A method and apparatus for mounting an electric water pump adjacent the exterior wall of a bathtub or the like. The pump is fitted with mounting brackets having hooks and a separate mounting stand is provided to received those hooks and thus secure the pump at a desired location. The stand comprises an integral bottom plate and vertical plate preferably at right angles to one another. The vertical plate has numerous hook hanger slots located virtually from the bottom to the top of the plate and provided in numerous columns and rows to receive the hooks on the pump mounting plates. On the illustrated embodiment of the vertical plate there are 90 such hook hanger slots distributed in two spaced sections. A first section receives two hooks from one of the pump mounting brackets and a second section receives two hooks from another of the pump mounting brackets. The spacing between sections corresponds to the spacing between brackets and the spacing between hook hanger slots in each section corresponds to the spacing between hooks on each bracket. The pump may, consequently, be mounted at multiple height locations along a substantial extent of the vertical plate. The multiple columns of slots provide suitable mounting for pumps having different spacing between mounting brackets.

Method and apparatus for mounting an electric water pump

A centrifugal pump for use in whirlpool bath systems has an offset inlet chamber configured to provide a smooth transition from inlet to impeller which is suitable for one-step injection molding using two opposed molding cores that may be removed from the inlet in opposite directions. The chamber has a double 'D' profile with opposite flattened side surfaces. The cross-sectional area of the chamber decreases progressively between a larger offset inlet aperture and a smaller, centered entrance to the impeller. This configuration improves pumping efficiency while reducing noise.

Suction cover for a whirlpool bath

A suction assembly employs an air induction tube to induct air into the recirculating water pump to cause the pump to cease pumping operation when the front face of the assembly is blocked. The induction tube is connected to a bleed path formed between the induction tube and a surrounding coaxial face tube extended into the assembly from the front face. When the face is blocked by hair or the like, water in the induction tube bleeds into the main chamber of the assembly and empties the induction tube. Air is then pulled into the pump, causing the pump to lose prime thereby reducing pump pressure to zero and allowing the hair or other blocking material to be removed. In a preferred embodiment, the induction tube is connected to the air inlet of at least one venturi-type hydromassage jet assembly. The suction assembly employs a spring-loaded induction stem which bears compressively against the interior face of the suction cover, thereby permitting use of conventional suction covers.
