Mechanical seal IN0300.1120DUBVPGG, equivalent to M211 R7.030, equivalent to Vulcan 7D, equivalent to Aesseal T01,T03D, equivalent to Anga A3, equivalent to roten U2

The mechanical seal IN0300.1120DUBVPGG is a robust and versatile cartridge-type sealing solution engineered for reliable performance in a wide range of rotary shaft applications. This model is a direct equivalent to several industry-standard seals, including M211 R7.030, Vulcan 7D, Aesseal T01/T03D, Anga A3, and roten U2, ensuring broad compatibility and ease of replacement. It is cataloged within the comprehensive **каталог торцевих ущільнень** under the category IN120DU, representing a standardized design for common industrial use.

Constructed for durability, the seal incorporates a high-performance material combination. The primary sealing face is comprised of a ceramic moving part, offering exceptional hardness and wear resistance. This interfaces with a fixed part made of graphite, providing excellent self-lubricating properties and thermal conductivity for stable operation. The metal components are fabricated from corrosion-resistant AISI304 stainless steel, while the elastomeric bellows is made of NBR (Nitrile rubber), suitable for a variety of fluids including oils, water, and many chemicals. The assembly is energized by a cylindrical spring, ensuring consistent face loading and reliable sealing under variable conditions.

Critical **розміри торцевого ущільнення** are precisely defined for correct installation and interchangeability. The seal is designed for a shaft diameter (d1) of 30 mm. The external diameter of the fixed part (d7) measures 45 mm, and the outer diameter of the moving part (d3) is 43 mm. The overall seal length (L3) is 30 mm. These dimensions are essential for verifying fit within the equipment's stuffing box or seal chamber.

As a cartridge unit, the IN0300.1120DUBVPGG simplifies installation and maintenance, reducing the risk of assembly errors. Its design is suitable for pumps, mixers, and other rotating equipment handling non-aggressive media in general industrial, chemical, and municipal water applications. The seal grade 120D indicates its standardized configuration within the product line. When selecting a mechanical seal, consulting the detailed **каталог торцевих ущільнень** with all specified dimensions ensures the correct model is chosen for optimal sealing performance and service life.
