The corrosion resistance of the stainless-steel plunger pumps available from Cat Pumps has been
expanded with the introduction of the 3501 and 3511 models.
The new Cat Pumps corrosion-resistant high-pressure pump.
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
