A pump for pumping a liquid containing solids comprises a housing having a first end and second end and an interior pump chamber. An inlet pipe leads to the pump chamber through the first end, and an outlet pipe leads from the pump chamber at the second end. A core having a vane extending therefrom rotates within the chamber. The core has hollow portions permitting material to move from the inlet pipe to the pump chamber and from the pump chamber to the outlet pipe. The vane extends from the core outwardly, seals against the housing, and works in cooperation with a pair of moving blades to draw material from the inlet pipe and expel the material through the outlet pipe. The blades, which are arcuate in shape and have curved ends, are operated by pneumatic cylinders and move from a retracted position in which they are positioned out of the pump chamber to a deployed position in which the curved end sealably engages the core.
