HTU for Cyclic Pressure Testing Application

PUMPS
The Department of Civil and Structural
Engineering at The University of Sheffield Case Study Application were looking Specifications for a complete pump , motor ,
HTU E22488 and reservoir unit that was able to deliver the Cat Pumps Pump pressure Model : and 5CP41110CSS flowrate required for their cyclic pressure testing experiment . Pressure :
200 bar After a short search online , they discovered
Flow :
6.8 l / min
through the Cat Pumps ( U . K .) website that the Fluid : Cat Pumps Water Hydrostatic Test Unit ( HTU ) was the

The HTU from Cat Pumps is a robust compact mobile highpressure system utilising the highly reliable and long-lived Cat Pumps high-pressure pump and motor / gearbox assembly . An inbuilt 50 litre water supply tank feeds the high-pressure pump , which in turn feeds a high-pressure distribution manifold , which incorporates a pressure regulator and an easy-toread calibrated pressure gauge . The HTU has an inbuilt pressure relief valve that will prevent the unit from achieving pressures exceeding the system design . An incorporated pressure release valve allows the pressurised water to be released back to the supply tank after a hydrostatic pressure test has been completed . The HTU benefits from corrosion resistant wetted components and hoses . Its low noise operation makes it practical in most settings . It is highly reliable and low energy consuming . A great feature for the HTU is that it benefits from having an easy to service pump , which is backed by availability of replacement parts and oil , as well as relevant technical service information , helping to minimise system down time .
