How a Centrifugal Pump Works
Fluid Enters
Liquid enters the pump eye (centre of impeller) along the shaft axis at low pressure from the suction pipe.
Impeller Accelerates
The rotating impeller vanes impart kinetic energy to the fluid, flinging it outward by centrifugal force at high velocity.
Volute Converts
The expanding volute casing slows the fluid, converting velocity head (kinetic energy) into pressure head.
