This patent describes a matched pump and turbine motor set operating in the incompressible domain and developing a high power level comprising a pump which produces an output pressure that is inversely interdependent on its output flow and produces a maximum of output power as the product of its pressure and flow when its flow is constrained to pass through a predetermined optimum area. The turbine motor has a rotor of the impulse type and an inlet flow path for fluid entering the turbine motor. The flow path has an effective area normal to the entering flow sufficiently close in size to the optimal area that when pumping fluid through the turbine motor the pump is induced to operate substantially at its maximum output power level, and means coupling an inlet and an outlet of the pump and motor for fluid flow therebetween.
