Abstract:
A submersible pumping system for use downhole, wherein the system includes a first pump, a second pump, a recirculation coupling between the first and second pumps, and a recirculation line for directing cooling flow across the pump motor. The pumps and coupling are independent modular items connected together. Optionally, a multi-stage pump may be retrofitted with the coupling for creating a cooling flow.
