Abstract
A high pressure transfer motor-pump providing for pumping a wide range of process fluids (e.g. chemicals, multiphase fluids, and particle polluted fluids) between intake and outlet ports at high pressure with little to zero leak to the environment and little to no contamination between the pumped process fluid and the driving hydraulic fluid. In accordance to an embodiment a high pressure transfer motor-pump includes a process fluid path extending between an inlet port and an outlet port, a cylinder having a barrier separating a hydraulic fluid path from the process fluid path, a motor coupled across a dynamic seal to a hydraulic pump to manipulate the cylinder barrier by circulating a hydraulic fluid through the hydraulic supply fluid path and a housing pressurized at an inlet pressure of the inlet port and encapsulating the motor, the pump, the dynamic seal and the hydraulic fluid.
