    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 translation: 电动泵（10）包括用于加压流体的泵头（22）和用于驱动泵头的电动机。 在泵头内部，两个对称泵区产生的径向力彼此平衡，以减少应力并提高效率。 高压流体离开泵并沿流经电机气隙的流动路径通过承载中空泵转子轴远端的端部轴承，并通过中空转子轴（44）返回泵头。 电机转子轴（44）相对于泵头可轴向移动，这有效地将电机转子浮在高压流体中。 马达定子隔板56可以阻止流体流入马达定子90，并且转子隔板112可以阻止流体流入马达转子。 转子屏障罐以这样的方式有效地附接到转子轴上，以加固轴并增加其抗弯曲性。 定子隔板的壁很薄并且在流体压力下膨胀以与定子叠片和电机端罩接触并且找到结构支撑。 通过在邻近泵头（22）的马达内放置一个热敏感开关（130），当检测到过热状态时关闭马达（14），检测马达内的过热状况以及泵头。

    Abstract: A moderately high pressure, sliding vane pump is fabricated from low modulus plastic by routing high pressure fluid away from the central pump perimeter and into a bearing gland chamber for discharge porting. Port fittings are push socket connections that are sealed by O-rings and held in place against fluid pressure ejection by a saddle plate that cross-pins to the port boss.
