摘要： A pump for chopping solid material in a liquid stream having a volute housing, a rotating cutter with at least one blade parallel to a rotational axis of the rotating cutter, an impeller arranged at an outer circumference of the rotating cutter, and a stationary cutter having at least one blade parallel to the rotational axis of the rotating cutter. The stationary cutter is concentric with the rotating cutter, and the stationary cutter, the rotating cutter and the impeller are all at least partially housed within the volute housing. Typically, the rotating cutter has a different number of blades than the stationary cutter. Optionally, the pump, further comprises an inspection cover that is removably attached to the pump, and has an opening large enough to remove the stationary cutter and the rotating cutter from the volute housing.

摘要： A pump assembly that includes a pump housing defining an inlet for receiving fluid to be pumped and an outlet for discharging fluid. A rotatable impeller operatively coupled to a drive motor includes a plurality of vane structures integrally formed with a shroud. Each vane structure includes a curved, axial vane segment extending axially from the shroud. A compound, multi-step auxiliary vane extends transversely from each axial vane segment. The auxiliary vane or wing includes at least first and second sections, with the second section overlying the first section in a staggered configuration such that the trailing edges of the first and second sections are spaced apart to form a step. The second auxiliary vane section includes an axial surface that also forms a working vane surface for the auxiliary vane.

摘要： In one aspect, there is provided a wear plate for use in combination with a centrifugal pump and impeller. The wear plate has a wear surface defined by a substantially flat surface, a truncated conic section, and/or a curvilinear solid of revolution formed by revolving an area bounded by a curve around a center axis of the wear plate, wherein a notch or recess is provided. The notch or recess extends in a first direction perpendicular to a predetermined direction of rotation of an impeller and a second direction crossing against a direction of rotation of the impeller.

摘要： A release valve (20) for a self-priming pump includes a housing, a valve member (68), an exhaust outlet (104), a guide stem (78), a spring (88), and a bellows (90). The valve is positioned in a valve opening (54) in the housing and is movable between an open and a closed position. The open position permits the travel of air and fluid through the opening. The closed position closes the valve opening. The valve plug is positioned in the valve opening responsive to pressure in the flow passageway of the housing. The guide stem is coupled to the valve plug and the spring is coupled to the guide stem. The bellows surrounds the spring.

摘要： A release valve for a self-priming pump includes a housing, a valve member, an exhaust outlet, a guide stem, a spring, and a bellows. The valve is positioned in a valve 5 opening in the housing and is movable between an open and a closed position. The open position permits the travel of air and fluid through the opening. The closed position closes the valve opening. The valve plug is positioned in the valve opening responsive to pressure in the flow passageway of the housing. The guide stem is coupled to the valve plug and the spring is coupled to the guide stem. The bellows surrounds the spring. c 92 c 90 -i -- 110 Fig. 6
