CENTRIFUGAL PUMP ABSTRACT OF THE DISCLOSURE The invention relates to a centrifugal pump of the type adapted for use in pumping multiple phase liquids, i.e. liquids having entrained gas and liquids having both entrained gas and solids. The pump includes means for effecting an initial separation of gas from the liquid, as by centrifugal action, and a final separation by means of a unique pump-out mechanism disposed rearwardly of a shroud of an impeller of the pump and including pump-out vanes and a repeller shroud cooperating with the impeller shroud and pump-out vanes to define radially opening flow paths, wherein flow openings extend across the impeller shroud for flow communication with the radially opening flow paths. The mechanism may also include repeller vanes carried by the repeller shroud to extend rearwardly of pump-out vanes.
