Introduction |
The Danfoss range of PAHT 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.

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

Application examples |
• |
High-pressure cleaning with ultra-pure |
|
|
|
water, as used in the manufacturing of |
|
|
|
flat-panel displays and many other |
|
|
|
electronic products. |
|
|
• |
High-pressure cleaning with ultra-pure |
|
|
|
water, as used in the manufacturing of |
|
|
|
parts for the automobile industry. |
|
|
• |
Adiabatic cooling systems to replace or |
|
|
|
supplement standard A/C systems in server |
|
|
|
rooms and factories. |
•Humidification in office buildings, electronic component manufacturing, dairies, greenhouses, etc.
•Dust suppression and odor control systems, for example in paper, textile and wood production.
•Reduction of NOx emissions in diesel engines and gas turbines.
•Gas turbine by inlet fogging and fuel wash systems.
