LEPU SEAL  offers various material combinations for mechanical seal faces, elastomers, and metal components to meet different operating conditions. Common seal face materials include carbon graphite, silicon carbide (SSiC/RBSiC), tungsten carbide, and ceramic, while available elastomer materials include EPDM, FKM (Viton), NBR, FFKM, and PTFE.

The material selection depends on factors such as the sealing medium, temperature, pressure, corrosion level, abrasion resistance, and equipment operating conditions. For example, silicon carbide and tungsten carbide are commonly selected for applications requiring high wear resistance, while different elastomer options are chosen according to chemical compatibility.

For metal components, LEPU SEAL  commonly uses materials such as SS304 and SS316, with other alloy materials available according to customer requirements.

With experience in customized mechanical seal manufacturing since 1998, LEPU SEAL  can help customers select suitable material combinations for pump mechanical seals, cartridge seals, dry gas seals, and other sealing solutions.

LEPU SEAL  provides a wide range of mechanical seal solutions to meet different pump, compressor, and industrial equipment requirements. Our main products include pump mechanical seals, cartridge mechanical seals, dry gas seals, mixer and agitator seals, OEM replacement seals, and mechanical seal spare parts.
