Centrifugal pumps work on the principle of converting rotational kinetic energy into hydrodynamic energy to move fluid through the pump.

• Centrifugal force is generated by the rotation of the impeller within the pump casing

• Fluid enters the pump through the center of the impeller and is flung outwards by centrifugal force

• The fluid is then directed towards the pump outlet by the pump casing

• The kinetic energy of the fluid is converted into pressure energy as it moves through the p...read more
