Abstract: A motor pump (10) includes a pump head (22) for pressurizing a fluid and an electric motor for driving the pump head. Within the pump head, radial forces produced in two symmetrical pumping zones are balanced against each other to reduce stress and increase efficiency. High pressure fluid exits the pump and follow a flowpath through the motor air gap, through an end bearing carrying a distal end of a hollow pump rotor shaft, and returning to the pump head by way of the hollow rotor shaft (44) . The motor rotor shaft (44) is axially movable with respect to the pump head, which effectively floats the motor rotor in high pressure fluid. A motor stator barrier (56) can inhibits fluid flow into the motor stator (90) , and a rotor barrier (112) can inhibits fluid flow into the motor rotor. The rotor barrier can is efficiently attached to the rotor shaft in such a way as to stiffen the shaft and increase its bending resistance. The walls of the stator barrier can are thin and expand under fluid pressure to make contact with and find structural support from the stator laminations and motor endshield. Overheat conditions within the motor, as well as the pump head, are detected by positioning a heat sensing switch (130) within the motor adjacent the pump head (22) to shut down the motor (14) when an overheat condition is detected.

Abstract: A method of making a pump housing that is net-molded and immediately assumes its final shape and design specification without requiring more than de minimis secondary machining processes. The method utilizes molds and cores configured such that none of the fluid ports of the housing produced using the molds and cores have any intersecting geometry. The net-molded pump housing may also include a cross-tube insert providing flow communication between a fluid inlet port and a pressure relief port.

The pump assembly also includes a distal bearing member having first and second sides and a second side, a plurality of inlet orifices, and a cavity formed in the second side. A first cam ring, having an elliptical interior opening, is disposed within the pump housing adjacent the distal bearing member. A rotor is disposed within the opening in the first cam ring. This rotor has first and second sides, a cavity in the first side, and a plurality of radial slots for sliding vanes. The vane pump assembly also includes a second cam ring, having an elliptical shape, disposed in the cavities formed in the distal bearing member second side and the rotor first side. In addition, the vane pump assembly includes a proximate bearing member disposed within the pump housing adjacent the first cam ring and having a plurality of outlet orifices.
