Contents sealing ISSN 1350-4789 April 2011 www.sealingtechnology.info TECHNOLOGY E agleBurgmann Germany GmbH & Co Kg's DiamondFaces coating technology has been enhanced, enabling it to be used on the broad silicon-carbide faces of compressor seals.
The company says the enhancement ensures maximum operational reliability and performance under all compressor operating conditions in which the sliding faces of DGS seals might come into contact with each other.
Practical experience has shown that difficult operating states, such as turning, ratcheting and frequent coast-down intervals, during which the compressor runs for hours, days or even months at a time -at speeds below the seal face lift-off threshold or beyond the operating limits of today's gas seal technology -are not at all uncommon. Because the sliding faces on DGS seals are designed primarily for non-contact operation, contact for sustained periods can make them subject to wear. This can ultimately damage the sealing faces, causing seal failure which, in turn, leads to compressor down time.
Operational reliability and performance can be achieved by depositing a fully con-
