Mechanical seal IN0280.120HBVPGG

The mechanical seal IN0280.120HBVPGG is a robust and precisely engineered component designed for reliable shaft sealing in demanding industrial pump applications. This model belongs to the standardized IN120HB series, a comprehensive line featured in professional catalogs of mechanical seals, known for its consistent quality and dimensional interchangeability. Its construction utilizes a cylindrical spring design, which provides uniform axial load and stable sealing face contact during operation, ensuring consistent performance across varying pressures and shaft runouts.

Critical dimensions of this mechanical seal, including the shaft diameter (d1) of 28 mm, are fundamental for correct selection and installation. The external diameter of the fixed part (d7) is 43 mm, while the moving part features an outer diameter (d3) of 47 mm. The overall seal length (L3) is 35.5 mm. These precise **розміри торцевого ущільнення** are essential for engineers and maintenance technicians when integrating the seal into existing equipment or specifying it for new assemblies, ensuring a perfect fit within the gland space.

Material selection for the IN0280.120HBVPGG is optimized for durability and chemical resistance. The primary sealing face of the fixed part is manufactured from high-grade ceramic, offering exceptional hardness and wear resistance against abrasive media. The corresponding moving ring is crafted from premium graphite, providing excellent self-lubricating properties and a reliable mating surface. The metal components are constructed from AISI304 stainless steel, delivering strong corrosion resistance. The secondary elastomeric seal is made from NBR (Nitrile rubber), suitable for a wide range of oils, water, and fluids within its temperature range.

As a key entry in any **каталог торцевих ущільнень**, the IN0280.120HBVPGG seal is engineered for applications involving water, light oils, coolants, and various non-aggressive process fluids. Its 120HB seal grade indicates a specific configuration balanced for general industrial service. The combination of a ceramic-graphite face pairing and a cylindrical spring mechanism results in a seal that maintains integrity under dynamic conditions, minimizes leakage, and extends service intervals, thereby reducing maintenance costs and downtime for rotating equipment.
