Hydrostatic Test Unit Operation

The Cat Pumps HTU comprises of a high pressure pump and motor/gear-motor assembly. An inbuilt water supply tank feeds the high pressure pump which in turn feeds a high pressure distribution manifold, a pressure regulator and a large easy to read calibrated pressure gauge. The high pressure distribution manifold has four outlets with varying ports that can be used for supplying the item on test and any extra pressure monitoring devices. The HTU has an inbuilt pressure relief valve that will prevent the unit from achieving pressures in excess of the system design. An incorporated pressure release valve allows the pressurised water to be released back to the supply tank after a hydrostatic test has been completed.
