The mechanical seal IN0320.4701.BVPGG is a robust double-tandem type seal designed for demanding industrial applications where reliable shaft sealing is critical. This model belongs to the comprehensive CATALOG OF MECHANICAL SEALS under the IN4701 series, representing a standardized solution for specific operational parameters. Its construction utilizes a material combination engineered for durability and chemical resistance, ensuring extended service life in challenging environments.

Key specifications define its precise application fit. The seal is configured for a shaft diameter (d1) of 32 mm. The external diameter of the fixed part (d7) measures 48 mm, while the outer diameter of the moving part (d3) is 47 mm, with an overall seal length (L3) of 61 mm. These precise **розміри торцевого ущільнення** are critical for correct installation and optimal performance within the designated housing. The material selection is strategic: the fixed part is manufactured from ceramic, offering exceptional hardness and wear resistance. The moving part consists of graphite, providing reliable self-lubricating properties and thermal conductivity. The metal components are made from AISI304 stainless steel, ensuring corrosion resistance, and the elastomeric elements are formed from NBR (Nitrile Butadiene Rubber), suitable for a wide range of fluids including oils, water, and some chemicals.

The double-tandem design of the IN0320.4701.BVPGG provides an enhanced sealing safety factor. This configuration incorporates two sets of sealing faces arranged in series, creating a primary and a secondary sealing barrier. This is particularly advantageous for applications involving volatile, hazardous, or abrasive media, as it significantly reduces the risk of leakage to the atmosphere. The seal effectively contains pressure from the equipment housing, protecting both the machinery and the operational environment.

For engineers and maintenance specialists selecting components from a **каталог торцевих ущільнень**, this model offers a clearly defined, application-ready solution. Its standardized design under the 4701 seal grade facilitates identification and replacement. The mechanical seal IN0320.4701.BVPGG is suitable for various rotating equipment such as pumps, mixers, and compressors where its tandem design adds a critical layer of operational security and environmental protection. Its specified dimensions and material composition make it a dependable choice for ensuring long-term sealing integrity in industrial fluid handling systems.
