Reduce emissions with compact high-pressure pumps

Danfoss PAHT G high-pressure pumps are designed for ultra-pure water. PAHT G pumps are developed especially for various gas turbine applications, such as the reduction of NOx emissions in diesel engines, inlet fogging, and wet compression. Lubrication of the moving parts is provided by the water itself. PAHT G 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 they are suitable for water with inlet pressure boosted from the supply tank. There is no need for cooling circuits due to a very high mechanical efficiency.

All PAHT G pumps are available with ATEX certification.

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

  • Compact design. Easy installation

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