The mechanical seal IN0280.8BQQVGG is a precision-engineered component designed for reliable shaft sealing in demanding industrial applications. This model belongs to the comprehensive CATALOG OF MECHANICAL SEALS / IN9B/IN8B series, representing a robust design characterized by its inclusion of a gland plate (с прижимным кольцом). Its construction ensures optimal performance in pumps, mixers, and compressors handling a wide range of fluids.

Key specifications define its precise application fit and durability. The seal is configured for a shaft diameter d1 of 28.6 mm. Critical **розміри торцевого ущільнення** include an external diameter of the fixed part d7 at 50.8 mm and an outer diameter of the moving part d3 of 51.5 mm, with an overall seal length L3 of 37 mm. The material selection underscores its capability for challenging environments. Both the fixed and moving seal faces are manufactured from карбид кремния (silicon carbide), a material renowned for exceptional hardness, wear resistance, and chemical inertness. The metal components utilize AISI304 stainless steel for structural integrity and corrosion resistance, while the elastomeric element is made from NBR (Nitrile Butadiene Rubber), offering reliable flexibility and resistance to oils and fuels.

The IN0280.8BQQVGG is classified under seal grade 8B, indicating a specific balance of performance characteristics suitable for medium-duty applications. The integration of a gland plate enhances stability and simplifies installation, ensuring proper alignment and clamping force. When consulting the **каталог торцевих ущільнень**, this model stands out for its clear dimensional data and material transparency, allowing for accurate selection and replacement. Its design prioritizes long service life, minimal leakage, and maintenance reduction in systems where sealing integrity is paramount. This mechanical seal is an essential component for engineers and maintenance specialists seeking a proven, specification-driven solution for rotational equipment.
