Abstract

A well pump assembly has a tubular junction having a main tube and a bypass tube. An electric motor and seal section hang below the tubular junction in the main tube. The motor is powered by a power cable that extends alongside the tubing to the surface. The motor has an upper end with a drive shaft coupling. The pump for the motor is lowered through the production tubing on a wireline, wire rope or coiled tubing. The pump has a lower end which has a driven shaft coupling that makes up in stabbing engagement with the drive shaft coupling when the pump reaches the motor. The driven shaft coupling includes a guide that slides into a coupling housing. Orientating keys orient the guide and lock it from rotation. The bypass tube of the tubular junction may receive workover tools that are diverted by a wireline tool.
