The trap tank protects the vacuum pump by collecting potential vapor droplets. Once vacuum has been established, the pump is turned off and the system, vented to atmospheric pressure. This causes the liquid in the feed tank to invade the entire system. Finally, a high-pressure pump pressurizes the saturation liquid up to 2,000 psi, via transfer vessel in to . . This pressure should be sustained for at least four hours to guarantee maximum core saturation. This is confirmed by a stable reading on the gauge. Optional : Automated controls integrated system with computer. Easy for end user to operate pneumatic valves, operate the vacuum and high-pressure pumps and run automatic saturation cycles.
