The B07 Mechanical Seal is a balanced metal bellows seal designed as a reliable replacement for TS 700 type seals. It offers a robust sealing solution for general industrial applications, combining durability with consistent performance.
With operating limits up to 2 MPa pressure, speeds up to 25 m/s, and a temperature range from -30°C to +200°C, the B07 is well-suited for medium-duty environments. Its metal bellows construction ensures flexibility to accommodate thermal expansion and shaft movement while maintaining sealing integrity.
The seal features high-quality materials such as silicon carbide, carbon, and stainless steel components, along with secondary sealing options including VITON and PTFE encapsulated rings, providing excellent resistance to corrosion, wear, and chemical exposure.
