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.
Claims16
A magnetically driven unit of a fluid pump assembly, comprising:
- a housing comprising a base and a nozzle;
- a rotator at least partially contained in the housing, the rotator comprising a magnet constructed and arranged to be magnetically coupled to and rotationally driven by a magnet of a drive unit;
- a shaft operatively connected to the rotator;
- a blade operatively coupled with the shaft;
- a magnet cover fixed to the base to enclose the rotator so that the magnet being disposed between the base and the magnet cover;
- and
- an axle concentrically surrounded by the shaft, the axle comprising a flanged base contacting a surface of the base.
