High Pressure Pumps Pumps for Gas Turbines Type PAHT G

The Danfoss range of PAHT and PAHT G high-pressure pumps is specifically designed for use with technical water such as:
Ultra-pure water that has undergone multiple reverse osmosis processes
De-ionized water
Demineralized water

Danfoss PAHT pumps are positive displacement pumps, with axial pistons that move a fixed amount of water in each cycle. Flow is proportional to the number of input shaft revolutions (rpm). Unlike centrifugal pumps, they produce the same flow at a given speed independently of no matter what the discharge pressure.
The range of PAHT G pumps is based on the standard PAHT pump series. The PAHT G pumps are made with extra coatings that reduce the wear of the pump. This coating is particularly important for pumps used in gas turbine applications or other similar applications where the wear of the pumps is higher due to the ultra-pure water quality.

Benefits:
• Zero risk of lubricant contamination: - Oil lubricants are replaced with the pumped medium, water, so there is no contamination risk from the pump.
• Low maintenance costs: - Efficient design and all-stainless steel construction ensure exceptionally long lifetime. When Danfoss specifications are met, service intervals of up to 8,000 hours can be expected. Service is easy, and can be carried out on site due to the simple design and few parts.
• Low energy costs: - The highly efficient axial piston design provides the lowest energy consump¬tion of any comparable pump on the market.
• Easy installation:
- The lightest and most compact design available.
- Pump can be installed horizontally or vertically.
- No pulsation dampeners necessary due to extremely low-pressure pulsation.
- Powered by electric motors or combus¬tion engines.
- Suitable for both boosted inlet pressure and water supply from a tank.
- No need for cooling circuits due to very high mechanical efficiency.
• Certified quality:
- Fulfils the stringent hygiene require¬ments, VDI 6022, HACCP.
- Certificates: ISO 9001, ISO 14001
ATEX available on PAHT G, API available on request
