Mechanical seal IN0180.4701.BVPGG

The mechanical seal IN0180.4701.BVPGG is a robust double-tandem type seal designed for demanding industrial applications where reliable shaft sealing is critical. This model belongs to the standardized IN4701 seal grade, a series widely recognized for its balanced design and compatibility across various pump and rotating equipment models. Its construction ensures enhanced operational safety by providing two sequential sealing faces, creating an effective barrier against leakage, especially in challenging environments involving volatile or hazardous media.

Manufactured to precise specifications, the seal features a fixed part crafted from high-grade ceramic, offering exceptional hardness and wear resistance for long-term sealing face integrity. The complementary moving part is manufactured from graphite, a material selected for its self-lubricating properties and excellent compatibility with a wide range of fluids. The metal components are constructed from AISI304 stainless steel, providing reliable corrosion resistance and structural strength. The secondary sealing elements utilize NBR (Nitrile Butadiene Rubber), a versatile elastomer known for its good resistance to oils, fuels, and a broad temperature range.

Key dimensional parameters define the seal's installation fit and functional envelope. The mechanical seal IN0180.4701.BVPGG is engineered for a nominal shaft diameter (d1) of 18 mm. The external diameter of its fixed part (d7) measures 35 mm, while the outer diameter of the moving part (d3) is 30.5 mm. The overall seal length (L3) is 36 mm. These precise **розміри торцевого ущільнення** are critical for correct selection and installation, ensuring optimal performance and preventing premature failure. Accurate reference to these dimensions in any **каталог торцевих ущільнень** is essential for maintenance engineers and procurement specialists.

This double-tandem configuration is particularly suited for applications in chemical processing, petrochemical industries, and fluid transfer systems where an additional safety stage is required. The design helps contain potential primary seal failure, directing leakage to a safe discharge point. When selecting a replacement or specifying a new seal, the IN0180.4701.BVPGG model provides a dependable solution characterized by its material durability, precise engineering, and the operational security inherent in its tandem design. Its standardized profile facilitates straightforward cross-referencing and sourcing from comprehensive industrial seal catalogs.
