    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 submergible, centrifugal pump utilizes an improved bushing system for absorbing downthrust at each stage of the pump. The centrifugal pump is a multi-stage pump having a plurality of impellers keyed to a rotatable shaft. Diffusers cooperate with the impellers to conduct the pumped fluid upwardly from one impeller to the next. The improved support system comprises simple diffuser bushings that are generally cylindrical in shape, and relatively inexpensive to manufacture. Each diffuser bushing is disposed between a diffuser and the next upwardly sequential impeller to support that impeller with respect to the downthrust created during pumping.

    Abstract: A submersible well pump assembly include a rotary pump driven by an electrical motor. A seal section operably connects between the motor and the pump for reducing a pressure differential between motor oil in the motor and well fluid surrounding the pump assembly. The pump assembly contains a sealed fluid. A sensor mounted to the well pump assembly detects contamination of the sealed fluid by well fluid encroaching into contact with the sealed fluid. The sensor may be mounted in the motor or the seal section to detect well fluid contamination of motor oil. The sensor may be mounted in a secondary pump that has that has temporary barriers to block the entry of well fluid into a buffer fluid contained in the secondary pump while the secondary pump is in a storage condition within a well.
