  • Gas tolerant subsea pump
    Patent number: 8393876
    Abstract: A combined canned motor-pump operates directly in the process fluid without the need for shaft seals or buffer or lubricating fluids. The pump incorporates an integral gas-separating system that includes gas separating hydraulics and a flow path that returns the gas to the main gas/oil separator. The gas-separating system includes a pump inlet for accepting incoming multiphase flow, at least one blade rotatable about the axis of rotation, an open annulus region for separating gas from liquid in the multiphase flow, at least one radial hole in the shaft for directing separated gas to the axial hole, and a pump outlet for discharging liquid from the pump.
