The mechanical seal IN0250.8UQQVGG is a precision-engineered component designed for reliable shaft sealing in demanding industrial applications. This model belongs to the comprehensive CATALOG OF MECHANICAL SEALS / IN9U/IN8U series, representing a robust design with a clamping ring (с прижимным кольцом). Its construction ensures optimal performance in pumps, mixers, and compressors where fluid containment under varying pressures is critical.

Key specifications define its precise application fit. The seal is configured for a shaft diameter (d1) of 42850.041666667 mm. Its compact axial length (L3) is 25.4 mm. The external diameter of the fixed part (d7) measures 41.28 mm, while the outer diameter of the moving part (d3) is 40.3 mm. These точные розміри торцевого ущільнення are crucial for correct installation and housing compatibility. The seal grade 8U indicates a specific configuration of materials and design for defined operational parameters.

Material selection is paramount for durability and chemical resistance. Both the fixed and moving sealing faces are manufactured from карбид кремния (silicon carbide), a premium material offering exceptional hardness, wear resistance, and compatibility with a wide range of aggressive and abrasive media. The metal structural components are made from AISI304 stainless steel, providing excellent corrosion resistance and structural integrity. The secondary sealing element utilizes NBR (Nitrile Butadiene Rubber), a versatile elastomer suitable for applications involving oils, water, and many common industrial fluids.

The inclusion of a clamping ring enhances the assembly's stability and simplifies installation, ensuring proper alignment and face loading. When consulting the каталог торцевих ущільнень for a suitable model, the IN0250.8UQQVGG stands out for applications requiring a reliable seal with silicon carbide faces in a standard 8U configuration. Its design prioritizes long service life, minimal maintenance, and consistent sealing performance, making it a dependable choice for engineers and maintenance specialists seeking a proven mechanical sealing solution.
