ABSTRACT:
The multipartite impeller assembly includes an impeller portion, a magnetic coupler, a snap-fit connector, and a radial bearing. The impeller portion and the magnetic coupler have complementary polygonal shapes which can be interlocked. The impeller portion and the magnetic coupler are secured together by a snap-fit connector, which is reinforced by a radial bearing adjacent to the snap-fit connector. The radial bearing prevents radial movement of the snap-fit connector or snap-fit joint, which could otherwise tend to release the snap-fit joint.
