**Product Description: Mechanical Seal IN0280.1120DUBVPGG**

The IN0280.1120DUBVPGG is a high-performance mechanical face seal designed for reliable shaft sealing in a wide range of industrial rotary equipment. This model represents a standardized and widely compatible solution, engineered to ensure operational integrity in pumps, mixers, and agitators. Its design and material composition provide a robust sealing mechanism for applications involving water, oils, and various mild chemical fluids.

**Technical Specifications and Construction**
This seal is classified under the IN120DU series within the catalog of mechanical seals. Its precise dimensions are critical for correct installation and performance. The seal is configured for a shaft diameter (d1) of 28 mm, with an overall seal length (L3) of 29 mm. The external diameter of the stationary part (d7) is 43 mm, while the rotating part features an outer diameter (d3) of 40 mm. These specific dimensions of the mechanical seal must be verified against the equipment's gland and shaft specifications to ensure a proper fit.

The component materials are selected for durability and chemical compatibility. The primary sealing faces consist of a rotating ceramic ring and a stationary graphite ring, offering excellent wear resistance and stable friction characteristics. The metal components are manufactured from AISI304 stainless steel, providing good corrosion resistance. The secondary elastomeric sealing element is made from NBR (Nitrile Butadiene Rubber), suitable for a broad temperature range and compatible with many industrial fluids. The actuation force is provided by a cylindrical spring design, ensuring consistent face loading and reliable performance under variable operational conditions.

**Cross-Reference and Compatibility**
A key advantage of the IN0280.1120DUBVPGG mechanical seal is its direct equivalence to several major industry standards. It serves as a functional replacement for models including M211 R7.028, Vulcan 7D, Aesseal T01 and T03D, Anga A3, and roten U2. This extensive interchangeability makes it a versatile and readily available component for maintenance and repair operations, simplifying procurement from the catalog of mechanical seals.

**Application and Benefits**
This seal is suitable for general industrial service in standard duty pumps. The combination of ceramic, graphite, and NBR ensures a reliable seal in common applications, helping to prevent fluid leakage, reduce maintenance downtime, and protect equipment from damage. When selecting this seal, always confirm the exact dimensions of the mechanical seal and the chemical compatibility of its materials with the specific process fluid.
