product description

Pump valve sealing graphite ring is an important seal. It has become an irreplaceable component in the sealing field due to its unique physical and chemical properties.

Graphite ring uses graphite material as the matrix and has excellent self-lubricating properties. In the friction link, its use can effectively reduce the wear rate of the sealing surface. Even in the face of dry friction or insufficient lubrication, it can maintain stable sealing. It is particularly suitable for frequent start-stop or low-speed operation equipment.

Graphite sealing ring has wide temperature adaptability. It will not melt and deform when used at high temperatures. It can maintain toughness at low temperatures. Compared with rubber, plastic and other materials, graphite ring is more suitable for high-temperature steam, molten salt medium or deep fluid environment.

In addition, graphite sealing ring is very excellent in corrosion resistance. It is extremely inert to strong acids, strong alkalis and organic solvents. Its chemical stability far exceeds that of metal seals, and it can cope with complex media environments in chemical processes.

In addition to graphite processing, we also provide impregnation services, such as impregnated resin graphite rings. The impregnated graphite ring has a higher density, which can ensure the reliability of dynamic sealing.
