The mechanical seal IN0180.502B.QQVGG is a high-performance bellows-type sealing solution engineered for demanding industrial applications. As part of the comprehensive **каталог торцевих ущільнень (catalog of mechanical seals)** for the IN502B series, this model is designed to ensure reliable operation in aggressive media and under challenging operational conditions. Its construction utilizes premium materials to guarantee longevity and consistent sealing integrity.

Key to its performance are the precisely defined **розміри торцевого ущільнення (mechanical seal dimensions)**. The seal is configured for a shaft diameter (d1) of 18 mm. The stationary part features an external diameter (d7) of 33 mm, while the rotating part has an outer diameter (d3) of 32 mm. The overall seal length (L3) is 24 mm. These standardized dimensions facilitate straightforward selection and replacement from the catalog, ensuring compatibility with a wide range of pump and mixer models.

The material specification underscores the seal's robustness. Both the stationary and rotating sealing faces are manufactured from silicon carbide (карбид кремния), a material renowned for its exceptional hardness, wear resistance, and chemical inertness. This pairing provides superior dry-running capabilities and excellent performance against abrasive particles. The metal structural components are made from AISI 304 stainless steel, offering good corrosion resistance. The critical bellows and secondary sealing element are composed of VITON fluorocarbon rubber, which ensures reliable elasticity and long-term stability when exposed to high temperatures, oils, fuels, and many aggressive chemicals.

As a **сильфонное (bellows-type)** seal, model IN0180.502B.QQVGG compensates for axial shaft movement, vibration, and minor misalignments automatically through its flexible metal bellows design. This eliminates the need for a secondary shaft seal like an O-ring, simplifying installation and enhancing reliability. The 502B seal grade indicates a specific design configuration optimized for balanced performance in standard industrial duties.

This mechanical seal is suitable for applications in chemical processing, petrochemical industries, refrigeration compressors, and general-purpose centrifugal pumps where leakage prevention is critical. Its precise engineering and high-quality material composition make it a dependable component for maintaining system efficiency and preventing environmental contamination or product loss.
