Mechanical Seal Manufacturers Wholesale Sintered Silicon Signet Tungsten Carbide Rings
Tungsten carbide seal ring
Tungsten Carbide Seal Rings are used as Mechanical Seal faces in pumps, Compressors and Agitators. These are used in Oil Refineries, Petrochemical plants, Fertilizer Plants, and Drugs/Pharmaceutical Industries.
Tungsten Carbide Rings are generally made with Cobalt as binder material. Nickel bonded Rings also can be supplied.
In various sizes and designs and with close dimensional tolerance for use as an integral part of mechanical seals in general utility pumps and chemical pumps. RCT tungsten carbide seal ring are used as the wear face of most mechanical seals for the sealing of fluids in all industries.
Application
1. All kind of mechanical shaft seals
