Abstract: A multistage pump assembly includes a manifold having an inlet port configured to be coupled to a supply pipe and an outlet port configured to be coupled to a discharge pipe. The inlet and outlet ports define an end suction, radial outlet port configuration. The pump assembly also includes a cartridge having a sleeve and plurality of pumping stages that define a pump stack received within the sleeve. An outer chamber is defined between the pump stack and the sleeve. Each of the pumping stages includes an impeller mounted along a pump shaft that rotates about a rotation axis. The cartridge is aligned horizontally such that the rotation axis is substantially horizontal. An end plate is positioned between the manifold and the cartridge and includes at least one cartridge engagement surface supporting the cartridge. The end plate is removably coupled to the manifold.

Abstract: A modular multistage pump assembly includes a volute having a suction side and a pressure side, a pump stack having at least one stage, and a modular flange coupled to each of the volute and the pump stack.

Abstract: A pump assembly is configured to fit to a predefined pipe layout defined by supply and discharge interfaces that are positioned in a predefined relation to supply and discharged centerlines, respectively. The pump assembly includes a multistage pump having a plurality of pumping stages mounted along a pump shaft rotating along a rotation axis. The multistage pump has an inlet port and a discharge port, and the multistage pump is aligned horizontally such that the rotation axis is oriented parallel to the supply centerline. The pump assembly also includes an adaptor having a pump interface and a pipe interface, wherein the adaptor has an internal fluid channel extending along a non-linear passageway between the pump and pipe interfaces. The pump interface is coupled to one of the inlet and discharge ports of the multistage pump, and the pipe interface is located proximate one of the supply and discharge interfaces.

Abstract: A modular pump assembly has a volute (16), having a suction chamber (120) and a pressure chamber (122), and a pump stack (14) having at least one stage (86), wherein a modular flange (44) is arranged between the volute (16) and the pump stack (14) and is removably coupled to both the pump stack (14) and the volute (16).
