This type of electric agricultural pump is a type of centrifugal pump called submersible, used for irrigation and is composed of two parts: electric motors and pumps that are placed in the water as floating or submerged and their task is to discharge water from the well for drinking, agricultural and industrial uses. Water scarcity is a common problem in most parts of the world, and on the other hand, scattered rainfall and uneven presence of water resources such as rivers, springs, and it creates the need to extract groundwater. The solution is to extract groundwater for agricultural, industrial, domestic, and… use of water pumps. A submersible pump consists of two separate parts, a pump and an electric motor (floating alternator), which are completely sealed and are usually coupled together by flanges and screws. 
These pumps are produced in two types single-phase and three-phase. This product is immersed in water and inside the electric motor, which acts as a lubricant for the bearings and cools the coil in the electric motor. Usually, the main body of this pump is made of steel or cast iron and its impeller is made of steel. Usually, the type of body and bronze impeller of this water pump are used to extract saltwater. The single-phase type is used in shallow wells and high-depth wells, and the three-phase type is used. These types of pumps are designed for submersible wells and the electromotor of the floats is cooled by the cooling fluid and water flow on the electromotor shell.
Submersible Agricultural Irrigation Pump
In the agricultural industry, for artificial irrigation of agricultural lands, submersible agricultural pumps are usually used, which have been widely welcomed due to their advantages over other types of pumps. The water pump is a versatile device. This product is very suitable for agriculture areas with low water pressure. For daily consumption, this device can be used to increase water pressure. Farmers and gardeners must use an efficient irrigation system to maintain their crops and green space to see their crops grow properly. For proper irrigation of lands, the use of pumps is essential. 
A submersible pump is a type of pump that transmits water from wells and pools are used for agricultural and industrial purposes it should be said that the irrigation capacity of the submersible pump is from 5 to 650 cubic meters per hour and the maximum height is 300 meters. Body material in most floating models is cast iron, Agricultural water pumps are made of very durable alloys, which makes the pump highly resistant to environmental factors. Most of the alloys used in the construction of the body and motor of these pumps are stainless (because the pumps are more with b They must be made of stainless alloys). And of course, it must be said that submersible pumps have their characteristics which are; Energy-saving, low maintenance costs, and high strength as well as there are other benefits to Submersible pumps.
Water Pumps Used in Agriculture
The water pump is a versatile device. This product is very suitable for agriculture areas with low water pressure. For daily consumption, this device can be used to increase water pressure. Farmers and gardeners must use an efficient irrigation system to maintain their crops and green space to see their crops grow properly. For proper irrigation of lands, the use of pumps is essential. Submersible pumps are divided according to the number of floors, the amount of discharge, and the height that can be pumped. 
The submersible pump is installed vertically, but in some cases, due to the number of floors and the size of the motor, it can be installed horizontally. Steel float is more useful due to its high strength. Floating water pumps are used in firefighting, water purification and removal of clean water from deep and semi-deep wells, emergency water supply, residential and industrial water supply systems such as mines, drip pressure irrigation, and sprinkler irrigation systems. The benefits of submersible pumps are as follows; Priming: Submersible pumps do not need to be primed, they are priming because they work below the surface of the pumped fluid. 
Cavitation: Submersible pumps are not prone to cavitation due to complete water immersion, this can cause problems with centrifugal pumps and other types of positive displacement pumps. Efficiency: When a submersible pump is submerged, there is a positive fluid pressure at the pump inlet, which can increase efficiency due to the less energy required to move the fluid in the fluid path of the pump. Noise (sound): These pumps are very quiet due to water immersion.
Farm Irrigation Systems
If we want to classify farm irrigation systems in general, we must say that irrigation systems are divided into two categories (surface irrigation and pressure irrigation). Since the heart of most irrigation systems is the pump, choosing the right type of pump for the irrigation system is very important and should be as efficient as possible. The choice of irrigation pump is based on the type of pump and also on the relationship between pump efficiency and total dynamic head (TDH) with a specific flow rate. When choosing a suitable agricultural irrigation pump, consider the operating conditions of the pump, including: Type of water source The amount of pumping flow required (determined by the required irrigation system) General suction head (raising from the water level to the consumption pump) Overall dynamic head (total pressure supplied by the pump) Surface water or well water determines the source of water for you and its availability is determined by local geology and hydrological conditions. The type of irrigation system, the distance from the water source, and the size of the piping system determine the overall flow rate and dynamic head. The application of the pump in today's irrigation systems must be considered a unique design as well as considering the ground conditions and the desired activity. 
Modern irrigation methods used today include a complex system of sustainable energy consumption, water use, different market conditions, use of knowledge, and experience to ensure the best design to create a suitable irrigation program. Irrigation begins from water sources, including groundwater or surface water, and canals and ponds. After reaching the water source, we reach the stage of purification (if necessary) or adding fertilizers, toxins, and chemicals, Finally, after completing all these steps, it is transferred to the product using various techniques such as slag, drip, micro or spray irrigation.
