Diamonds Are A Seal’s Best Friend

Flowserve signs collaborative agreement with Advanced Diamond Technologies; utilizing diamond coating in many applications

Posted on April 23, 2013

Flowserve Corp., which produces engineered and industrial pumps, seals and valves as well as a range of related flow management services, announced it has signed a collaborative agreement with Advanced Diamond Technologies Inc. (ADT) to become the exclusive developer and supplier of diamond coated hard faces for its mechanical seals.

When applied to Flowserve base materials, the ultrananocrystalline-structured diamond (UNCD) coating developed by ADT produces an exceptionally hard surface with significantly improved friction and wear characteristics, the company said. This is particularly beneficial in services requiring protection from slurry, dry running conditions and resistance to chemical corrosion.

ADT said it is a leader in developing and applying diamond films for electronic, mechanical, industrial and biomedical applications and offers several families of high-performance products that exploit the unsurpassed characteristics of diamond.

Flowserve and ADT, a spinoff company from the U.S. Department of Energy's Argonne National Laboratory, have worked together since the 1980s to develop, refine and perfect diamond coating for mechanical seal faces.
