    Abstract: A system for accommodating thermal expansion of a pump housing. The system includes a pump having an external housing, and a mounting structure for mounting the pump. Contacting members are disposed intermediate the mounting structure and the pump for allowing one-dimensional movement of the external housing along a longitudinal axis of the external housing. Alternatively, bearing members are positioned to support the pump in the mounting structure, while allowing a thermal distortion of the housing.

    Abstract: A submersible centrifugal pump has a downward thrust washer of reduced diameter. The pump has a housing containing a plurality of stages of impellers and diffusers. Each impeller is rotated by a shaft for discharging fluid upward and outward into an intake of a diffuser. A counterbore is formed in the upper end of a bore that passes axially through the diffuser. An upward facing shoulder is located at the lower end of the counterbore. A thrust washer is located on the shoulder. An extension sleeve extends downward from the hub of each impeller into the counterbore of the diffuser of a next lower stage. Downward thrust on the impeller is transmitted through the extension sleeve to the thrust washer.

    Abstract: A latching mechanism for selectively disengaging an upper pump from a motor in an ESP. The latching mechanism comprises barbs formed on an upper end of an upper shaft that are engaged by a tool to lift the upper shaft until a lower end of the upper shaft disengages from an upper end of a motor shaft. When the upper pump is disengaged from the motor shaft, only a lower pump is driven by the motor and flow of well fluid is circulated past the disengaged upper pump via a bypass line. The upper pump shaft may reengage the motor shaft if additional lift is required.

    Abstract: A system allows the pumping of viscous fluids from a wellbore. The system includes a submergible pump and a pump intake through which a fluid may be drawn. A submergible electric motor powers the submergible pump, and a heater is connected in the pumping system to heat the wellbore fluid. Additionally, a combination of heaters may be employed to heat the desired production fluid both externally to the pumping system and internally to the pumping system.
