A motor and pump barrier fluids pressure regulation system for a subsea motor and pump module comprising a motor and a pump is disclosed. The regulation system comprises a motor barrier fluid circuit hydraulically separating the motor from the pump, and a pump barrier fluid circuit hydraulically separating an internal structure of the pump from a pumped medium, wherein the fluid flow and pressure in each of the motor barrier fluid circuit and the pump barrier fluid circuit are controlled by pressure controlled on/off valves arranged in each circuit, the pressure controlled on/off valves being individually controllable in response to a detected difference in pressure between the pumped medium, on a suction side of the pump or on a discharge side of the pump, and the fluid in the motor barrier fluid circuit and the pump barrier fluid circuit. |
