A type of hydraulic pump that uses the centrifugal principle to move fluids. Fluid enters the pump through the center of the impeller which rotates rapidly. Due to the centrifugal effect, the liquid is pushed out of the impeller towards the outer edge, then into the pump casing and finally out through the outlet channel. Centrifugal pumps are widely used because of their simple design, ability to convey large volumes of liquid, and ease of maintenance.

Types of Centrifugal Pumps

Centrifugal Pumps Based on Number of Impellers:
Single-Stage Pump: Has one impeller, generally used for applications with low to medium pressure requirements.
Multi-Stage Pump: Has more than one impeller arranged in series, used for applications that require high pressure.

Centrifugal Pump Based on Shaft Orientation:
Horizontal Pump: The impeller shaft is installed horizontally, easy to maintain and access.
Vertical Pump: The impeller shaft is installed vertically, saving floor space and is often used in wells or applications with limited space.

Centrifugal Pumps Based on Impeller Type:
Closed Impeller: High efficiency, suitable for clean or slightly dirty fluids.
Open Impeller: Easier to clean and suitable for liquids containing solid particles.
Semi-Closed Impeller: A combination of closed and open impellers, used for fluids with high viscosity or few solid particles.

Centrifugal Pump Based on Casing Configuration:
bVolute Pump: Has a volute-shaped casing to convert fluid velocity energy into pressure energy.
Diffuser Pump: Has a diffuser at an angle that helps increase efficiency by reducing the velocity of the fluid before it exits the pump.
