A success story: high-performance technology for extremely robust seal faces

The diamond thin-layer technology was developed in 2007 by EagleBurgmann together with the Fraunhofer Institute for Surface Engineering and Thin Films (IST).

The diamond layer has a thickness of up to 10 μm and is applied to the seal face under vacuum at temperatures of 2,000 °C (3,632 °F) by means of chemical vapor deposition (CVD). It is characterized by extreme hardness, high wear protection, excellent heat conductivity, maximum chemical resistance and low friction.

All in all, the best prerequisites for long operational performance. For years, DiamondFace coatings have proven themselves in pumps, agitators, and compressors in the oil & gas, chemical and pharmaceutical industries and in slurry applications.

Transferring technology for power station technology

In a joint project with the Technical University of Graz, Austria, the diamond technology was further developed for power station applications. Since 2010, endurance tests under scientific conditions prove the corrosion resistance of the DF-SA seals.
