Claim Text:
1. A pumping apparatus comprising: a housing having an inlet at a first end and an outlet at an opposite second end; a stator including a plurality of windings and defining an opening and supported by the housing; an encapsulation including a first end cap and a second end cap formed into the stator such that the encapsulation fills some of the spaces within the stator to hold the plurality of windings in a desired position, the encapsulation and the stator cooperating to at least partially define an encapsulated stator; a pressure plate including diffuser vanes formed as part of the pressure plate, the pressure plate formed as one continuous homogeneous component of the first end cap of the encapsulation; a rotor positioned at least partially within the opening and rotatable with respect to the stator; a first bearing directly supported by the encapsulation; a second bearing directly supported by the encapsulation, the first bearing and the second bearing cooperating to support the rotor for rotation; and an impeller coupled to the rotor and cooperating with the pressure plate and the housing to pump a fluid from the inlet to the outlet in response to rotation of the rotor, the fluid in direct contact with a portion of the encapsulation as it flows between the inlet and the outlet.
