Simpler, more economical, longer lasting: DF-SA with DiamondFace technology for boiler feed water pumps

There is no chance of elec­tro­chem­i­cal cor­ro­sion with the di­a­mond-coated high-per­for­mance DF-SA seal. The tech­nol­ogy not only makes dosing systems su­per­flu­ous, but is also char­ac­ter­ized through out­stand­ing op­er­a­tional per­for­mance. DF-SA me­chan­i­cal seals are per­fectly co­or­di­nated to the powerful feed water pumps and avail­able for all fossil and nuclear power stations.

Within five years the DF-SA mechanical seals can save costs of up to 40 % and more.*

40,000 hours icon for EagleBurgmann DiamondFace technology, highlighting extended service life and long-term reliability in mechanical seal applications.

DF-SA mechanical seals reach operating periods of up to 40,000 hours and more. They therefore have the same maintenance intervals as pump bearings or balancing elements, for example.

No corrosion icon for EagleBurgmann DiamondFace technology, highlighting corrosion resistance and reliable performance in demanding mechanical seal applications.

Resistant against electrochemical corrosion in feed water pumps (electrical potential is removed over the seal faces).

No external cooling icon for EagleBurgmann DiamondFace technology, highlighting reduced cooling requirements and simplified operation in mechanical seal applications.

Cooling circuit no longer requires conditioning.

* Discreet: The calculation is based on a typical installation and operation of a feed water pump with mechanical seals with 140 mm (5.51") shaft diameter. The actual savings essentially depend on how the pump is operated. The statements made here indicate possible potentials through the use of mechanical seals with DiamondFace technology as compared to preceding installations at corresponding use and application.
