WB2 Series Type B (convex Ring)

Corrosive media, shaft friction and uneven pressure often cause seal leakage and frequent replacement on chemical production equipment. Our WB2 Series Type B (convex ring) addresses these common industrial pain points, adopting pressure-free silicon carbide sealing ring type B convex ring as the core friction pair, classified as premium corrosion-resistant sealing parts for severe chemical working conditions. Made of high-density sintered silicon carbide, this series boasts outstanding chemical stability to resist strong acids, alkalis and organic solvents, far more durable than ordinary graphite and metal seals. Its precision-machined convex structure evenly spreads contact pressure, removes local stress concentration and minimizes wear during long-term continuous operation. It is universally applicable to chemical compressor sealing and stirring equipment sealing, well suited for various chemical compressors, reaction stirring kettles and corrosive fluid processing facilities.…
