Abstract
A regenerative pump includes a housing defining a cavity having a fluid inlet arrangement and fluid outlet arrangement, and a channel having an open volume extending between the fluid inlet arrangement and the fluid outlet arrangement. A rotatable shaft extends into the housing. An impeller is mounted to the shaft within the cavity and has a plurality of vanes spaced circumferentially around the axis and opening into the channel. An arm arrangement at least partially defines walls of the channel. The arm arrangement is radially movable to vary the volume of the channel. Enlarging the volume of the channel inhibits regenerative circulatory flow during pumping and limits the pressure generated.
