Abstract
Notches in the impeller cooperate with balancing holes therein, and a liquid-receiving slot, to direct liquid across the leading edges of impeller vanes to flush away any accreted substances therefrom. In addition, a large diameter deflector coupled to the hub of the impeller also cooperates with the notches to deflect the flushing liquid in the direction of the main liquid flow through the impeller.
