1. A pump assembly for a bathing unit system, the pump assembly comprising:
a. a motor housing holding an electric motor, the motor housing having a front end, a back end and a rotor shaft extending through the front end;
b. a wet-end housing having a water inlet port and a water outlet port in fluid communication with the water inlet port for circulating water through the wet-end housing in response to rotation of the rotor shaft;
c. a controller module including a circuit board including a controller for controlling operation of the electric motor;
d. a heat transfer interface positioned between the front end of the motor housing and the wet-end housing; and
e. a rim positioned proximate the front end of the motor housing and engaged with the heat transfer interface, the rim comprising a first partial rim member and a second partial rim member at least partially thermally insulated from the first partial rim member to at least partially thermally insulate the controller module from the motor housing, wherein:
(i) the first partial rim member extends about a periphery of the front end of the motor housing except for a portion of the periphery of the front end and wherein the first partial rim member cooperates with the heat transfer interface to establish a first thermal conduction path between the motor housing and the wet-end housing so that, in use, a portion of heat generated by the electric motor is absorbed by the heat transfer interface and is dissipated in water circulating through the wet-end housing, and
(ii) the second partial rim member fits in the portion of the periphery of the front end about the periphery of the front end of the motor housing and wherein the second partial rim member cooperates with the heat transfer interface to establish a second thermal conduction path between the controller module and the wet-end housing, so that, in use, a portion of heat generated by the controller module is absorbed by the heat transfer interface and is dissipated in the water circulating through the wet-end housing.
