The mechanical seal IN0220.8BQQVGG is a precision-engineered component designed for reliable shaft sealing in demanding industrial pump applications. This model belongs to the comprehensive **каталог торцевих ущільнень (catalog of mechanical seals)** series IN9B/IN8B, specifically within the 8B seal grade category, indicating its construction with a press ring (прижимным кольцом) for secure installation and stable operation.

Constructed for durability and chemical resistance, the seal utilizes silicon carbide (карбид кремния) for both the stationary and rotating faces. This material pairing ensures exceptional wear resistance, low friction, and reliable performance when handling abrasive media or in high-temperature conditions. The metal structural components are manufactured from AISI304 stainless steel, providing robust mechanical strength and good corrosion resistance. The secondary sealing element is made from NBR (Nitrile Butadiene Rubber), a versatile elastomer offering a solid balance of oil and abrasion resistance.

Critical **розміри торцевого ущільнення (dimensions of the mechanical seal)** are precisely defined to ensure correct fit and function. The seal is engineered for a nominal shaft diameter (d1) of 22.2 mm. The external diameter of the stationary part (d7) is 41.28 mm, while the outer diameter of the moving part (d3) measures 40.3 mm. The overall seal length (L3) is 33 mm. These exacting dimensions are essential for proper selection from the catalog and successful integration into the specific equipment.

The IN0220.8BQQVGG mechanical seal is suitable for a wide range of centrifugal pumps, mixers, and other rotating equipment used in chemical processing, water treatment, and general industrial services. Its design with a press ring facilitates straightforward mounting and axial adjustment, contributing to easier maintenance and replacement procedures. By effectively preventing fluid leakage along the shaft, this seal enhances equipment reliability, reduces downtime, and supports operational safety and environmental compliance.
