Mechanical seal IN0180.1120DUBVPGG, equivalent to M211 R7.018, equivalent to Vulcan 7D, equivalent to Aesseal T01,T03D, equivalent to Anga A3, equivalent to roten U2

**Mechanical Seal IN0180.1120DUBVPGG: A Universal Cartridge Seal for Demanding Applications**

The IN0180.1120DUBVPGG is a high-performance, standardized cartridge mechanical seal designed for reliable operation in a wide range of industrial rotary equipment. This model represents a direct and fully interchangeable equivalent to several prominent industry standards, including M211 R7.018, Vulcan 7D, Aesseal T01/T03D, Anga A3, and roten U2. Its universal design ensures easy integration and replacement, simplifying maintenance and procurement processes. This seal is cataloged within the comprehensive **каталог торцевих ущільнень** series IN120DU, offering a proven solution for sealing rotating shafts against fluid leakage.

**Precision Engineering and Robust Construction**

This seal is engineered with a balanced selection of materials to ensure durability and effective sealing across various media. The primary sealing faces consist of a stationary part made from graphite and a rotating part manufactured from high-grade ceramic, providing excellent wear resistance and low friction. The metal components are constructed from corrosion-resistant AISI304 stainless steel, while the elastomeric elements utilize NBR (Nitrile rubber), suitable for a broad spectrum of oils, water, and many industrial fluids. The actuation is provided by a reliable cylindrical spring, ensuring consistent face loading and stable performance under variable conditions.

**Key Technical Specifications and Dimensional Data**

Accurate **розміри торцевого ущільнення** are critical for proper installation and function. The IN0180.1120DUBVPGG is designed for a nominal shaft diameter (d1) of 18 mm. The external diameter of the fixed part (d7) measures 33 mm, and the outer diameter of the moving part (d3) is 29 mm. The overall seal length (L3) is 24 mm. These precise dimensions guarantee a correct fit within the seal chamber and secure positioning on the shaft, which is essential for achieving the intended seal life and preventing premature failure.

**Application and Benefits**

As part of the versatile IN120DU seal grade, this cartridge unit is suitable for pumps, mixers, and agitators in industries such as chemical processing, general manufacturing, water treatment, and HVAC. The pre-assembled cartridge design eliminates complex internal measurements and adjustments, significantly reducing installation time and potential for error. The combination of materials offers a robust sealing solution for applications involving water, light chemicals, coolants, and non-aggressive process fluids. Its wide equivalence makes it an optimal choice for standardizing seal inventories, reducing downtime, and ensuring operational continuity by providing a readily available alternative to multiple OEM part numbers.
