Mechanical Seals MG12 MB2 | Elastomer Bellow | SIC/SIC/VIT | Shaft 12-100mm

The MG12and MB2 series represent a premium range of elastomer bellow mechanical seals, engineered for reliability and durability in a wide array of industrial pumping applications. Designed to fit shaft sizes from 12mm to 100mm, these versatile seals provide a robust sealing solution for water pumps, chemical processors, and general rotary shaft equipment.

Constructed with high-quality Silicon Carbide (SIC) stationary and rotating faces, these seals offer exceptional hardness and thermal conductivity. This SIC/SIC combination ensures outstanding wear resistance, even when handling abrasive media or operating under dry running conditions. The seal faces are meticulously lapped to provide an ultra-flat sealing plane, minimizing leakage and maximizing long-term performance.

A key feature of the MG12 design is the elastomer bellow. Made from Viton (FKM), this bellow offers excellent chemical resistance and high-temperature stability, making it suitable for aggressive fluids and demanding thermal environments. Unlike spring-based seals, the bellow construction compensates for shaft vibration, misalignment, and axial movement without the risk of clogging or fatigue, ensuring consistent seal integrity.

Ideal for use in centrifugal pumps, mixers, and compressors, these mechanical seals are direct replacements for industry-standard types. They provide a cost-effective, high-performance solution that reduces maintenance downtime and extends equipment life. Trust the MG12 and MB2 series for leak-free operation and superior engineering in critical applications.
