The mechanical seal IN0280.1155BVPGG is a precision-engineered component designed for reliable shaft sealing in a wide range of industrial rotary equipment. As part of the comprehensive **каталог торцевих ущільнень (catalog of mechanical seals)**, specifically the IN1155 series, this model represents a standardized solution for pumps, mixers, and compressors. Its construction is defined by a conical spring type, which ensures consistent face loading and stable performance under variable operational conditions.

Key specifications, or **розміри торцевого ущільнення (dimensions of the mechanical seal)**, are critical for proper selection and installation. This seal is engineered for a shaft diameter (d1) of 28 mm. The external diameter of the fixed part (d7) measures 43.3 mm, while the outer diameter of the moving part (d3) is 46 mm. The overall seal length (L3) is 30 mm. These precise dimensions guarantee compatibility with standard housing bores and facilitate straightforward integration into existing systems, minimizing downtime during maintenance or replacement.

The material composition of the IN0280.1155BVPGG is selected for durability and chemical resistance. The primary sealing faces consist of a graphite fixed part and a ceramic moving part, a classic pairing that offers excellent wear characteristics, low friction, and reliable operation with various compatible fluids. The metal components are fabricated from AISI304 stainless steel, providing robust corrosion resistance. The secondary sealing element is made from NBR (Nitrile Butadiene Rubber), a versatile elastomer suitable for applications involving oils, water, and many other media within its temperature range. The seal is classified under grade 1155, indicating its specific design configuration within the catalog.

This mechanical seal is suitable for applications where preventing leakage along rotating shafts is paramount. Its conical spring design is particularly effective in maintaining seal face closure despite minor shaft runout or end-play. Engineers and maintenance professionals can confidently specify the IN0280.1155BVPGG from the **каталог торцевих ущільнень** for OEM assembly or as a reliable spare part, relying on its standardized **розміри торцевого ущільнення** and proven material combination to ensure long service life and reduced maintenance costs in demanding industrial environments.
