Deflecting vanes (26, 28, 30), confronting the blades of the impeller-inducer (14a), and fixed in the housing, inhibit the formation of a vortex upstream of the impeller-inducer (14a). 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. |
