Sintered Silicon Carbide Mechanical Seal Ring

Pressureless sintered of silicon carbide in high purity and ultrafine silicon carbide powder as raw material, add a small amount of sintering additives at 2100 °C high temperature sintering vacuum environment, the products obtained almost entirely density, excellent mechanical properties of ceramic materials. It can be used in the high concentrations of acid or alkali medium. This material is widely application in mechanical seal face, valve bearing and oil, chemical industry, aerospace, automotive and other fields.

They have the property of excellent resistant-corrosion, high mechanical strength, high thermal conductivity, good self-lubrication, used as seal faces, bearings and tubes in spacecraft, machinery, metallurgy, printing and dyeing, food stuff, pharmaceutical, auto industry and so on. When the SiC faces are combined with graphite faces the friction is the smallest and they can be made into mechanical seals which are able to work in highest working requirements.

The mechanical seal ring is made of rotating seal ring, stationary seal ring, spring, rubber seal ring and steel jacket. The main material can chose SSiC, RBSiC, TC, graphite or ceramics for seal ring.

It will be used mainly for waste water pump, water discharge pump for the mines, centrifugal pump, centrifuge, slag slurry pump and slurry pump in the adverse working conditions of high speed rotation, sand flush abrasion and corrosion. The seal ring will be installed on the pump body and rotating axle, and forms through the end face of rotating and stationary ring a liquid or gas seal.

Rotating and stationary ring types with groove against turning, with rubber seal ring, with teeth, balancing and non-balancing, etc. We produce the products according to the drawings and requirements of our customers, we also recommend, design and develop new types against the customer needs.
