The 316 Stainless Steel models 3501 and 3511 provide expanded corrosion resistance to the 3507 and 3517 triplex positive displacement plunger pumps.

The new 3501 and 3511 stainless steel plunger pumps from Cat Pumps meet the requirements of specialized industrial applications where corrosive and aggressive liquids need to be pumped. The triplex high pressure pumps are ideally suited to applications such as hydrostatic pressure testing of vessels and pipes, flushing through small instrument lines, enhanced oil recovery, saltwater desalination and high pressure chemical dosing and injecting.

The stainless steel plunger 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 DI water or CO2. Features of the plunger pumps include a rugged continuous-duty triplex design which provides low pulsation, energy efficiency and long life; a 316SS liquid-end construction with optional NBR, FPM, EPDM and PTFE elastomers which meet the demands of a wide range of aggressive liquids; and the 3501 or 3511 are available as part of a custom pumping system including safety valves which provide a system designed for applications with short lead times.
