ABSTRACT:
The centrifugal pump includes a separable, multipartite impeller assembly and preferably incorporates a shock-absorbent shaft support that is tolerant of impeller vibrations or minor imbalances in the impeller assembly. The multipartite impeller assembly comprises an impeller portion, a wet-end magnetic coupler, and a radial bearing. The impeller portion and the wet-end magnetic coupler are secured together by a snap-fit joint, which is reinforced by a radial bearing adjacent to the snap-fit joint. The shaft support has an encapsulation junction which secures braces to a peripheral base.
