A small high capacity centrifugal pump for the transfer of liquids is disclosed. The pump has a circular pump chamber, a hole (bored off center relative to the diameter of the pump chamber) for installation of the drive shaft component, the outlet and inlet nozzles of very large internal diameter. The impeller is a foraminous sleeve formed as a one piece casting of a width slightly less than the impeller's diameter. It is threaded at its inboard end for mounting onto the threaded end of the impeller mounting fixture, and are open at its opposite end, except for a narrow circular integral ring which serves as a sealing member between the rotating impeller and the stationary pump chamber wall.
