Benefits of technology

[0005]A need remains for pump assemblies that can accommodate different pipe layouts. A need remains for pump assemblies that can be manufactured at a reduced cost. A need remains for pump assemblies that can reduce inventory.

Problems solved by technology

A problem often encountered is that end-users typically mount the selected pump assembly to an existing pipe system, which has a predetermined pipe layout.
As a result of needing to supply pump assemblies to fit multiple different pipe layouts, pump manufacturers design, manufacture and inventory many different types of pump assemblies, which is expensive for the pump manufacturers.

Embodiment Construction

[0016]FIG. 1 is an exploded perspective view of an exemplary horizontal, multistage pump assembly 10 arranged within a pump system 100 that includes a supply pipe 102 and a discharge pipe 104. The pump assembly 10 includes a pump motor 12 and a pump housing 14. In the illustrated embodiment, the pump housing 14 includes a cartridge 15 and a manifold or volute 16 that are separately provided from one another and coupled to one another. In an exemplary embodiment, the cartridge 15 includes a multistage pump stack having a plurality of pumping stages. The pump assembly 10 may be installed in an existing or new pipe system to the supply pipe 102 and the discharge pipe 104 for increasing the pressure and / or flow of water or another fluid within the pipe system.

[0017]In the illustrated embodiment, the pump assembly 10 represents a horizontal pump assembly that may be mounted to a base 18 via a plurality of supports or braces, such as motor supports 20, a cartridge support 22, and volute s...

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.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application relates to U.S. application Ser. No. 11 / 868,860 filed Oct. 8, 2007, the subject matter of which is herein incorporated by reference in its entirety.BACKGROUND OF THE INVENTION[0002]The subject matter herein relates generally to horizontal multistage pump assemblies, and more particularly, to adaptors for horizontal multistage pump assemblies.[0003]Pump assemblies are provided within pipe systems of residential, commercial or industrial facilities for increasing the pressure and flow of the fluid within the pipe system. The pump assembly is usually fitted to supply and discharge pipes of the pipe system to circulate the fluid under pressure. The typical pump assembly has an inlet that supplies fluid to the pump through a manifold having an impeller chamber, an impeller located in the chamber, a power head (e.g. motor and shaft) to drive the impeller, and a discharge that returns the fluid to the pipe system. The inlet is f...
