WATER-COOLED PUMP ASSEMBLY FOR BATHING UNIT SYSTEM AND PUMP ASSEMBLY FOR BATHING UNIT SYSTEM WITH MOUNTING BRACKETS

A pump assembly is presented including a motor housing holding a motor, a wet-end housing and a heat transfer interface positioned between a front end of the motor housing and the wet-end housing. The heat transfer interface establishes a first thermal conduction path between the motor housing and the wet-end housing so that a portion of heat generated by the motor is absorbed by the heat transfer interface and a second thermal conduction path between a controller module of the pump assembly and the wet-end housing so that heat generated by the controller module is also absorbed by the heat transfer interface. The pump assembly may include a first and second partial rim members for establishing the first and second thermal conduction paths. Mounting brackets at different radial locations about the motor housing may allow the pump assembly to be mounted in different orientations.
