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.
