The mechanical seal IN0280.1120ABVPGG is a precision-engineered component designed for reliable shaft sealing in a wide range of industrial rotary equipment, including pumps, mixers, and compressors. As part of the standardized IN120A series featured in comprehensive mechanical seal catalogs, this model offers a proven balance of durability, chemical resistance, and consistent performance. Its construction adheres to precise dimensional specifications, ensuring compatibility and ease of installation in designated applications.

This seal features a cylindrical spring design, which provides uniform axial loading and stable face closure, critical for maintaining an effective seal under variable operational conditions. The fixed sealing ring is manufactured from graphite, a material chosen for its excellent self-lubricating properties and thermal conductivity, which promotes stable face operation and reduces wear. The complementary rotating face is crafted from high-grade ceramic, offering exceptional hardness and superior resistance to abrasion and corrosion, thereby ensuring long-term sealing integrity. The metallic components are constructed from AISI304 stainless steel, providing robust structural support and corrosion resistance in many common industrial environments. The secondary sealing element utilizes NBR (Nitrile Butadiene Rubber), a versatile elastomer known for its good resistance to oils, fuels, and a range of fluids.

Key mechanical dimensions of the IN0280.1120ABVPGG are critical for proper selection and interchangeability. The seal is designed for a nominal shaft diameter (d1) of 28 mm. The outer diameter of the moving part (d3) measures 40 mm, while the external diameter of the fixed part (d7) is 43.3 mm. The overall seal length (L3) is 29 mm. These precise **розміри торцевого ущільнення** are essential data points when consulting a **каталог торцевих ущільнень** to identify a correct replacement or a new application-specific seal, guaranteeing proper fit within the seal chamber and on the shaft.

The IN0280.1120ABVPGG mechanical seal is engineered for applications requiring a dependable seal in pumps handling water, coolants, light oils, and various non-aggressive chemical fluids within the compatibility range of its constituent materials. Its design prioritizes operational reliability, reduced maintenance downtime, and prevention of fluid leakage, contributing to enhanced equipment efficiency and safety. When selecting a mechanical seal, referencing the complete technical data and application guidelines for the IN120A series is strongly recommended to confirm suitability for specific pressure, temperature, and media conditions.
