ABSTRACT:
A pump for grinding materials contained in a liquid includes a comminutor located at the pump inlet to grind the material as it passes therethrough and into a pumping chamber. The pumping action is created by an impeller which communicates with the pumping chamber but which is located outside thereof to draw the material through the comminutor and into the chamber for radial discharge therefrom. The comminutor includes a stationary annular ring in the inlet having a plurality of grinding teeth which form the internal diameter of the ring. A cutting impeller is rotatable within the ring and has at least one blade which extends from one side of the impeller body axially outwardly beyond the ring to force the material between the teeth of the ring. The other side of the impeller body is provided with means to provide additional shearing of the material and prevent clogging of the material between the teeth of the ring.
