Abstract
A pump assembly includes a pump housing having a fluid inlet, a fluid outlet, and a fluid channel defined therebetween. The pump assembly also includes an impeller positioned within the fluid channel and configured to channel a fluid between the fluid inlet and the fluid outlet. The pump assembly also includes a motor assembly having a shaft coupled to the rear plate, wherein the shaft defines a first fluid cavity coupled in flow communication with an opening in the rear plate to enable fluid flow into the shaft. The motor assembly also includes a motor housing having a back plate positioned relative to the impeller rear plate to define a second fluid cavity therebetween. The motor assembly further includes a stator assembly coupled to the back plate and positioned opposite the second fluid cavity such that the fluid facilitates cooling the stator assembly.
