Abstract
A fluid pump assembly is provided. The pump has a pair of units magnetically coupled to each other. The first unit contains a drive motor and a magnetic assembly. The second unit contains a magnetic assembly and a blade of a propeller/impeller for imparting movement to a fluid. As the first unit is activated by the drive motor, a magnetic flux is created which in turn rotates the magnetic assembly in the second unit, driving the blade.

- and
- a pump housing comprising a base and a nozzle, the nozzle having a base section connecting to the base, an end section, and a central section extending between the base section and the end section;
- a rotator at least partially contained in the pump housing, the rotator comprising a magnet constructed and arranged to be magnetically coupled to and rotationally driven by a drive unit magnet;
- a shaft operatively connected to the rotator;
- a blade operatively coupled with the shaft;
- a magnet cover cooperating with the base to enclose the rotator;
- and
- an axle concentrically surrounded by the shaft, wherein the end section contains a top wall and arms projecting from the top wall to a central hub, the arms allow fluid to flow therebetween and the central hub forms an upper constraint to receive a top portion of the axle.
