The mechanical seal IN0120.560С.BQVGG is a high-performance single-spring bellows seal designed for reliable shaft sealing in centrifugal pumps, mixers, and other rotary equipment. As part of the comprehensive **каталог торцевих ущільнень** for the IN560C/INBIA series, this model is engineered for durability and precise dimensional compatibility. Its construction is defined by a robust material combination, ensuring stable operation in a wide range of industrial fluids, including water, mild chemicals, and oils.

Key technical **розміри торцевого ущільнення** are critical for correct installation and function. The seal is configured for a shaft diameter (d1) of 12 mm. The external diameter of the fixed part (d7) is 23 mm, while the outer diameter of the moving part (d3) measures 22.5 mm. The overall seal length (L3) is 23.9 mm. These precise dimensions guarantee a proper fit within the seal chamber, preventing misalignment and ensuring optimal sealing face contact.

The material specification of the IN0120.560С.BQVGG underscores its application-oriented design. The primary sealing face of the fixed part is manufactured from silicon carbide (карбид кремния), a material renowned for its exceptional hardness, wear resistance, and chemical inertness. The mating rotating face is made from graphite, providing excellent self-lubricating properties and a reliable running-in surface. The metal structural components, including the spring housing, are constructed from corrosion-resistant AISI304 stainless steel, offering strength and longevity. The flexible bellows element is made from NBR (Nitrile rubber), which provides reliable elasticity and resistance to oils and aliphatic hydrocarbons within its temperature range.

This **сильфонное** (bellows-type) design eliminates the need for a dynamic O-ring on the shaft, reducing friction and hang-up issues, particularly in applications with minor shaft wear or crystallization. The seal grade 560C indicates a standardized configuration within the catalog, facilitating easy identification and replacement. The mechanical seal IN0120.560С.BQVGG is suitable for general industrial service where reliable sealing of water, coolants, and other non-aggressive media is required. Its precise engineering and material selection ensure extended service life, reduced maintenance downtime, and prevention of fluid leakage in demanding rotary applications.
