Abstract
In a submersible deep well pump unit, a plastic fluid intake base coupling the motor to the pump is placed in axial compression over its entire length by means of overlapping bolts respectively connecting the base to the motor and the pump, resulting in a low cost, corrosion and impact resistant pump-motor base.
