Abstract
A rotary axial flow pump comprising an internal pump member; an outer pump member concentric and coaxial with the inner pump member; helical vanes located around the outer periphery of the inner pump member in the axial direction; helical vanes located around the inner surface of the outer pump member in axial direction, the vanes being on the inner member in the opposite direction to the vanes on the outer member; the inner and outer members being adapted for relative rotation about their common axis for pumping liquid in the axial direction between the vanes.
