Centrifugal pumps are widely used in various industries for transferring liquids. These pumps consist of several key rotating parts that play a crucial role in the pump's operation and efficiency. Understanding the different rotating parts of a centrifugal pump is essential for proper maintenance and troubleshooting. In this article, we will explore the main rotating parts of a centrifugal pump and their functions.
The Centrifugal pumpis working based on the centrifugal force and the name follows the same. Fluid enters into the pumps, gets the energy from the centrifugal force of the impeller, and raised its velocity and pressure. Due to this pressure, the liquid is transferred from one place to another. See more
Impeller
The impeller is a critical rotating component of a centrifugal pump. It is responsible for imparting kinetic energy to the liquid being pumped. The impeller typically consists of curved vanes or blades that rotate rapidly when the pump is in operation. As the impeller rotates, it creates a centrifugal force that pushes the liquid towards the outer edges of the impeller. This action increases the liquid's velocity and pressure, allowing it to be discharged through the pump's outlet.
Casing
The casing is the outer shell of the centrifugal pump that encloses the impeller and other internal components. It serves to contain the liquid being pumped and direct it towards the discharge nozzle. The casing is designed to withstand the pressure generated by the impeller and maintain the pump's efficiency. It also helps to guide the flow of liquid through the pump and prevent leakage.
Backplate
The backplate is a stationary component located behind the impeller in a centrifugal pump. It provides support to the impeller and helps maintain the pump's efficiency by reducing internal recirculation. The backplate also serves as a mounting point for the pump's shaft and bearings, ensuring proper alignment and smooth operation.
Suction & Discharge Nozzles
The suction and discharge nozzles are openings in the pump casing that allow the entry and exit of the liquid being pumped. The suction nozzle is located at the inlet of the pump, where the liquid is drawn in by the impeller. The discharge nozzle is situated at the outlet of the pump, where the pressurized liquid is expelled. Proper sizing and positioning of these nozzles are essential for efficient pump performance.
Suction Pipe
The suction pipe is a conduit that connects the pump's suction nozzle to the liquid source. It serves to transport the liquid from the source to the pump inlet, ensuring a continuous flow. The suction pipe must be properly sized and installed to prevent cavitation and maintain optimal pump performance.
Foot Valve
A foot valve is a type of check valve installed at the end of the suction pipe to prevent backflow of the liquid. It ensures that the pump remains primed and ready for operation by maintaining a consistent flow of liquid. The foot valve opens when the pump is in operation, allowing the liquid to enter the pump, and closes when the pump is turned off to prevent reverse flow.
Strainer
A strainer is a filter device installed in the suction pipe to remove any solid particles or debris from the liquid before it enters the pump. The strainer helps protect the impeller and other internal components from damage caused by foreign objects. Regular cleaning and maintenance of the strainer are essential to prevent clogging and ensure uninterrupted pump operation.

Introduction of Screw Pump - Free download as Word Doc (.doc), PDF File (.pdf), Text File (.txt) or read online for free. Screw pumps operate by using one driver screw and two driven screws that rotate to move fluid axially from the pump's inlet to its outlet. As the screws rotate with a small clearance between them, pockets form in the screw threads that act like pistons to displace .
