Tungsten Carbide Seal Rings are used as Mechanical Seal faces in pumps, Compressors and Agitators. Used in Oil Refineries, Petrochemical plants, Fertilizer Plants, and Pharmaceutical Industries — developed to withstand high temperature, high pressure and highly corrosive chemical attack.
Excel Sealing Solution manufactures rings in various shapes as per customer requirements. Tungsten Carbide Rings are made with Cobalt or Nickel as binder material, replacing previously used Hardened Steel and Steel alloys in Indian Industries.
Standard WC-Co grade offering excellent hardness, toughness and wear resistance. Most widely used binder for mechanical seal applications in general industrial use.
WC-Ni grade provides superior corrosion resistance compared to cobalt binder — ideal for corrosive chemical and pharmaceutical environments.
