Cat Pumps' has expanded corrosion resistance to its high-pressure 3507 and 3517 triplex positive displacement plunger pumps. The 316 stainless-steel models 3501 and 3511 plunger pumps meet the requirements of specialized industrial applications where corrosive and aggressive liquids need to be pumped.
These triplex high-pressure pumps are suited for 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 pumps also have a flushed option with models 3501C and 3511C, providing cooling with hi-temperature liquids and added lubrication with low-lubricity liquids such as DI water or CO2.
The continuous-duty triplex design can reduce pulsation, increase energy efficiency and extend pump life. The pump also features 316SS liquid-end construction with optional NBR, FPM, EPDM and PTFE elastomers that meet the demands of a wide range of aggressive liquids. The 3501 or 3511 are available as part of a custom pumping system.
