Silicon carbide seal faces for mechanical …

In mining appliions, portable submersible pumps are usually preferred.The large, main pumps in mines are usually made of cast iron. Mechanical seals have to be resistant to corrosion and friction so pressureless sintered silicon carbide/ssic should be taken into consideration as the working faces and rings and the metal parts should be at least 316L instead of 304

SEALING SENSE

mechanical seal hard face. However, another popular composite is graphite-loaded silicon carbide. It is most commonly used in split seal designs, since the grain structure facilitates re-assely of split seal faces. Typically, a sintered silicon carbide is the matrix so the material has superior oxidation resistance even though it con-
