Product Description
Silicon carbide mechanical seal rings are hard ceramic sealing components that help control fluid leakage in pumps and other rotating equipment.
The ceramic ring forms either the rotating or stationary face of a mechanical seal. Its precision-finished end face works with a mating ring across a narrow sealing gap to control leakage. It is a component of the seal assembly, not a complete mechanical seal.
High hardness and wear resistance help preserve the working face during sliding service. Thermal conductivity helps carry heat away from the sealing interface, while corrosion resistance supports use in many chemical-processing and water-treatment pump applications.
