Applications:

The Cemented carbide mechanical seal ring can be divided into kinetic seal-ring and static seal-ring, and constitutes mechanic seal together with the spring, rubber seal-ring and steel jacket.

It will be used mainly for waste water pump, water discharge pump for mines, centrifugal pump, centrifuge, slag slurry pump and slurry abrasion and corrosion. The seal-ring will be installed on the pump body and rotating axle, and forms through the end face of the kinetic and static ring a liquid or gas seal.

Material advantage: the usage life of our all material is better than the silicon carbide.

The price of MG1 is similar with silicon carbide, but the transverse rupture strength is stronger, not easier to break in the working.
