Silicon Carbide (SiC) wear parts, including seal faces, bushings, sleeves, and washers, are manufactured using high-quality materials. The available material grades include Reaction Bonded Silicon Carbide (RBSiC) and Sintered Silicon Carbide (SSiC). Additionally, we can provide Silicon Carbide with Carbon Graphite Impregnation for specialized applications.
Our products are widely used in pump seals and other mechanical sealing systems due to their excellent wear resistance, thermal stability, and durability. Below are the technical specifications of our materials:
