The mechanical seal IN0280.680W.QQVGG is a robust and precisely engineered sealing solution designed for demanding industrial applications. This model belongs to the comprehensive **каталог торцевих ущільнень** IN680W series, representing a standardized yet high-performance option for pump and rotating equipment maintenance. Its construction is defined by a metal bellows type, which provides superior axial flexibility and compensation for shaft endplay and misalignment, ensuring reliable long-term operation.

Critical **розміри торцевого ущільнення** are meticulously specified to guarantee correct installation and optimal function. The seal is engineered for a shaft diameter (d1) of 28 mm. The external diameter of the fixed part (d7) measures 48 mm, while the moving part features an outer diameter (d3) of 50 mm. The overall seal length (L3) is 46.5 mm. These dimensions are crucial for technicians when selecting a replacement from the catalog to ensure compatibility with existing gland and shaft configurations.

The material selection for the IN0280.680W.QQVGG underscores its suitability for challenging environments. 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, promoting extended service life and stable leakage control. The metal structural components are made from AISI 304 stainless steel, offering good corrosion resistance. The secondary sealing element utilizes VITON fluorocarbon elastomer, which provides excellent compatibility with a wide range of oils, fuels, and many aggressive chemicals, along with high-temperature stability.

As a key component within the **каталог торцевих ущільнень**, the 680W grade seal is engineered for general industrial service in centrifugal pumps, mixers, and compressors. Its metal bellows design eliminates the need for a dynamic O-ring, reducing hang-up and improving performance in applications with crystallizing or viscous media. The precise combination of durable materials and exacting dimensions makes the IN0280.680W.QQVGG a dependable choice for reducing downtime and maintenance costs, ensuring effective shaft sealing under varied operational conditions.
