Abstract
A progressing cavity pump/motor includes an upper stator tube (), a lower stator tube (), a rotor () sitting between the upper and lower stator tubes, and a coupling assembly () interconnecting the stator tubes comprising an outer sleeve (), an inner sleeve () and a nut () for threaded engagement with at least one of the sleeves to bring a stop surface on the inner sleeve into mating engagement with the stop surface on the outer sleeve. The pump/motor is usually assembled in the field while maintaining precise axial and rotational positioning of the stator tubes.
