CAT plunger pumps are industry recognised triplex pumps designed for operation in extremely high-pressure applications up to 690bar. Therefore, the CAT high pressure plunger pump range is often a reliable solution when other pump types fail.

Due to the synchronised movement of the integrated plungers, CAT high pressure pumps benefit from a smooth and low pulsating flow. These triplex plunger pumps ensure that a constant volumetric flow is always delivered by taking in a fixed volume of liquid. This is attributed to the inlet stroke on the piston moving the set amount of liquid around and out of the pump. CAT pumps are also more efficient than similar types of triplex pumps, offering in some cases greater than a 50% improvement in energy consumption.

Popular applications for CAT triplex plunger pumps include water mist cooling, chemical injection, pressure cleaning, reverse osmosis and food processing. To select the CAT pump model that is most appropriate for your installation, you need to take consider several factors, including the liquid to be pumped, duty cycle, operating temperatures, drive, location and whether the area is classified as safe or hazardous.
