End Suction Centrifugal Pump Introduction:
End suction centrifugal pumps get their name from the pathway the water takes to enter the pump. Typically the water enters one side of the impeller, and on horizontal end suction pumps, this appears to enter “the end” of the pump. Unlike the HSC the suction pipe and motor or engine are all parallel, eliminating the concern about pump rotation or orientation in the mechanical room. Since water is entering one side of the impeller, you lose the ability to have bearings on both sides of the impeller. Bearing support will be either from the motor itself, or from the pump power frame. This prevents the use of this type of pump on large water flow applications.
The appeal of an end suction pump is usually its lower initial cost. If the pump can perform at a given rating and pressure, then this type of pump is adequate. If diesel-engine driven, another advantage is the ability to have an engine parallel and close to a wall (assuming proper air venting is considered). This can save space in a mechanical room piping layout.
The removal of the impeller requires pulling the impeller back out of the casing, which requires removal of the motor to provide space for this to happen. Often this is a more difficult procedure for those maintaining the pump.

How it Works:
The end suction centrifugal pump normally contains a single impeller and a spiral like casing. The fluid that is being pumped moves along the impeller’s vanes, which increases the fluid’s velocity. From there the fluid is moved into the spiral like casing, where the high velocity is transformed into high pressure by a diffusion process.
These types of pumps are usually powered by an A.C. electric motor, although some are D.C. motor driven, as well as air driven motors, hydraulic motors, gasoline and diesel engine driven and steam turbine driven. These pumps may be close-coupled, with the impeller directly attached to the driver shaft without a separate coupling between them. Alternatively, they may be mounted on a frame, where the pump has its own bearings and a coupling that separates the motor and the pump.
The end suction centrifugal pump is useful in various residential, industrial and commercial applications. Due to the fact that the pumps are highly common and readily available from many suppliers, their prices are usually very attractive.
Standard end suction centrifugal water pumps are normally close coupled and manufactured from standard iron or a variety of plastics. Pumps that are meant for more heavy duty commercial and industrial applications are often mounted on a bedplate with a coupling that separates the motor and the pump. These are usually available in stainless steel and more exotic alloys or plastics for corrosion resistance, while others are manufactured from hardened iron for mining, slurry and dredging applications.
