The IN0280.1.BVPGG is a bellows-type mechanical seal designed for reliable shaft sealing in a variety of industrial rotary equipment. This model belongs to the comprehensive **каталог торцевих ущільнень** (catalog of mechanical seals) under the category CATALOG OF MECHANICAL SEALS / IN1/INFBC, representing a standardized solution for specific dimensional and operational requirements. Its construction ensures effective containment of fluids and prevention of leaks in pumps, mixers, and similar apparatus.

Engineered with precision, the seal's key **розміри торцевого ущільнення** (mechanical seal dimensions) are critical for correct installation and performance. It is designed for a shaft diameter (d1) of 28.58 mm. The external diameter of the fixed part (d7) is 44.45 mm, while the moving part has an outer diameter (d3) of 41.3 mm. The overall seal length (L3) is 41.28 mm. These exacting dimensions guarantee proper fitment within the seal chamber and secure operation without interference.

The IN0280.1.BVPGG utilizes a robust material combination tailored for durability and chemical compatibility. The primary sealing face of the fixed part is manufactured from керамика (ceramic), offering exceptional hardness and wear resistance. The corresponding moving part face is made from графит (graphite), providing excellent self-lubricating properties and a reliable running surface. The metal structural components are fabricated from AISI304 stainless steel, ensuring corrosion resistance in many common industrial environments. The flexible bellows element is made from NBR (Nitrile rubber), a material chosen for its good resistance to oils, fuels, and a wide range of fluids. This seal is classified with a seal grade of 1, indicating its standard duty design.

As a сильфонное (bellows-type) seal, the IN0280.1.BVPGG design incorporates a flexible metal bellows that serves multiple functions: it transmits spring force to the sealing faces, accommodates axial shaft movement and wear, and eliminates the need for a dynamic elastomeric gasket, which can be beneficial in certain fluid services. This configuration enhances reliability in applications with potential shaft runout or vibration.

This mechanical seal is suitable for general industrial applications involving water, light oils, coolants, and other non-aggressive media where its material construction is compatible. Its standardized dimensions and proven design make it a readily available component for maintenance and repair operations, supporting the reduction of downtime and operational costs. When selecting a seal, always verify the compatibility of the NBR elastomer and other materials with the specific process fluid, as well as the pressure and temperature parameters of the application.
