Abstract
A submersible pump system with a pump, motor and compensator assembly. In one embodiment, the compensator assembly is made up of multiple elastomeric compensators and a housing. The elastomeric compensators, which are made up of an engaging end, a floating end and a series of alternating crests and grooves, may contain motor cooling liquid. The crests and grooves extend along the compensator's longitudinal axis. The compensators possess a degree of elasticity sufficient for a width of at least one of the respective grooves to expand and contract along with the motor cooling liquid. The crests slide along an interior wall of the housing, while the floating end moves within the housing in cooperation with expansion and contraction of the width of at least one of the grooves.
