Abstract

A submersible pump housing with seal bleed ports is provided. In an implementation, a pump housing for electric submersible pumps (ESPs), such as a centrifugal ESP, has end seals that are located inside or further inboard toward the high thrust pressure generated by the pump, than the threaded ends of the pump housing. The inboard seals contain and seal off the pump pressure and spare the threaded regions that are more pressure-vulnerable from the pump's high pressure interior, thereby increasing the pressure rating of the entire housing. Leak ports or bleed ports are provided further outboard of the end seals to relieve fluid seeping from inside the submersible pump housing past each end seal. A plate may be added to direct small amounts of fluid escaping from the end seals away from the wellbore casing in which an ESP is situated.
