Lepu PTFE Bellow Seal WB3 25MM Teflon Bellow Mechanical Seal Supplier

The PTFE Bellow Seal is a specialized type of mechanical seal used in various industries to prevent leakage and maintain the integrity of equipment. Made from polytetrafluoroethylene (PTFE), this seal consists of a series of convoluted bellows that provide exceptional flexibility and resilience. The PTFE material offers excellent chemical resistance, making it ideal for applications involving corrosive fluids or gases. Moreover, its low friction coefficient ensures smooth operation, minimizing wear on rotating shafts. The bellow design allows for axial movement while maintaining a tight seal, compensating for thermal expansion and vibration that can occur during operation. With its unique properties and construction, the PTFE Bellow Seal provides reliable sealing performance even under demanding conditions encountered in pumps, compressors, mixers, and other industrial machinery.

Replacement of John Crane WB3, PTFE bellows design, outside mounted, used in strong corrosive chemical occasions. The WB3 series uses PTFE(teflon) bellows and adopts a multi-spring structure design. The WB2 type spring is protected by a perfluoroethylene cover. 

This mechanical seal is widely used in petroleum, chemical industry, oil refining, papermaking, pharmaceutical, electric power, automobile and other industries.

In order to keep high level ability against corrosive medium, Lepu seal use 100% virgin Teflon(PTFE) raw material for the ptfe bellows, skilled workers machined the ptfe bellows seal WB3 by high precision CNC machine.
