Each centrifugal water pump is made up of dozens upon dozens of individual components. There are several parts where are located across the majority of different types of centrifugal pumps. These pieces can be classified and placed as either moist or mechanical depending on their function. The portion of the pump known as the wet end houses the components that are responsible for determining the pump's overall hydraulic performance. The impeller and the housing are the two major components that come into contact with liquid. It is possible to use water as the lubricant for the first radial bearing in certain circumstances. In this particular instance, the bearing might also be considered part of the wet end. The mechanical end is where all of the components that hold the impeller in place within the housing are located. The pump shaft, seals, bearings, and shaft housing are all components that make up the mechanical end of a pump.
- Crankcase or main body
The body of the pump is sometimes referred to as the casing. This makes up the majority of the pump's overall size. Have the ability to be made or manufactured specifically for casting. 
The majority of pumps that are seen in processing facilities have bodies that are cast. For particular purpose pumps that are either difficult to cast or expensive to do so, made or manufactured housings are utilized. The body of the pump is where all of the other components are housed. It also offers passage for liquids. Because it redirects energy, the spiral body design contributes to an increase in head pressure. Depending on the pressure and fluid qualities, it can be constructed out of a number of further fabrics, including carbon steel, stainless steel, and alloy steel, amongst others. There is a wide variety of casing design options available to meet the many sorts of pump designs.
- Both a single and a double spiral make up the body
Both the single case and the double case styles are displayed here for your viewing pleasure. Jacketed casings are used in large radial force pumps to limit the amount of casing forces.
- Bodies with single as well as double suction
Both a single and a double suction case design are depicted in the images that are presented here. A design that features double suction enables liquid to enter the impeller from both of its sides. Suctioning is a more involved process than simple vacuuming. 
- Bodywork with a single or more stages
Single-stage pumps are often smaller and less expensive than their multi-stage counterparts; but multi-stage pumps come in very larger sizes.
- Body that is split radially and axially
The body of the pump can be constructed in a manner that is appropriate for either the radial or the axial orientation of the pump. These gentlemen are visible in the picture over here. Impeller When it comes to pump operation, the impeller is the single most critical component. The efficiency of a pump is determined by the design and selection of the impeller. Energy is transferred from a conducting medium to a fluid in this process. Performs the process of transforming kinetic energy into pump pressure. Curved blades, which are also known as vanes, are attached to the pump shaft and make up the impeller. There are three fundamental types of turbines that can be constructed. The identical scene may be seen in this photograph. 
- The open wheel configuration is the most basic one. This particular kind of turbine has blades that are perforated on the sides. Because of the way it is constructed, it has a lower overall strength compared to the other two varieties. Services that make use of particles typically make use of open impellers. This particular type of impeller may also be found in pumps that are lower in cost but have a poorer durability.
- In a semi-closed turbine, one side of the turbine blade is joined to a circular disc. This design allows for more efficient use of the available space. These wheels are superior to open wheels in terms of both strength and performance. This impeller is able to process liquids that include particular particles without becoming clogged.
- Pumps that are utilized in treatment plants will have closed impellers installed in them. In this particular species, both sides of the wing are folded inward. This gentleman is captured in the accompanying photo. The production of a closed impeller is both time-consuming and resource-intensive. It provides the highest possible performance and is very efficient. It can only be utilized in liquids that are transparent and cannot be utilized in liquids that include suspended particles.
Wear Ring You can see the cutting ring that is used to protect the pump body and the impeller from getting damaged here. When the impeller and casing are operating at high speeds, the cutting ring's job is to prevent damage to these expensive components by acting as a barrier. During preventative maintenance, these rings can be switched out for new ones. 
Shaft The pump shaft's job is to transfer the driving force to the impeller, which is the rotating part of the pump. Forged steel having a surface that has been machined. There are cantilever types, such as single-ended suction pumps, and two-ended types, such as inter-bearing pumps, depending on the design of the pump. Cantilever types include inter-bearing pumps. Coupling Pumps and motors are coupled to one another through the use of couplings (engines, motors, turbines). There are two different kinds of pump connections that can be found in treatment plant pumps.
- Fixed or rigid coupling: This type of coupling is utilized in situations in which the motor and the pump are perfectly parallel to one another. Incompatible with the vast majority of pumps utilized in processing plants. Incorrect alignment places a significant amount of strain on the shaft.
- Flexible coupling: The flexible coupling is a form of coupling that is frequently employed in pumps because of its ability to compensate, at least partially, for radial and axial misalignment.
Roller bearings are the most common type used in centrifugal pumps. The bearing's job is to keep the shaft in its proper position and to make it possible for the shaft to move without causing any friction. 
Because the bearings are one of the most critical parts of the pump, a poor choice of bearings might result in the malfunction of the pump. The bearing is inserted into the housing for the bearing in this step. This hose is lubricated to prevent the bearings from overheating and to ensure that they remain sufficiently oiled for optimal operation. The sealing system's job is to make sure that the pump doesn't let any liquid escape while it's running. The complexity is directly proportional to the characteristics of the fluid that is being handled. The pump seal system is both straightforward and intricate. The packaging for the water pump only has to be a simple filling box. When dealing with flammable or poisonous liquids, a specialized sealing system is essential. There is a wide selection of mechanical seals available to choose from in order to fulfill these requirements.
