Abstract
A centrifugal pump includes a selectable regenerative style pumping element, including a regenerative pump rotor and at least one side wall flow channel formed by a rotating disc. The regenerative pumping element is selectable between a first state in which the disc does not rotate with the impeller and a second state in which the disc rotates with the impeller.
