摘要： The disclosed solid waste pump is a chopper pump, and preferably a chopper pump having a small rated motor and a semi-open impeller design. Particularly, a chopper pump having an impeller, at least one pump-out vane, an end plate, and a back plate including at least one cutting rib is disclosed. The impeller includes a back shroud and cutting vanes sharpened on a first edge extending opposite the back shroud and fixed on a first surface of the back shroud. The at least one pump-out vane is preferably fixed to a second surface of the back shroud opposite the first surface, while the end plate includes a surface adjacent to and facing the first edge of the cutting vanes and at least one internal cutting rib fixed to the end plate surface for shearing operation in combination with the sharpened edge of the cutting vanes of the impeller. Finally, the back plate has a surface adjacent to and facing the at least one pump-out vane and at least one cutting rib attached to the back plate surface for shearing operation in combination with the at least one pump-out vane.

摘要： A cutting assembly for positioning at the intake end of a centrifugal pump used for pumping liquids and slurries containing solid matter, including various types of refuse, and for chopping the solid matter which may thereafter be processed for disposal is disclosed. The cutting assembly includes an intake end plate having a body defining the opening to allow the passage of material, such as waste water and the like, therethrough. The intake end plate attaches at the intake end of the chopper pump. The assembly also includes at least one, and preferably a plurality of cutter bars projecting from the body of the intake end plate into the opening, and a nut positioned at the intake end and attached to the chopper pump within the opening of the intake end plate. Preferably, the nut comprises at least one raised cutting projection having a cutting edge formed at a junction between a first surface and an adjacent second surface, the cutting edge of the raised cutting projection providing aggressive cutting action in coordination with the cutter bars.
