Abstract

A pump for pumping a multiphase fluid includes a housing and a rotor with an outer surface. A plurality of inducer vanes are attached to the rotor hub, each having a leading edge and a trailing edge where the leading edge of one inducer vane overlaps the trailing edge of an adjacent inducer vane by a first overlap angle. A plurality of impeller vanes are also attached to the hub. The impeller vanes each have a leading edge and a trailing edge where the leading edge of one impeller vane overlaps the trailing edge of an adjacent impeller vane by a second overlap angle larger than the first overlap angle. The pump includes a rotor flow channel extending between the hub outer surface and the housing inner surface. The rotor flow channel has an inlet area and an outlet area, whereby the outlet area is smaller than the inlet area.
