ABSTRACT:
Deflecting vanes, confronting the blades of the impeller-inducer, and fixed in the housing, inhibit the formation of a vortex upstream of the impeller-inducer. Too, the vanes direct the recirculation flow back into the central zone of the pump. The impeller-inducer is force-fed by its own recirculation.
