Abstract

Disclosed herein is a liquid pump for use with a fluid circulation system for a recreational water body. The liquid pump includes a strainer housing, a pump housing assembly secured to the strainer housing, and a lock ring fastened to the pump housing assembly. The pump housing assembly includes an outlet that is rotatable between a first position and a second position and further includes an annular protuberance defining an inlet. The strainer housing includes an outlet, and the annular protuberance extends through the outlet of the strainer housing into a chamber thereof. A clip is positioned within the chamber and releasably secures the annular protuberance so as to inhibit inadvertent disengagement of the strainer housing from the pump housing assembly.

1 . A liquid pump for use with a fluid circulation system for a recreational water body, comprising:
 a pump housing assembly that includes a casing; a casing cover forming a fluid chamber with said casing and having an inlet through which filtered fluid can flow; an outlet formed in said casing; an impeller positioned within said fluid chamber for pumping filtered liquid through said outlet; a lock ring securable to a motor and fastened to said casing such that said casing is rotatable between a first position, in which said outlet is arranged in a first orientation, and a second position, in which said outlet is arranged in a second orientation; fastening means for rotatably fastening said casing to said lock ring; and latching means for releasably latching said casing when said outlet is in said first and second orientations; and   a strainer housing having an inner surface which defines a filtering chamber, an inlet in communication with said filtering chamber for receiving liquid to be filtered, and an outlet for discharging filtered liquid from said filtering chamber to said inlet of said casing.
