<p>A motor and pump barrier fluids pressure regulation system for a subsea motor and pump module is disclosed. The system comprises a motor barrier fluid circuit hydraulically separating the motor from the pump, and a pump barrier fluid circuit hydraulically separating the internal structure of the pump from the pumped medium, wherein the fluid flow and pressure in each of barrier fluid circuits is managed via pressure controlled on/off valves (10, 22; 14, 26) arranged in each circuit, the on/off valves being individually controllable in response to detected difference in pressure between the medium, on a suction side or on a discharge side of the pump, and fluid in the motor and pump barrier fluid circuits.</p> |
