Centrifugal Pumps

A centrifugal pump is a pump in which a rotating blade row called an impeller is used to increase the pressure of the fluid through the pump. The flow enters axially, aligned with the shaft of rotation. The fluid is then turned by the impeller blades until it is flowing radially away from the axis of rotation. The flow exits the impeller into a diffuser or casing prior to exiting into the piping system. The performance of the pump will be dictated by the rotational speed of the pump, the frictional losses through the impeller, and the pressure rise achieved.
