**Mechanical Seal IN0280.1120DBVPGG: A Universal Replacement Solution**

The IN0280.1120DBVPGG is a high-precision mechanical seal designed as a direct universal replacement for a wide range of popular industry models. This unit is fully equivalent to seals such as M211 R7.028, Vulcan 7D, Aesseal T01/T03D, Anga A3, and Roten U2, ensuring broad compatibility and simplified inventory management. As part of the comprehensive **каталог торцевих ущільнень (catalog of mechanical seals)** series IN120D, this model adheres to standardized dimensions and performance criteria for reliable interchangeability.

**Construction and Material Specifications**
Engineered for durability and effective sealing performance, the seal features a robust material composition. The primary sealing face is crafted from ceramic (moving part), paired with a graphite stationary face (fixed part), providing excellent wear resistance and stable friction characteristics. The metallic components are manufactured from corrosion-resistant AISI304 stainless steel. The secondary elastomeric seal utilizes NBR (Nitrile) rubber, offering solid compatibility with a variety of fluids including oils, water, and many industrial mediums. The actuation is provided by a cylindrical spring design, ensuring consistent face loading and reliable operation under variable conditions.

**Critical Dimensional Data and Application**
Precise **розміри торцевого ущільнення (dimensions of the mechanical seal)** are crucial for correct installation and function. This model is configured for a shaft diameter (d1) of 28 mm. The external diameter of the fixed part (d7) measures 43 mm, while the outer diameter of the moving part (d3) is 40 mm. The overall seal length (L3) is 29 mm. These standardized dimensions classify it under the seal grade 120D. The cylindrical spring type and compact design make it suitable for various rotary equipment, including pumps, mixers, and compressors, across chemical, water treatment, and general industrial sectors.

**Key Advantages and Usage**
The primary benefit of the IN0280.1120DBVPGG mechanical seal lies in its role as a consolidated replacement part, reducing the need to source multiple OEM-specific seals. Its material selection ensures performance in applications with moderate abrasive and corrosive properties. When selecting a seal from the **каталог торцевих ущільнень**, verifying these precise **розміри торцевого ущільнення** against your equipment's housing and shaft is essential for a leak-free installation. This model represents a cost-effective and readily available solution for maintenance and repair operations, designed to restore equipment to its original sealing integrity.
