A grinder pump which includes a housing; a shaft disposed within the housing having an axis; apparatus for mounting the shaft within the housing for rotational movement thereof; a moveable cutter carried on the shaft, apparatus for coupling the moveable cutter to the shaft to cause rotation of the moveable cutter upon rotation o f the shaft. A stationary cutter is carried by the housing and the moveable cutter cooperates with the stationary cutter to perform cutting along respective surfaces of the moveable cut- ter and the stationary cutter. The respective surfaces of the stationary and moveable cutters are substantially within a plane that is substantially perpendicular to the axis; and apparatus resiliently biases the moveable cutter against the stationary cutter.
