ABSTRACT:
A centrifugal pump has a bladed impeller rotating in the bowl of the pump casing. The inlet side of the pump bowl is closed by an intake plate. A hub rotated with the impeller extends through the intake plate, generally axially outward from the impeller blades. The hub has an abrupt projection in close cutting relationship with at least a portion of the intake plate as the impeller is rotated.
