Abstract: A system and methodology are provided for enhancing the life and usefulness of a thrust bearing assembly in a submersible pumping system component. The technique utilizes a thrust runner positioned adjacent a thrust bearing in the submersible pumping system component. The thrust runner is rotated relative to the thrust bearing via a shaft. Gas that may accumulate in a lower region beneath the thrust runner is vented through a passageway from the lower region to an upper region above the thrust runner. The gas is vented to help maintain a hydrodynamic fluid film between the thrust runner and the thrust bearing.

Abstract: A protector for an electric submersible pump includes a plurality of chambers, with adjacent or consecutive pairs of chambers coupled, e.g., fluidly coupled, via a series or parallel body. The body defines two separate hydraulic circuits, which allows for the inclusion of a shaft seal, even when the body couples consecutive chambers in a parallel configuration or couples to a thrust bearing chamber. The shaft tube circuit can include a compensator and/or a relief valve.
