Centrifugal Pump

Working Principle
A centrifugal pump is mainly composed of impeller and volute casing or impeller and guide vane. During working, the impeller rotates at a high speed and creates a vacuum at the impeller eye as a result of the centrifugal force, and this vacuum continuously draws more fluid into the impeller. From pump inlet to pump outlet, the impeller transfers rotational kinetic energy to the liquid flow, and the liquid, with high velocity, moves from the impeller into the volute casing or guide vane, in which its velocity energy is converted into potential energy which is represented by fluid pressure, and then the pumped liquid is discharged.

The abovementioned process cycles again and again, thereby realizing liquid transportation and pressure boosting.
