On the other hand, a centrifugal pump is unable to create a pressure differential by priming without liquid already in the unit. Some PD pumps (rotary lobe) can be used in applications where you need to be able to control the flow rate. These pumps can be adjusted as needed to match other parts of your process or for rough metering of fluids.

The pump’s impeller rotates within the housing and reduces pressure at the inlet. This motion then drives fluid to the outside of the pump’s housing, which increases the pressure enough to send it out the discharge. There is also the axial flow centrifugal pump which uses a curved propeller-shaped impeller, whereas the impeller on a radial flow centrifugal pump looks more like a fan.

Centrifugal Pump, It consists of an impeller, which rotates and creates a ,centrifugal, force that imparts Kinetic energy to the fluid, inducing a flow from a low level to a high level. These pumps are widely used within mining, manufacturing, and agricultural industries due to their large volume handling capacity, small size, user-friendliness, and easy maintenance features.

The pump does not rely on raising the velocity of the fluid as the centrifugal pump does by moving the liquid through the impeller. Consequently, the fluid velocity inside a positive displacement pump is much lower than that of a centrifugal pump.

There the fluid exits the ,pump, at a higher velocity. You can classify ,centrifugal, pumps by the type of impeller they use. Radial flow ,centrifugal, pumps are the most common type. They use a rotating impeller that creates a vacuum to move fluid. This fan-like impeller rotates within the ,pump, housing to reduce pressure at the inlet.
