The mechanical seal IN0220.FBC.BVPGG is a bellows-type sealing solution engineered for reliable operation in rotary shaft applications. This model belongs to the comprehensive **каталог торцевих ущільнень** series IN1/INFBC, representing a standardized design for ease of selection and replacement. Its construction is defined by precise **розміри торцевого ущільнення**, ensuring a correct fit and optimal performance.

Key dimensional parameters include a shaft diameter (d1) of 22 mm. The seal features a moving part with an outer diameter (d3) of 35 mm and a fixed part with an external diameter (d7) of 36 mm. The overall seal length (L3) is 34 mm. These carefully calibrated dimensions guarantee proper installation and interface within the sealing chamber, contributing to the unit's stability and leak-tight integrity.

Material selection for the IN0220.FBC.BVPGG is critical for its durability and chemical compatibility. The primary sealing face is formed by a graphite moving part, known for its excellent self-lubricating properties and wear resistance. It runs against a fixed ceramic ring, providing a hard, corrosion-resistant counterface for effective sealing. The bellows and other metallic components are manufactured from AISI304 stainless steel, offering good general corrosion resistance. The secondary elastomeric seal is made from NBR (Nitrile rubber), suitable for a wide range of fluids including oils, water, and many chemicals within its temperature range.

As a member of the FBC seal grade, this model is designed for general industrial service. The bellows-type (сильфонное) design eliminates the need for a dynamic O-ring, reducing friction and hang-up, which is particularly advantageous in applications with slight axial shaft movement or where crystallization of pumped media is a concern. Typical applications include centrifugal pumps, mixers, and compressors handling water, coolants, light oils, and other non-aggressive fluids.

When consulting the **каталог торцевих ущільнень**, the IN0220.FBC.BVPGG is identified by its specific combination of **розміри торцевого ущільнення** and material configuration. This precise specification allows for accurate cross-referencing and procurement, minimizing downtime during maintenance. Its standardized design ensures reliable sealing performance in standard pump cavities designed for this seal type.
