High-pressure triplex piston pumps are applied in a variety of well drilling applications to drill using a foam and compressed air process. The high-pressure pump is used to inject a foam mix at low flow rates into the compressed air supply line. 

Also, when drilling consolidated rock with compressed air, clouds of dust can be blown out of the well hole. Pumping low-flow high-pressure water into the airline will effectively dampen dust, protecting the health of operators and the equipment. 

Cat Pumps triplex high-pressure piston pumps have been the pump of choice for well operators for over 35 years. With a variety of power sources such as electric, gas and diesel, our piston pumps have become the industry standard for water and foam injection applications worldwide.

With field-proven dependability in applications around the globe, Cat Pumps provides the best high-pressure pumps and systems for water and foam injection (well drilling) systems.
