Abstract
A fluid pump includes a pump housing having a housing cavity with an inlet and an outlet. A diffuser is located within the housing cavity, and includes a portion that is attached to the housing. The diffuser has a diffuser cavity, in which a stator assembly and canister are located. The canister provides a seal where it contacts the diffuser; this isolates the stator assembly from the fluid. The stator assembly provides a magnetic field which drives a rotor assembly. The rotor assembly rotates an impeller, which pumps the fluid from the inlet to the outlet.
