Abstract
A submersible pumping system that is operable under hydrostatic pressure. The system suitably comprises a prime mover submersible within a first fluid; a pump means submersible within the first fluid and sealably coupled to the prime mover; and a fluid source in fluid communication with the prime mover, the fluid source providing a second fluid effective to act on the prime mover to power the pump means; wherein the second fluid is discharged in the first fluid after acting on the prime mover; and wherein the second fluid has a chemical composition substantially similar to the first fluid.
