    Abstract: A pump is provided including a cutter plate disposed at a pump inlet including a plurality of holes. Multiple embodiments provide that the pump includes a rotatable cutter blade disposed substantially adjacent to the cutter plate. Embodiments include those wherein the plurality of holes are angled in a direction of rotation of the cutter blade. In some embodiments, the cutter blade has at least one relief hole and at least one cutting edge. Additional embodiments include those wherein a ring extends outward from the pump inlet for channeling material toward the pump inlet in a substantially perpendicular approach with respect to the cutter plate.

    Abstract: A reinforced resilient wiper element, for use in connection with internal pipe wipers, having peripheral wiping edges, a central bore and a rigid area surrounding such central bore. The rigid area surrounding the central bore prevents compression of the resilient wiper element in the vicinity of the central bore, thereby reducing or eliminating structural failure of the wiper element.
