A centrifugal pump is a rotodynamic pump that uses a rotating impeller to increase the pressure of a fluid and are commonly used to move liquids through a piping system. When 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 where it exits into the downstream piping system. Centrifugal pumps are used for large discharge through smaller heads.
Types of Centrifugal Pumps
Centrifugal pumps have many variations, for instance you can get an end suction centrifugal pump which offers discharge on the top of the pump, with many types of variations, centrifugal pumps are a very versatile type of pump.
