A pump is disclosed, including a motor and a pump housing, for pumping mixed gas and liquid. The pump includes two intermeshed screw members for providing progressive cavities for transporting mixed fluids, within a pumping cavity, from a suction passage to a discharge reservoir of the pump housing. It further uses pumped product to provide cooling and lubrication to the motor and to bearings and timing gears of the screw members. By using pumped product for lubrication and cooling, the need for seals is eliminated, thereby reducing the need for maintenance. This makes the pump package advantageous for subsea deployment for use in pumping nearly depleted wells which may be manifolded together to provide adequate product flow.
