CARRIER ASSEMBLY FOR A PUMP
First Claim
1. A pump assembly comprising:
- 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;
a cartridge having a pump stack including a plurality of pumping stages, each pumping stage including an impeller, the cartridge extending between a first end and a second end, the first end being removably coupled to the manifold; and
a carrier assembly supporting the cartridge, the carrier assembly moving the cartridge between an advanced position and a retracted position, the cartridge engaging the manifold in the advanced position, the cartridge disengaging from the manifold in the retracted position.

Abstract
A 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 pump assembly also includes a cartridge having a pump stack including a plurality of pumping stages. Each pumping stage includes an impeller. The cartridge extends between a first end and a second end. The first end is removably coupled to the manifold. A carrier assembly supports the cartridge. The carrier assembly moves the cartridge between an advanced position and a retracted position. The cartridge engages the manifold in the advanced position and the cartridge is disengaged from the manifold in the retracted position. Optionally, the carrier assembly may include a support frame and at least one rail. The support frame is slidable along the rail and the cartridge is supported by the support frame.

18. A pump family of multistage pump assemblies comprising:
-
a manifold having an inlet port configured to be coupled to a supply pipe and a outlet port configured to be coupled to a discharge pipe, the manifold having a mating interface; a pump motor; a carrier assembly supporting the pump motor, the carrier assembly moving the pump motor relative to the manifold; a first pump unit including a cartridge having an end plate, a pump head opposite the end plate and a pump stack extending between the end plate and the pump head, the pump stack of the first pump unit having M number of pumping stages, and a second pump unit including a cartridge having an end plate, a pump head opposite the end plate and a pump stack extending between the end plate and the pump head, the pump stack of the second pump unit having N number of pumping stages different than the M number of pumping stages of the first pump unit; wherein the first and second pump units are configured to be separately coupled to the manifold and the pump motor, the end plates being configured to be coupled to the manifold at a separable manifold interface, the pump heads being configured to be coupled to the pump motor at a separable motor interface. - View Dependent Claims (19, 20, 21, 22)
