Mechanical seal IN0300.90BQQVGG

The IN0300.90BQQVGG is a robust mechanical face seal engineered for reliable shaft sealing in demanding industrial applications. This model belongs to the comprehensive IN90B series within the broader **каталог торцевих ущільнень**, offering a standardized solution for pumps, mixers, and compressors. Its design incorporates a clamping ring (прижимное кольцо), ensuring secure installation and stable operation under variable pressure and rotational conditions.

Constructed for durability and chemical resistance, the seal utilizes silicon carbide (карбид кремния) for both the stationary and rotating faces. This material pairing provides exceptional hardness, excellent wear resistance, and reliable performance in abrasive or corrosive media. The metal components are fabricated from AISI304 stainless steel, offering good general corrosion resistance. The secondary sealing element is made from NBR (Nitrile) rubber, ensuring effective elastomeric performance across a wide range of temperatures and compatible fluids.

Precise **розміри торцевого ущільнення** are critical for proper fit and function. The IN0300.90BQQVGG is designed for a shaft diameter (d1) of 30 mm. The external diameter of the stationary part (d7) is 45 mm, while the outer diameter of the moving part (d3) measures 44 mm. The overall seal length (L3) is 35.5 mm. These dimensions ensure compatibility with standard housing geometries and facilitate straightforward replacement. The seal is classified under grade 90B, indicating its specific configuration and application profile within the sealing system catalog.

This mechanical seal is suitable for a variety of industrial sectors, including chemical processing, water treatment, and general industrial machinery where preventing leakage along rotating shafts is paramount. Its balanced design and material selection contribute to extended service life, reduced maintenance downtime, and enhanced operational safety. When selecting a seal from the **каталог торцевих ущільнень**, the IN0300.90BQQVGG represents a dependable choice for applications requiring a 30 mm shaft seal with robust construction and proven performance characteristics.
