The MB-B01 Mechanical Seal is a versatile metal bellows seal designed to provide flexible performance across different industrial requirements. It features a dual operating range, allowing it to function efficiently under both standard and extended pressure and temperature conditions.
With pressure capabilities up to 2.5 MPa and up to 4 MPa in extended configurations, speeds up to 25 m/s, and temperature ranges from -30°C to +200°C or extended up to -80°C to +350°C, the TSMB-B01 adapts to a wide variety of applications.
Its elastomer-free bellows structure combined with an encapsulated PTFE secondary seal ensures reliable sealing, chemical resistance, and durability. Built with high-performance materials such as silicon carbide, carbon, ceramic, and advanced alloys, the MB-B01 offers long service life and stable operation in both moderate and demanding environments.
