Abstract: In accordance with some embodiments of the present disclosure, a thrust washer and a diffuser for use in a downhole electrical submersible pump are disclosed. The pump may include a shaft and a motor communicatively coupled to the shaft. The motor may be operable to rotate the shaft. The pump may further include an impeller coupled to the shaft. The impeller may contain a balance ring, a balance hole, and a hub. The pump may further include a diffuser disposed adjacent to the impeller. The pump may further include a thrust washer coupled to the impeller. The thrust washer may be located between the balance ring and the hub without blocking the balance hole to allow fluid flow through the impeller and the diffuser. The pump may further include a discharge operable to direct fluid flow out of the multi-stage electrical submersible pump.

Abstract: In accordance with embodiments of the present disclosure, a electrical submersible pump includes a pump housing, a shaft extending at least partially through the pump housing and adapted to be driven by a submersible motor, an impeller attached to the shaft and having an impeller passage for fluid to flow therethrough, and a diffuser that is stationary relative to the pump housing and having a diffuser passage, wherein the diffuser is disposed corresponding to the impeller to form a pump stage such that fluid can flow between the impeller passage and the diffuser passage. The electrical submersible pump also includes a labyrinth seal formed between the impeller and the diffuser, wherein the labyrinth seal selectively seals the impeller passage from a cavity formed between the impeller and the diffuser to maintain the impeller in a floating condition relative to the diffuser.
