Coating technology ensures maximum operational reliability for compressor seals

 



Innovative DiamondFaces coating, as used on liquid-lubricated seals, is said to have an excellent track record even under extreme conditions. This technology has now been enhanced for use on the broad silicon-carbide seal faces on compressor seals. Designed primarily for non-contact operation, contact for sustained periods can make the sliding faces of DGS seals subject to wear. This can ultimately damage the sealing faces, causing seal failure, which, in turn, leads to compressor downtime.

Operational performance is now achieved by depositing a fully continuous layer of crystalline diamond with a precisely defined thickness on the structured mating surfaces of gas seals. The chemical bond between the diamond and the silicon carbide creates an extremely rugged coating that does not impair the lift-off capabilities of the seal faces. This reduces the risk of compressor seal damage or failure during turning, ratcheting, frequent coast-down intervals or sub-optimal compressor-operating conditions. EagleBurgmann Germany GmbH & Co. KG
