Classification: CPC F | IPC F

Claim 0:
1. A pump assembly for a bathing unit system, the pump assembly comprising:
a. controller module including a circuit board mounted controller for controlling operations of the pump assembly;
b. a motor housing holding an electric motor, the motor housing having a front end and a back end, wherein the motor housing comprises a flange member forming a rim about the front end of the motor housing, wherein the rim formed by the flange member includes a first partial rim member and a second partial rim member distinct from the first partial rim member, wherein the second partial rim member includes:
i. a heat sink portion having a controller-facing side configured to establish a thermal coupling with the controller module; and
ii. a motor-housing-facing side machined to form a thermal separation gap between the motor-housing-facing side and an outer surface of the motor housing to at least partially thermally insulate the controller module from the motor housing;

c. a wet-end housing adjacent the front end of the motor housing, the 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; and
d. a heat transfer interface positioned between the controller module and the wet-end housing and configured to engage the second partial rim member of the flange member, wherein the heat transfer interface is configured for cooperating with the second partial rim member to establish a 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.
