Abstract: An electric submersible pump device having a motor part, a pump part, and a protector part. The protector part includes redundant shaft seal parts.

Abstract: A submersible pump can include a male part that includes an outer diameter; a female part that includes an inner diameter; an elastomeric seal element disposed between the male part and the female part; and a non-elastomeric seal element disposed between the male part and the female part. Various other apparatuses, systems, methods, etc., are also disclosed.

Abstract: A system and methodology facilitate connection between components of an electric submersible pumping system. The technique utilizes at least one connector designed to connect a first component to a second component of an electric submersible pumping system. The connector is designed as a flangeless connector which secures engagement of the two components without relative rotation between the first component and the second component. Additional flangeless connectors may be positioned between other pairs of components to provide the enhanced connection throughout the electric submersible pumping system.

Abstract: According to one or more aspects of the present disclosure, a motor protector comprises a housing defining a compensator chamber; a compensator disposed in the housing having a motor fluid end in fluid communication with a motor fluid and a well fluid end, the compensator axially moveable relative to the housing in response to the expansion and contraction of the motor fluid; and a port formed through the housing to provide fluid communication from exterior of the housing to the well fluid end of the compensator. The compensator may be one selected from the group of a bellows and a plunger.
