The IN0200.109QQVGG is a high-performance mechanical seal from the IN109 series, designed for demanding industrial applications requiring reliable shaft sealing. This bellows-type (сильфонное) seal is engineered to provide a durable and effective barrier against fluid leakage in pumps, mixers, and other rotary equipment. Its construction utilizes premium materials to ensure longevity and stable operation under a range of operational conditions.

Key to its performance is the robust material specification. Both the fixed and moving seal faces are manufactured from silicon carbide (карбид кремния), a material renowned for its exceptional hardness, wear resistance, and chemical inertness. This pairing ensures minimal friction and a long service life, even in abrasive or corrosive media. The metallic structural components are made from AISI 304 stainless steel, offering excellent corrosion resistance and structural integrity. The secondary sealing element is a VITON elastomer, known for its superior compatibility with a wide spectrum of chemicals, oils, and high-temperature fluids.

Precise dimensional compatibility is critical for proper installation and function. This seal is configured for a shaft diameter (d1) of 20 mm. The external diameter of the fixed part (d7) measures 35 mm, with an overall seal length (L3) of 21.5 mm. These exact **розміри торцевого ущільнення** must be verified against the equipment specifications to guarantee a correct fit. The model designation, IN0200.109QQVGG, and the seal grade 109 provide the necessary identifiers for precise selection and replacement from any comprehensive **каталог торцевих ущільнень**.

As part of the CATALOG OF MECHANICAL SEALS / IN109 category, this unit represents a standardized solution for maintenance and OEM applications. The bellows design accommodates minor axial shaft movements and misalignments, enhancing operational reliability. When selecting this mechanical seal, it is imperative to confirm the chemical compatibility of all wetted materials—particularly the VITON elastomer and silicon carbide faces—with the specific process fluid, as well as the operational pressure and temperature ranges of the application.
