2. 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:
