Centrifugal pump works on reverse of the principle of working of radial inward flow reaction turbine. The pressure at the periphery will be high due to centrifugal force on water. The centrifugal force is subjected on water due to forced vortex motion. Water enters in axial direction and leaves in radial direction (Figure 9.16). The pressure is proportional to square of radius as rise in pressure head.

Due to high pressure head at periphery, water can be lifted to higher level.
