in the bathroom, or the mixers and food processors in many kitchens, only include a simple switch to turn the motor on and off. Other motors, such as those in welding robots, 3D printers, and CNC (Computer Numerical Control) machines, require more sophisticated motor control. Before we dive into the different types of motor controllers and drives, let's first understand what a motor is at the most basic level. A motor is an inductor, and if you think about it, the current flowing through the inductor doesn't change instantaneously. For example, if current flows through an inductor and the switch is flipped to "stop" that current flow, rest assured that the current will continue to flow and the associated voltage will rise very quickly (i.e., immediately). The MIT Department of Physics has demonstrated this concept nicely by "turning off" the current flowing through a set of solenoids. Remember that solenoids, like motors, are also inductive. Therefore, since it is not possible to immediately stop the current flowing through the motor, no sparks or smoke. 
The motor controller and driver must provide means to allow the motor current to be safely directed and controlled, which may slowly dissipate after the engine is turned off. Diodes are perfect for this classification task. Hall-effect sensors work by sensing the magnetic field produced by a magnet or current, allowing them to detect the speed, position, and orientation of a motor and operate continuously in harsh environmental conditions. Hall effect sensors improve the robustness and repeatability of motor control systems compared to mechanical control sensors that can be damaged in very dusty and wet environments. Another method of position feedback involves detecting voltage spikes that occur whenever power to the coil is momentarily removed. This control method is often referred to as a "sensorless" control method. Stepper motors, such as servo motors, are also used in complex motor applications. Unlike servo motors, however, stepper motors typically do not use a closed-loop feedback system, but rather an open-loop feedback system, where the position of the motor rotor is assumed to follow a controlled rotating field. This open-loop motor control provides precise positioning in a simpler and less expensive control system than closed-loop control schemes. 
Many motors control circuits, even the simplest, include some motor overload protection features such as overcurrent, temperature sensors, and voltage monitoring. Many motors are controlled or driven by computer control systems, solid-state logic controls, or programmable logic controllers (PLCs). Programmable logic controllers and other solid-state control devices were originally invented to provide cheaper alternatives to older automation systems that used numerous mechanical relays and timers. In some cases, a single PLC can replace thousands of relays, reducing the cost of the wiring system and providing greater flexibility in control design. Devices such as solid-state sensors, solid-state drives, solid-state relays, and programmable controllers can provide very precise control of industrial processes. The requirements of each motor control system are unique. The accuracy with which the motor must be controlled depends on these system requirements. For example, industrial robotics requires very high precision in motor control so that welding robots can operate at high speed and high precision. 
High-precision motor control systems require a robust and reliable information path from the sensor to the controller. Note that this basic data is regularly communicated utilizing long cables. Additionally, many manufacturing plants have inherently high levels of EMI (electromagnetic interference), which explains the use of differential signaling in high-precision motor control systems. Incremental data is more often than not transmitted to the controller through quadrature signals, i.e., two signals that are 90° out of phase. These signals can be in analog shape (sine + cosine) or in binary form. Absolute position information, on the other hand, is only via RS- 482 or RS-422 serial binary data stream. Electric motors are ubiquitous in modern society, from the power tools in our homes and kitchens to the cars we drive (including gasoline, hybrid, and fully electric vehicles). And the manufacturing facilities that make our smartphones. While some motors are very simple and some are very complex, they all have one thing in common: they all require motor control. 
Some motor applications, such as hair dryers, require only a simple motor control scheme, such as a switch to turn the motor on and off. Other motor applications require sophisticated motor control to provide high precision and high-speed motor control operations, such as those found in our modern manufacturing facilities. Motor control is another powerful but oft-overlooked technological marvel that has evolved over time to make our modern lives so much easier. There are four main types of common motor controllers and drive types in industries. The first type is AC. An AC motor controller and driver is an electronic device that changes the input power of the motor, usually by adjusting the frequency of the motor power, to regulate the output speed and torque. Key specifications include intended application, drive operating mode, motor type, inverter type, loop system voltage classification, power rating, communication interface, and input and output electrical specifications. AC engine controllers and drives are primarily utilized in preparing applications to control the speed of pumps, fans, blowers, etc. 
They are called variable speed drives, variable frequency drives, or AC inverters. The controller is usually integrated into the driver circuit and provides control signals to the driver. The next model is the DC motor controller and drive type. DC motor controllers and dimmers are electrical devices that vary input power by adjusting a constant or AC power source to a pulsating DC output with different pulse durations or frequencies. Key specifications include the intended application, drive operating mode, motor type, circuit system, voltage classification, power rating, output signal type, communication interface, and input and output electrical specifications. DC motor controllers and drivers are mainly used to control the speed and torque of motors such as machine tools, electric vehicles, and pumps. A controller, usually integrated with the control circuitry, provides control signals to the driver. The next type is servo motor controllers and drives which are electronic devices that vary input power by adjusting a constant or AC power source to a pulsating current output with different pulse durations or frequencies. Key specifications include the intended application, motor type, drive operating mode, loop system, power rating, output signal type, communication interface, and electrical specifications. 
Servo motor controllers and drives are primarily used in motion control applications such as manufacturing and construction environments to control motor speed, torque, and position, and can be AC or DC powered. Servo motors are used in many applications including machine tools, micro-positioning, and robotics, as well as many other types of machinery such as conveyor belts or spindle drives. The controller is usually integrated into the driver circuit and provides control signals to the driver. Servo motors are also called servo motor amplifiers. The last type is stepper motor drivers and controllers which are electronic devices that vary input power by adjusting a constant or AC current source to a pulsed or "stepped" current output. Key specifications include the intended application, motor type, drive operating mode, loop system, power rating, output signal type, communication interface, and electrical specifications. Stepper motor controllers and drivers are mainly used in motion control applications such as manufacturing and construction environments to control the speed, torque, and position of the motor. They are used in many applications including machine tools, micro-positioning, and robotics, as well as many other types of machinery such as conveyors or OEM equipment. 
The controller is usually integrated with the driver circuit and provides control signals to the driver. Stepper motors are also known as pulse motors and stepper amplifiers. Stepper controllers are also known as motor indexers. As a family-owned business, our company has always put the needs of its customers first.

1 hp submersible electric motor
Since we have gotten acquainted with the characteristics of a submersible pump, this machine works with an electric motor that can produce 1 hp power and more. A submersible pump can be 2 wire or 3 wire. The main difference between 2-wire and 3-wire well pumps is the location of the motor starter assembly. Three-wire well pumps house starting components (start capacitors, run capacitors, relays, and thermal overload) in an enclosure or control panel. The control box is usually mounted on the wall above the floor. Components can be easily accessed and repaired or replaced at a lower cost, although the probability of parts failure is greater than in a two-wire system. For example, if a three-wire capacitor fails, only the capacitor itself needs to be replaced. On the other hand, two-wire well pumps do not use a control box. All elements are integrated into the engine or pumping station itself. This makes installation easier. However, if any of the starter components fail, the pump will need to be pulled up and the entire motor replaced. 
The probability of component failure in a two-wire system is much lower than in a three-wire system, although if a part fails, it will be a more expensive and time-consuming job. Ultimately, it's up to you to decide which method works best for your application. Your situation may dictate one configuration over another. Keep in mind that motors over 1.5 HP require a three-wire setup and a control box to start heavier motors. For any type of electric deep well pump, the main differences in wiring will depend on the wattage of the motor running on the pump and the location of the starting components on the pump such as relays and starting capacitors. Without going into too much engineering and physics, just know that the three-wire configuration is used for well pumps that require more horsepower to start and require a motor in excess of 1.5 HP (horsepower). All well pumps will have a ground wire, but the ground wire does not count when distinguishing between the two types of well pumps. 2-wire well pump with Ground Wires In the way a 2-wire well pump is configured, the motors will be connected by two black wires and a green ground wire. The starter assembly will be inside the motor itself, which will be more difficult after installation if you need to inspect or service the pump. 
In this case, you will need to remove the pump from its mounting location for inspection. But since everything is built into the pump body, installation is also easier and faster. Two-line pumps are also less likely to fail due to the way they are constructed and have fewer overall components. However, if something goes wrong, it is much more expensive to repair or replace them. In a 3-wire well pump configuration, the motors are connected by black, red, yellow, and green (ground) wires. Three-wire pumps use a separate control box external to the pump that houses the critical start-up components, which are usually mounted on a nearby wall above the floor. This makes installation more labor-intensive, but if something goes wrong, it is easier and cheaper to repair and replace individual parts rather than the entire engine. While 3-wire pump units do have more parts and are therefore more likely to require service and maintenance, a separate control box allows easier access to major components without removing the well pump from its installation location. Also, because there are more parts in a 3-wire system, repairs may be cheaper and faster, as the system may only have one part to repair, while the motor assembly in a 2-wire pump needs to be replaced. 
By mentioning the characteristic of 2-wire and 3-wire submersible pumps, this question will be proposed which one is better? In short, if you need a deep well pump with more than 1.5 hp of motor power, your safest bet is to use a 3-wire well pump to get it up and running. If your application does not require such a large well pump, some purchasing decisions will need to be made. Would you like to maintain the pump starter assembly with ease and replace only damaged parts? Want to avoid taking the pump out of the pond for inspection? If so, choose a 3-wire well pump. The starting price for a three-wire pump may be higher, but you will pay for the replacement of individual parts of the pump as well as the long life of the pump itself. If you want a cheaper starting price, quick and easy installation, and the ability to replace the entire pump in the event of a major problem, an all-in-one 2-wire well pump might be the way to go. The right choice for you. 
It goes without saying, but before you try to install or replace a well pump, make sure you know what you're doing or call a professional instead. Electricity is dangerous and incorrect wiring can damage the pump. Whether you're doing the work or not, it's important to know the type of well pump you currently have in order to choose the right replacement pump. If this is your first installation, you need to know what the correct pump is for you to make sure everything works. 30 to 40 years ago, many installers installed 2-wire pumps without a ground wire. If you are replacing a current pump with only 2 wires, you must run the ground wire for the new pump. Many customers ask us if I can replace a 3-wire pump with a 2-wire pump? Technically yes, but to do this you need to install a tech cap on the third wire that won't work with the new pump. However, to change from a 2-wire pump to a 3-wire pump, a new third wire needs to be installed, and a control box needs to be installed to make the correct connections. Your owner's manual should include a well pump wiring diagram describing the wiring and connections in your setup. This is called a wiring diagram, and you can usually find it in your existing control panel as well (if it exists). 
From the manual/schedule, you will be able to determine if the current well pump is a 2-wire or 3-wire pump. Consult your circuit breaker panel to find out your pump voltage and determine if it is a 110V, 115V, 220V, or 230V configuration. We have recognized the need for a reliable well pump control box solution. We offer state-of-the-art features, designs, and materials in electronic enclosures. Additionally, we test all of our well pumps and well pump controllers for the highest quality performance. In case you need a submersible well control box, our specialists can help.

Submersible dc electric motor
DC submersible pumps, as well as other types of submersible pumps, look like metal tubes, and their purpose is to push water to the surface. This tubular water pump hides the electric motor inside the tube so that the liquid outside the pump cannot reach the electrical components inside the pump. 
DC submersible pumps are versatile and can better adapt to different working environments because they can be powered by various independent DC power sources. The most common power sources for DC submersible pumps are solar modules, batteries, or generators. Solar DC submersible pumps sometimes have a controller that improves the current when the sun is low. Typically, DC submersible pumps can operate on several volts of DC, such as 6V, 12V, 24V, or 32V. There are certain advantages to applying direct current instead of alternating current (AC). The first advantage is that the DC power system allows the submersible pump to accommodate more power options, such as batteries. It makes the machine portable and the application more convenient. Also, AC power systems require a controller to control the speed, while AC power systems do not require such a device. In most cases, a power system controller is only required when applying solar modules. DC submersible pumps are also more energy-efficient. 
Less energy is required to operate a DC submersible pump than an AC model. However, DC motors also have limitations. The service life of DC submersible pumps is shorter than that of AC submersible pumps. Also, while DC motors are more energy-efficient and easier to use without a current controller, they tend to run at considerably lower speeds and are less powerful in pumping. Submersible pumps are used in many fields. For example, they can be used to pump sewage out of septic tanks, which is convenient because pumps deliver sewage directly into the septic tank so that it can be transferred to a treatment facility and treated later. Second, they can be used in industry as well as in construction. When a construction site has too much unwanted water or the basement of a building is flooded, a submersible pump can be used to easily pump all the water from the place. Another common use for submersible pumps is in oil wells. Whether it's an inland or offshore well, submersible pumps can pull oil from the surface and deliver it to a factory for further processing. 
Certain types of submersible pumps can also be used to drill wells to a certain depth. They are called drilling pumps or borehole pumps. In addition to industrial use, submersible pumps can also be used in agriculture as part of an irrigation system. The main use of submersible pumps is to pump liquids from above or below the surface. Submersible pumps are best for the job because of several reasons. On the one hand, a submersible pump keeps almost everything inside the tubular body. Therefore, it doesn't take up much space. In other words, submersible pumps work better in closed environments than other types of pumps. Submersible pumps are connected directly to the tank by hoses or pipes, which also take up very little space. Therefore, they adapt to most possible work environments. Another quality of submersible pumps, again derived from design, is that they are the safest choice of all other types of pumps. 
Since all working parts of the machine are contained within the fuselage and the entire body will be in the pit at the job site, there is little chance of injury to surrounding users while the machine is running. This feature alone makes submersible pumps stand out and gain widespread acceptance. Also, since all the components are carried inside the pump and run underwater in most cases, they don't make a lot of noise. Or to be more precise, the noise made by the machine during operation is blocked by the water and the casing of the machine. Additionally, the simplicity of the mechanism makes this type of water pump more efficient when pumping liquids from basements. In addition to the safety, efficiency, and quietness of the submersible pump, the maintenance of the machine is also quite easy. Indeed, it does not require much maintenance, as the working parts and electrical components are protected within the machine casing, and small contaminants are less likely to enter the body and damage the machine. Also, since submersible pumps work in water, they are water-cooled while working, and the machine can last longer with this mode of operation. 
The application of DC submersible pumps is mainly in so-called dewatering operations, and their use has many advantages due to the design and power source of their operation. The main advantages of DC submersible pumps are convenience and ease of use, as the pump mechanism is simple and the power system allows for greater portability of the machine. If users are looking for a reliable and compact water pump with multiple power options, a DC submersible pump may be the right choice for them. Running A DC pump on AC is still a hotly-debated topic for many customers. The short answer is yes, most solar pumps can be reconfigured to run on a 240V/AC source such as a generator. Some solar pumps have a built-in controller and can be powered by DC (solar panel) and 240 VAC power. The power cord for these solar water pumps consists of 2 wires and 1 ground wire. Most small brushless DC solar pumps operate on lower voltages such as 12V, 24V, 36V, 48V, or 96V. These types of solar pumps require an external control box that converts the DC voltage to the motor's pulsed voltage via a three-wire power cord. 
The motor power cord must consist of three wires of the same gauge, excluding the ground wire. If using 240V/AC power to run these solar pumps, these low voltage pumps require an AC/DC converter to convert the 240V/AC to 24V, 48V, or 96V/DC. The 36/48V DC pump can also be powered in battery mode when the solar panel is not used to run the pump. Simply switch to battery mode inside the controller and connect the battery to enough power to run the pump.
Submersible 12 volt electric motors
A 12-volt electric motor is one of the most common motors used in submersible pumps. We all use batteries in our daily life. Whether in our remotes, watches, cars, or RVs, batteries are part of our lives. Most of the time, we don't need to consider the voltage of the battery. However, when using a DC power system for RV or off-grid applications, careful decisions must be made between 12V and 24V. 
Most cars, RVs, and boats use 12-volt electrical systems. To learn more about batteries, we first need to understand what a volt or voltage is. Voltage is the amount of electrical pressure required to drive current. 12V tells us that the battery provides 12 volts under nominal load. The same principle applies to a 24V battery pack, which provides 24 volts. As we discussed earlier, most car and RV batteries are 12V. Most vehicles use 12V batteries because electrical components such as starters, lighting, and ignition systems are designed to run on 12V. The battery's 12-volt rating is the nominal voltage, which can be slightly higher or lower depending on the state of charge and load. We sometimes use 24V battery systems in larger trucks and buses due to higher vehicle power requirements and longer cables. You may also see 24V used for larger boats and some RVs with sophisticated solar systems. Another typical application for 24V systems is trolling motors for fishing boats. 
A 24V system is where 24V is output at rated load. There are several ways to create a 24V power system. One solution is to buy a 24V battery. The other is to use two 12V batteries in series to form a 24V system. Let's look at these options in more detail. One way to create a 24V system is to use a 24V battery. 24V batteries are not as common as 12V batteries and are more difficult to find. 24V batteries are also more expensive. However, they take up less space than other series batteries. So, if space is an issue, a single 24V battery might be your better option. 12 volts is the most commonly used voltage measurement for small motor applications. For extremely heavy motor applications, a larger voltage, such as 24 volts, may be required. Voltage is also commonly referred to as potential energy, which is defined as the energy required to move a unit charge to a specific point in a static or stationary electric field. 
As a standard voltmeter, 12 V motors are commonly used in a variety of applications and industries, such as industrial manufacturing, for powering small factory automation equipment. Residential, for DIY tools such as sanders and drills, and for household appliances such as mixers and dishwashers Appliances to power. Transportation, to power small vehicles such as scooters and bicycles. And electronics, to power small electronic devices such as lighters and sirens. Although all-electric motors provide the same basic function of converting electrical energy into mechanical energy, the way they convert energy can vary widely. Also, 12v motors are not classified by the method they convert energy, but by the amount of electricity used to convert energy. Therefore, a 12V motor can encompass many different types of motors, rather than specifically referring to a single design or type of motor. Most commonly, 12V motors are brushless DC motors that carry current without the use of brushes. While brushed motors may suffer from complex issues due to their more complex designs, the design of 12V brushless DC motors has eliminated many of these issues. 
The main components of a 12v brushless motor are a permanent magnet outer rotor, three coils or a single-coil, sensor, and drive electronics. Instead of using brushes to transmit current, a 12v brushless motor transmits current through a sensor, which is known as a Hall effect sensor. While a 12v motor can also refer to a type of alternating current (AC) motor, it is very rare compared to the overwhelming popularity of 12v DC motors. Now by having a piece of initial information about voltage, 12 v, and 24 v. It is time to talk about some 12V submersible pumps that are capable of pumping groundwater up to 36.5 m (120 ft) below the surface in shallow water conditions at flow rates up to 13.5 L/min (3.6 US GPM). Continuous flow is very simple to adjust using the unique dial of the 12V pump controller. The sleek, short design of the 12V submersible pump (6" nominal) means it can easily fit into wells that may not be straight without hanging up. There are many reasons for using the 12V submersible pump for groundwater sampling applications. It is very easy to use, and adjustable from high to low flow rates. 
Pump design prevents jamming in non-straight or non-vertical wells. It is mounted in PVC pipe with a nominal 2" Schd OD. 40 or 80. It has convenient LED lights indicating the 12V pump controller and pump status. Having a lightweight, compact and portable system. 12V Pump Controller. The 12V submersible pump is connected to the 12V pump controller and then clamped to the 12V power supply. Push the sampling hose onto the barbed fitting of the 12V pump. Turn the 12V pump controller dial clockwise. The clock increases the voltage to the controller, causing the pump motor to spin faster and increase Sample/Purge flow. The 12V submersible pump is suitable for high and low-flow groundwater sampling for general chemistry, and a high purge rate when sampling with a three-volume purge protocol. And performing pressure head tests in a high K (hydraulic conductivity) environment. 12 V submersible pumps become common due to their application in different environments. 
Franklin electric submersible motor repair
although Franklin Electric manufactures high-quality submersible pumps, they need to be repaired sometimes. All types of submersible pumps can provide decades of reliable performance if you can properly maintain them and monitor wear. It is possible to use some useful tips to monitor any changes and schedule proper service for your submersible pumps, whether they're for your own property or for an industrial application. It is needed to keep checking regularly. Submersible pumps are often invisible for extended periods of time. However, you can perform some simple maintenance checks to ensure optimum performance and longevity. The first is to monitor the flow of the pump to make sure everything is working properly. On the face of it, be sure to check for leaks, assess the condition of electrical wiring, and make sure to replace valves and seals in a timely manner following the manufacturer's or supplier's instructions. It's a good idea to schedule at least an annual maintenance inspection with your repair team, who will provide you with a record of each service and what was inspected. 
By regularly monitoring for these signs of failure or poor performance, you'll be better able to troubleshoot pump problems before they get out of hand. If the pump is not running at all, check for a tripped circuit breaker. Possible reasons for a drop in production may include low water tables or liquid supplies, sand or gravel blockages, restricted impellers, or general wear. If water is splashed on the surface, you may have a problem with a broken water pipe, or your submersible pump's check valve may be damaged. If you have difficulty identifying the problem, you can call a repairman to assess the problem. If you hear the motor making noise, take it out of service and book pump service as soon as possible. If you hear noise from the pump itself, it could be due to a low fluid level (if the pump is pumping air part of the time), or a stuck or faulty component. Overheating of a submersible pump can sometimes indicate that there is not enough water in the well to keep it cool or that the pump is malfunctioning. If the motor overheats, it is important to have it checked to avoid more expensive repairs or replacements. 
If the fluid you're pumping is unusually clogged or cloudy, there may be a problem with sediment or sludge in your system. Possible solutions might include digging a deeper well for the pump or flushing the pump to clear any blockages. Submersible pumps usually don't work all the time, and if this happens, it could be a sign that your float switch or pump is faulty. Higher power consumption may also indicate insufficient turbine clearance or a clogged system. To repair a Franklin Electric submersible pump, some tools are needed such as a flashlight, tripod, winch, and multimeter. It will be mentioned here step by step but before that remove the pump and associated piping from the well to repair the deep well submersible pump. The pump consists of a motor and an impeller. It may also have a check valve to prevent backflow, and a vent line attached below the pump. Start with a visual inspection, followed by electrical and mechanical testing to identify the specific component that is damaged. 
Once the damage is found, the entire damaged unit may need to be replaced. Or, if the damage is limited to a small part like a gasket or protective cover, that part can be replaced. The first step is to turn off the power and lock out the circuit breaker or disconnect the switch. Remove the cover from the well and shine a flashlight into the well. You will need to disconnect the pitless adapter and reassemble the hose, cable, and pump. Look for a hose, chain, or rope to lower the pump into place. Use it to lift the pump and hose, then slide the pitless adapter out of the bracket. If not, place a chain under the elbow of the pipe leading to the pitless adapter and pull the pipe up. Small wells with pump power less than 1/2 horsepower, pipe diameter less than or equal to 1/2 inch, and length less than 100 feet can be lifted by hand. Larger units are too heavy and require a tripod and winch to transport. The second step is to visually inspect the pump. Check for moisture on the pump and tubing string to make sure the pump is actually submerged. 
Otherwise, you will need to add tubing to position the pump deeper in the well or drill the well itself deeper. Check for obvious damage. Debris in the well can cause mechanical damage. This damage can usually be repaired by replacing the pump cover or housing. One-way valve or vent line may be blocked and can be released. The next step is to check the motor for damage. Expel the engine cover where the cable enters the engine. One of the wires in the cable goes to the start capacitor. Switch the multimeter to resistance testing and connect it to the capacitor. The needle should jump. If not, or if the meter shows zero resistance, the capacitor should be replaced. Check motor resistance. 
An open circuit means a bad connection or a blown winding or connection. Zero resistance means the motor is shorted. In either case, the engine must be supplanted. The last step is to check the impeller for any mechanical problems. Turn the motor with a screwdriver and see if the wheel spins freely. If not, open the impeller housing and clear the obstruction. Check the impeller for cracks and check the seals at both ends for wear or clearance. In the event of mechanical damage, the wheel itself or the entire wheel must be replaced. Reassemble the repaired unit and lower the pump and piping into the well. When the pump is in place, make sure the no-pit adapter snaps into place. Close the manhole cover.

Franklin electric submersible motor specifications
Franklin Electric’s submersible motors has different situations based on the different environments Submersible pumps are very popular for their excellent versatility and reliability, and for good reason. They have gained a good market share in industrial and domestic use. They do not require startup, avoid cavitation problems, and are very effective. With our vast knowledge of submersible pumps, we've provided you with the perfect guide to factors to consider before purchasing a submersible pump. Submersible pumps are designed so that they can be submerged in water and the pump. A submersible pump is a centrifugal pump with an impeller designed to throw water outward. The impeller blades are backward curved types. Several wheels are attached to a shaft driven by an induction motor. Water enters through the eye of the wheel. 
It is then rejected radially due to the centrifugal force involved, and this motion provides kinetic energy and pressure to the water. This water is then transported through a diffuser to subsequent stages of the impeller. The pressure gain of each stage is multiplied as water passes in front of each impeller. The water then goes through a check valve without banging. This solves the high-altitude surge problem known as the water hammer. The working method of the pump makes it very efficient, convenient, and reliable in a variety of applications. The popularity of submersible pumps has increased since the 1960s, and industries are looking for multiple benefits due to their submersible capabilities. Their popularity and ease of use make them an essential part of pumping. All submersible pumps use the same mechanism and working principle. But these pumps are designed differently depending on their use and purpose. Each pump differs in technical details and application. 
They are also available in various models such as:
- Borehole submersible pumps,
- Open well submersible pumps,
- Horizontal open well pumps,
- Vertical multistage pumps,
- Deep well submersible pumps, and many more.
Before purchasing a submersible, you need to compare the make, model, and other relevant factors based on your usage. We have carefully prepared a list of factors to help you choose the right submersible pump. The primary factor is the sort of water. Before buying a submersible pump, the most important thing is to know the type of water you are pumping. The specifications of submersible pumps vary depending on the type and location of the water. The first type is Clear Water Submersible Pumps. Narrow submersible pumps with a maximum particle size of 5mm are ideal if you want to collect clean water such as rainwater and pump it out for storage. 
You also need to check how much dirt is going out with the water. The second sort is the Dirty Water Submersible Pump. If the water you are pumping contains a lot of dirt, you will need an ideal dirty water pump. These pumps must function properly even with mud and dirt particles. These pumps can be used to clean sewers and septic systems. Particle size is one of the most important factors to consider before purchasing a submersible pump for sewage. The desired gain diameter you are looking for is 10-20mm. The third one is Submersible Well Pumps. These pumps are commonly used to pump water from home plumbing systems. Not all pumps are suitable for pumping very deep groundwater, which is why submersible pumps are used to pump water from deep wells. The last type is Garden Pond Submersible Pumps. 
Submersible pumps are required to run fountains or manage flowing streams. The pump can be put directly into the water. There are different types of pumps available for fresh and salt water. The second factor is the Float switch and flow switch. This is another important factor to check before buying a submersible pump is the float switch. This switch is used to control the water pump according to the water level. In many cases, there is no water in the area you are pumping, so this switch is used to stop pumping. Running a submersible pump with water can cause serious damage, and the float switch will automatically shut it off when the water level drops to a lower level. The flow switch is used to determine the amount of water that will pass through the pump at any given time. They come in two types - vertical switches for small submersible pumps, usually with a 10" diameter, and fixed switches for pump start, with a 14" diameter. The third factor is Discharge height. 
Generally, a submersible pump is used to pump water from a low place to a high place. This is the discharge height. It is used to determine if the water will reach a specified height. If you want to pump the water from the rain barrel to another container, your discharge height will be a lot less. However, if you wish to pump water from the ground to a higher location, you will need a higher discharge height. The next factor is the Discharge rate. The discharge rate defines the amount of water that the submersible can pump per hour or minute. Typically this is known as the pump power level. If you wish to pump water out of a bucket, a power level of 250-500 per hour is sufficient for this application. If you want to pump water from your basement, you'll need a submersible with a high power level i.e., discharges 1-2 gallons per hour. The backup system submersible pump is powered by voltage and it is known as the fifth factor. 
Therefore, it is important to obtain a pump with backup power to avoid flooding and harsh cleaning processes that rely heavily on electric pumps. A pump with a battery will provide power and make it last a long time in an emergency. The next factor is the Cooling system. The submersible motor is filled with oil or water. For a water-injected engine, the coolant is water and can be refilled repeatedly. But with the engine full of oil, there is no coolant, which increases the risk of engine wear and damage. That's why you'll find priming pumps more expensive than oil priming pumps, but choose wisely. Suction depth is the next factor. When pumping water, the water level drops. Sometimes the suction assembly is not even fully covered with water, which can allow air to get in and prevent the pump from doing its job. This is called the suction depth. 
This is the water level at which the pump is operating. Also, the Outlet size is another factor. The submersible pump must be connected to the outlet pipe through which the water passes. They are available in a variety of sizes for different applications. The size of the outlet should match the size of the piping connecting the tank. Outlet Size Diameter is usually in inches and millimeters. The last factor is Drill size this is the size of the hole where the submersible is placed, commonly referred to as the borewell. You can check the diameter of the pump and dig the borewell. The bigger the pump, the bigger the borewell. You can also fit small subs in larger borewells, but not the other way around.
