ABSTRACT:
A floating impeller assembly for use with an electromagnetic stator unit includes a stationary shaft with a magnetic rotor rotationally mounted on the shaft. An impeller unit is rotationally mounted on the shaft and a unitary retaining and clutch mechanism between the magnetic rotor and the impeller unit drives the impeller unit by means of rotation of the magnetic rotor. The magnetic rotor and the impeller float on the shaft facilitating reducing the noise, friction and wear, heretofore, present in prior art units. The floating impeller assembly is used within an aquarium filter for drawing water from the aquarium into the aquarium filter for filtration and discharge back into the aquarium tank.
