The mechanical seal IN0280.4701.BVPGG is a robust dual-tandem configuration seal designed for demanding industrial applications where enhanced sealing security and leakage prevention are paramount. This model belongs to the comprehensive CATALOG OF MECHANICAL SEALS under the IN4701 series, representing a standardized solution for a wide range of rotary equipment. Its tandem design incorporates two sets of sealing faces arranged in series, providing a critical secondary containment barrier. This makes it particularly suitable for handling volatile, hazardous, or expensive media, as the primary seal leakage is directed to a controlled drain point rather than the environment.

Precise engineering defines the dimensional and material characteristics of this seal. It is configured for a shaft diameter (d1) of 28 mm, with an external diameter of the fixed part (d7) measuring 43 mm and an outer diameter of the moving part (d3) of 42 mm. The overall seal length (L3) is 51 mm. These specific **розміри торцевого ущільнення** are critical for ensuring a correct fit and optimal performance within the designated pump or mixer housing. The material selection ensures durability and chemical compatibility: the fixed sealing face is manufactured from high-wear ceramic, the moving face from resilient graphite, the metal structural components from corrosion-resistant AISI304 stainless steel, and the elastomeric elements from NBR (Nitrile Butadiene Rubber), which offers good resistance to oils and fuels.

As a key entry in any professional **каталог торцевих ущільнень**, the IN0280.4701.BVPGG provides a reliable, off-the-shelf sealing solution. Its construction guarantees stable operation under varying pressure conditions, with the tandem arrangement significantly extending service life and operational safety. The seal grade 4701 denotes its standardized design footprint, facilitating straightforward identification and replacement. This mechanical seal is engineered for use in centrifugal pumps, agitators, and compressors across chemical processing, petrochemical, and general industrial sectors, delivering dependable performance where single seals present an unacceptable risk.
