ABSTRACT:
The centrifugal pump comprises a unique combination of a centrifugal impeller, inducer and jet pump having the capability of handling incoming fluids with a minimum V/L ratio of 1.0. The motive flow for the jet nozzle is provided by high pressure fluid discharge from the centrifugal impeller, and the high velocity jet is used both to create the suction and entrainment of the fluid coming from the suction inlet and to break up the large incoming vapor bubbles.
