Custom-made:
There is a big choice of sizes and types of the seal-rings, we can also recommend, design, develop, produce the products according to the drawings and requirements of the customers.

Applications:
The cemented carbide seal-ring can be divided into both of the kinetic seal-ring and static seal-ring, and constitutes mechanic seal together with the spring, rubber seal-ring and steel jecket.
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 the kinetc and static ring a liquid or gas seal.
