Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an engine or electric motor. The working principle of centrifugal pumps involves imparting energy to the liquid by means of a centrifugal force developed by the rotation of an impeller that has several blades or vanes.

Centrifugal Pumps – In this video we learn the basics of how centrifugal pumps work, the main parts of centrifugal pumps, how the electrical motor powers the pump impeller and how the impeller moves water in the HVAC system.
Centrifugal Pumps are a sub-class of dynamic axisymmetric work-absorbing turbomachinery.The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller, flowing radially outward into a diffuser or volute chamber (casing), from which it exits.
Common uses include water, sewage, agriculture, petroleum and petrochemical pumping. Centrifugal pumps are often chosen for their high flow rate capabilities, abrasive solution compatibility, mixing potential, as well as their relatively simple engineering./wikipedia
