  • Stage pump having composite components
    Publication number: 20050074330
    Abstract: A system and method is provided for pumping fluid. A pump incorporates composite components that provide a high degree of formability while maintaining wear resistance for use in potentially abrasive environments. The composite components may comprise one or more impellers and/or one or more diffusers.

  • System and method for removing solid particulates from a pumped wellbore fluid
    Patent number: 6698521
    Abstract: A system for removing solid particulates from a production fluid. The system includes a solid separator to remove the solid particulates from the production fluid to reduce pump component wear. The system is disposed in a wellbore such that wellbore fluids are drawn into the solids separator before entering the submersible pump. Solid particulates are separated from the fluid that flows through the solids separator before entering the submersible pump. The solid particulates are routed past the submersible pump. The solid particulates may be reinjected into the fluid discharged from the pump.
    Type: Grant
