Possessing independently developed ultra-high pressure equipment and ultra-high pressure sealing technology.

Combined seal layout effectively improves the life of the main seal. The main seal is arranged in a coaxial combination with an independent compensation function. Multiple wear-resistant carbon fibers are distributed axially, and the friction pair gap is stable. The structure is designed with leakage collection channels to extend the maintenance cycle of the hydraulic cylinder. The dustproof device isolates external pollution and ensures the safety of the seal ring.
