Mechanical seals that are diamond-coated for reslience

These mechanical seals feature diamond-coated faces, which produce an extremely resilient surface with desirable friction and wear characteristics. Beneficial in services requiring protection from slurry, dry-running conditions or chemical corrosion, the coated seals offer improved reliability in poor-lubricity liquids, such as hot water. These seals are also suited for very aggressive liquid service, such as with acids, caustics and alkaline materials. The diamond-coated faces allow operation against all common mating-face materials including, carbon, silicon carbide and tungsten carbide, as well as providing resistance to abrasive particle damage. — Flowserve Corp., Irving, Tex.
