  • Low maintenance costs thanks to its efficient design and all-stainless steel construction. Service intervals of up to 8,000 hours can be expected.
  • Low energy costs  due to its highly efficient axial piston design
  • Easy installation 
  • Fulfills the stringent hygiene requirements, VDI 6022, HACCP 
  • ISO 9001 and  ISO 14001

BACK TO ALL DANFOSS
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.
