The mechanical seal IN0340.8BQQVGG is a precision-engineered component designed for reliable shaft sealing in demanding industrial pump applications. This model belongs to the standardized IN9B/IN8B series, a comprehensive catalog of mechanical seals (каталог торцевих ущільнень) known for robust construction and consistent performance. Its design incorporates a press ring (тип з прижимним кольцом), ensuring secure installation and stable operation under varying pressure and rotational conditions.

Constructed for durability, the seal features stationary and rotating faces manufactured from silicon carbide (карбид кремния), a material renowned for exceptional hardness, excellent wear resistance, and superior chemical inertness. This pairing provides a highly reliable sealing interface with a long operational lifespan. The metal components are fabricated from AISI304 stainless steel, offering good corrosion resistance, while the elastomeric element utilizes NBR (Nitrile Butadiene Rubber), suitable for a wide range of fluids including oils, water, and many chemicals.

Critical dimensions of the mechanical seal (розміри торцевого ущільнення) are precisely defined to ensure correct fit and function. The seal is engineered for a shaft diameter (d1) of 34.9 mm. The external diameter of the fixed part (d7) is 60.33 mm, and the outer diameter of the moving part (d3) measures 61 mm. The overall seal length (L3) is 45 mm. These standardized dimensions facilitate straightforward selection and replacement from technical documentation. As a grade 8B seal, it meets specific performance and material specifications within its series.

The IN0340.8BQQVGG mechanical seal is suitable for applications in chemical processing, general industrial pumping, water treatment, and irrigation systems where reliable sealing of rotating shafts is paramount. Its balanced design and material selection aim to minimize leakage, reduce maintenance downtime, and extend the service intervals of pump equipment. For accurate selection, always verify the compatibility of seal materials with the specific fluid, temperature, and pressure conditions of the application, consulting the full technical specifications within the relevant catalog of mechanical seals.
