Centrifugal Pumps

“Centrifugal pumps rely on kinetic energy rather than mechanical means to move liquid. Liquid enters the pump at the centre of a rotating impeller and gains energy as it moves to the outer diameter of the impeller. Liquid is forced out of the pump by the energy it obtains from the rotating impeller.

Centrifugal pumps can transfer large volumes of liquid but efficiency and flow decreases rapidly as pressure and/or viscosity increases.”
