Abstract:
1. A centrifugal impeller/propeller pump system for pumping liquids with suspended solids, the system comprising: a housing comprising a front side having an inlet, an opposite rear side having a rear outlet, and a periphery having a peripheral outlet and defining a chamber therein in fluid communication with the inlet, the rear outlet and the peripheral outlet, the inlet and the rear outlet being oppositely disposed relative to each other along the same axis defined between the opposite front and rear sides; a rotatable assembly being at least partially positioned within the chamber and comprising: an actuator operatively communicating with the rotatabale assembly for imparting a rotational movement thereto, wherein the rotational movement of the rotatable assembly provides for drawing liquid in proximity thereto into the chamber through the inlet, for mixing the suspended solids in the liquid within the chamber and for expelling the liquid in the chamber via the rear outlet and the peripheral outlet, the liquid being drawn into the inlet and expelled through the rear outlet directly into the ambient environment along the same axis defined between the opposite front and rear sides.
