**Mechanical Seal IN0120.1120DUBVPGG**

The IN0120.1120DUBVPGG is a high-performance mechanical seal designed for reliable shaft sealing in a wide range of rotary equipment, including pumps, mixers, and compressors. This model belongs to the standardized IN120DU series, a comprehensive **каталог торцевих ущільнень** offering versatile sealing solutions. It is a direct functional equivalent to several prominent industry standards, specifically M211 R7.012, Vulcan 7D, Aesseal T01/T03D, Anga A3, and roten U2, ensuring broad compatibility and ease of replacement across diverse machinery fleets.

Constructed for durability and effective operation, the seal features a robust material configuration. The primary sealing face is provided by a ceramic moving part, known for its excellent wear resistance and hardness. This is paired with a graphite fixed part, which offers superior self-lubricating properties and thermal conductivity, promoting stable face performance and heat dissipation. The metal components are manufactured from corrosion-resistant AISI304 stainless steel, while the elastomer bellows or secondary seals are made from NBR (Nitrile Butadiene Rubber), suitable for applications involving oils, water, and many common fluids.

Precise engineering defines the critical **розміри торцевого ущільнення**, which are essential for correct installation and function. The seal is designed for a shaft diameter (d1) of 12 mm. The external diameter of the fixed part (d7) measures 23 mm, and the outer diameter of the moving part (d3) is 21 mm. The overall seal length (L3) is 18 mm. This compact cylindrical spring design (type of seal) provides consistent face loading through a single-coil spring, ensuring effective sealing even in applications with minor shaft runout or misalignment. The seal is classified under grade 120D, indicating its specific design and performance parameters within the catalog.

Key benefits of the IN0120.1120DUBVPGG include its interchangeability with multiple OEM seals, reducing inventory complexity and procurement lead times. The selected material combination ensures reliable performance in general industrial service with water, coolants, light oils, and other non-aggressive media. Its standardized dimensions and construction make it a practical and cost-effective choice for maintenance and repair operations across various industries, from chemical processing and water treatment to general manufacturing. When selecting a seal, always verify the exact shaft diameter, housing bore, and operational conditions to ensure optimal compatibility and service life.
