Graphite sealing ring

Vacuum pump graphite rotors and vanes have good self-lubrication and wear resistance and can work normally in dry-running state without additional lubricating oil or grease. Therefore, they can effectively avoid the contamination and damage to the vacuum pump caused by lubricating oil or grease. Meanwhile, they have good corrosion resistance and high temperature resistance, and can adapt to harsh working environments, so they are widely used in dry vacuum pumps.
