These triplex positive-displacement high-pressure pumps are ideally suited to applications such as seawater desalination, hydrostatic pressure-testing of vessels and pipes, flushing through small instrument lines, enhanced oil recovery and high-pressure chemical dosing and injecting providing both high efficiency and long life, says Cat Pumps. Their 316SS liquid-end construction with optional NBR, FPM, EPDM and PTFE elastomers meets the demands of a wide range of aggressive liquids

The pumps also have a flushed option with models 3501C and 3511C, providing cooling with hi-temp liquids and added lubrication with low lubricity liquids such as deionized water or CO2 .
