Mechanical seal IN0180.120HBVPGG

The mechanical seal IN0180.120HBVPGG is a high-performance component engineered for reliable shaft sealing in rotary equipment such as pumps, mixers, and compressors. As part of the standardized IN120HB series featured in comprehensive mechanical seal catalogs, this model offers a proven design for demanding industrial applications. Its construction ensures effective containment of process fluids, prevention of leaks, and protection of equipment from abrasive media.

This seal is characterized by its robust material composition and precise dimensional specifications. The primary sealing face is formed by a stationary ceramic ring, providing exceptional hardness and wear resistance against abrasive particles. The mating rotating face is manufactured from high-grade graphite, ensuring a smooth, low-friction running surface and reliable sealing contact. The metal components, including the spring housing, are constructed from corrosion-resistant AISI304 stainless steel, guaranteeing durability in various chemical environments. The elastomeric element is made from NBR (Nitrile Butadiene Rubber), which offers excellent resistance to oils, fuels, and a wide range of fluids.

Critical **розміри торцевого ущільнення** are precisely defined for correct installation and interchangeability. The seal is designed for a shaft diameter (d1) of 18 mm. The external diameter of the fixed part (d7) is 33 mm, while the outer diameter of the moving part (d3) measures 36 mm. The overall seal length (L3) is 32.5 mm. These standardized dimensions facilitate easy selection and replacement from any detailed **каталог торцевих ущільнень**. The actuation mechanism utilizes a cylindrical spring design, which provides consistent and uniform closing force across the sealing faces, ensuring stable performance under variable pressure conditions and shaft runout.

The IN0180.120HBVPGG mechanical seal is classified under seal grade 120HB, indicating its specific performance envelope and compatibility. Its material synergy—combining ceramic, graphite, stainless steel, and NBR—makes it suitable for a broad spectrum of applications involving water, mild chemicals, oils, and other non-aggressive media. The precise engineering of all components ensures long service life, reduced maintenance downtime, and enhanced operational safety for fluid handling systems.
