  • Integrated electric submersible pumping system with electromagnetically driven impeller
    Patent number: 11643911
    Abstract: An electric submersible pumping system is constructed with an outer housing which contains an integrated pump and motor. The pump may comprise an impeller disposed within a stator of the motor to form an integrated pump and the motor. An electric submersible pumping system includes a stator having a passage extending longitudinally through the stator. A plurality of stages, including impellers and diffusers, are disposed within the passage.

  • ELECTRICAL SUBMERSIBLE PUMPING SYSTEMS
    Publication number: 20220178376
    Abstract: Systems and methods facilitate pumping of various fluids such as well fluids. An electric submersible pumping system is constructed with an outer housing that contains an integrated pump and motor. The pump may include an impeller disposed within a stator of the motor. The integration of the pump and the motor enables elimination of various components of traditional electric submersible pumping systems to thus provide a simpler and more compact system for pumping fluids.
