High-pressure positive displacement pumps are the best choice for hydrostatic testing. With positive-displacement pumps, flow is constant regardless of system pressure, which means high-pressure can be achieved and maintained in a system. This pump characteristic is important for hydrostatic testing.

In hydrostatic testing, a component, vessel, or section of a pipe or line is subjected to a target pressure and held for a period of time based on the test or regulation parameters. Typical liquids used include water and hydraulic oil. High-pressure water is often the preferred medium due to its unique properties: it “leaks” more easily than oil and is more environmentally compatible. Hydrostatic testing is used to validate burst pressure ratings, identify and locate leaks, verify structural integrity, test for manufacturing imperfections, comply with safety regulations, and certify repair work.
Cat Pumps has been serving this market for many years with high-pressure pumps ranging to from 100 psi/6.9 bar to 10,000 psi/690 bar, with flow rates between 0.13 gpm/0.49 lpm and 240 gpm/908 lpm. To meet the demands of a wide variety of applications, pumps are available with brass, nickel aluminum bronze, 304 stainless, 316 stainless and duplex stainless steel manifolds. Cat Pumps also offers system design and fabrication services for custom pumping units, including variable frequency drives (VFD’s) . VFD’s are often used to modulate flow through motor speeds to maintain a set pressure, which is required in hydrostatic testing.

The durability and long-life of Cat Pumps products are key decision variables for designer and users of hydrostatic testing systems. Often, testing must be completed by established timetables. A reliable and always-ready high-pressure system is mandatory.  With field-proven dependability in applications around the globe, Cat Pumps provides the best value for high-pressure hydrostatic test pumps and systems.
