**Mechanical Seal IN0220.1120DUBVPGG: A Universal Cartridge Seal for Demanding Applications**

The IN0220.1120DUBVPGG is a high-performance, cartridge-type mechanical seal designed for reliable operation in pumps, mixers, and other rotary equipment. This model represents a direct and fully interchangeable equivalent to several prominent industry standards, including M211 R7.022, Vulcan 7D, Aesseal T01/T03D, Anga A3, and Roten U2. Its universal compatibility makes it an essential component for maintenance and repair operations, ensuring seamless replacement without equipment modification.

Constructed for durability and chemical resistance, the seal features a robust material configuration. The primary sealing face is manufactured from high-grade ceramic, providing excellent wear resistance and a smooth running surface. The stationary seat is made of graphite, ensuring stable performance and effective heat dissipation. The metal components are fabricated from AISI304 stainless steel, offering superior corrosion resistance, while the elastomeric bellows is made of NBR (Nitrile rubber), suitable for a wide range of fluids including oils, water, and many chemicals. The drive mechanism utilizes a cylindrical spring design, ensuring consistent face loading and reliable operation under variable conditions.

Precise **розміри торцевого ущільнення** are critical for correct installation and performance. This seal is engineered for a shaft diameter (d1) of 22 mm. The outer diameter of the moving part (d3) is 33 mm, and the outer diameter of the fixed part (d7) measures 37 mm. The overall seal length (L3) is 25 mm. These dimensions guarantee a precise fit and optimal sealing function within the designated housing.

As part of the comprehensive **каталог торцевих ущільнень**, specifically the IN120DU series, this model is classified under seal grade 120D. Its cartridge design simplifies installation and alignment, significantly reducing the risk of assembly errors and ensuring quick, trouble-free maintenance. The primary applications include centrifugal pumps, agitators, and compressors handling water, coolants, light chemicals, and other non-aggressive media in industrial, chemical, and municipal settings.

The Mechanical Seal IN0220.1120DUBVPGG delivers a dependable sealing solution, combining proven material science with precise engineering. Its extensive cross-referencing and standardized dimensions make it a versatile and cost-effective choice for operational reliability and inventory simplification.
