Diamond Coated Silicon Carbide Seal Face Material Solution for Challenging Applications, offered by Flowserve

Flowserve offers Diamond Coated Silicon Carbide Faces material solution for challenging applications. Ultrananocrystalline diamond (UNCD) coatings provide materials properties and performance advancement over all other seal face materials. In the past, external clean, cool fluid was used to lubricate seal faces or dual seals operating on clean barrier fluid. Now, the solution  is to use Diamond Coated Silicon Carbide Faced Seal (UNCD) and let the process fluid itself lubricate the seal even with challenging applications.

  • Benefits include:
    • Lowest friction seal face for cool running
    • Maximum abrasion resistance
    • Highest chemical resistance
    • High wear resistance
    • Use the “challenging” process fluid to lubricate the seal without damage
