Highly reliable pumps with low risk of contamination

Danfoss PAHT high-pressure pumps are designed for ultra-pure water. PAHT pumps are developed for cleaning applications in the manufacturing of electronic parts (LCD and LED) and parts in the automobile industry, as well as in adiabatic cooling- and humidification systems. Lubrication of the moving parts is provided by the water itself. PAHT pumps are the lightest and most compact pumps in the industry and can be installed horizontally or vertically. 

They are powered by electric motors or combustion engines and are suitable for boosted inlet pressure and water supply from tank. There is no need for cooling circuits due to very high mechanical efficiency.

Features and benefits

Zero risk of oil contamination thanks to the pump’s ultra-clean technology where no oil is needed

Low maintenance costs thanks to its efficient design and stainless steel construction. Service intervals up to 8,000 hours can be expected

Low energy costs due to its highly efficient axial piston design

Easy installation

Fulfils the stringent hygiene requirements, VDI 6022, HACCP

ISO 9001, ISO 14001 and ATEX certified (API available on request)
