Abstract: Single suction centrifugal pumps, pump casings, pump systems and vehicles for using pumps which include a single piece casing having a first cut-water wall and a second cut-water wall, corresponding joint-water paths communicating with respective discharge nozzles, the second cut-water wall spanning less than 180 degrees from a leading edge of the second cut-water wall to a trailing edge of the second cute-water wall, and in aspects, the discharge nozzles are offset from a horizontal centerline of a center opening of the casing, the cut-water walls define a diameter which is greater than 1.07 times the impeller diameter, and the diameter is constant for a portion of the walls and transitions to a varying diameter at trailing ends of the walls.

Abstract: Single suction centrifugal pumps, pump casings, pump systems and vehicles for using pumps which include a single piece casing having a first cut-water fluid flow path, a first discharge nozzle, and a second discharge nozzle, the first cut-water fluid flow path communicating with the first discharge nozzle and the second discharge nozzle and the nozzles being situated at opposing ends of the pump such that center outputs of the nozzles are offset from a horizontal centerline of the casing and the first nozzle is positioned a greater distance from a lower casing wall of the pump as compared to the second nozzle so that the casing may be connected to output piping for both sides of the vehicle and at a low profile within the vehicle.

Abstract: A pump having two impellers driven by a common drive shaft where the impellers have suction inlets facing each other and are configured to axially receive fluid from a common chamber. A direct line path exists between suction inlets of the respective impellers. A mechanical seal having a two-piece housing is positioned with a first cup component of the housing fastened at an inboard side of an outboard head of the pump.
