Mechanical seal IN0250.1120DUBVPGG, equivalent to M211 R7.025, equivalent to Vulcan 7D, equivalent to Aesseal T01,T03D, equivalent to Anga A3, equivalent to roten U2

The mechanical seal IN0250.1120DUBVPGG is a robust and versatile cartridge-type seal designed for reliable shaft sealing in a wide range of industrial rotary equipment. This model belongs to the standardized IN120DU series, a comprehensive **каталог торцевих ущільнень** offering proven solutions for pump and mixer applications. It serves as a direct functional equivalent to several well-known industry standards, including M211 R7.025, Vulcan 7D, Aesseal T01/T03D, Anga A3, and Roten U2, ensuring broad compatibility and ease of replacement.

Engineered for a nominal shaft diameter (d1) of 25 mm, the seal features precise **розміри торцевого ущільнення** critical for correct installation and performance. The key dimensions include an outer diameter of the moving part (d3) at 36 mm and an outer diameter of the fixed part (d7) at 40 mm, with a total seal length (L3) of 27 mm. The construction utilizes a carefully selected material combination for durability and chemical resistance. The primary sealing faces consist of a graphite stationary part and a ceramic rotating part, providing excellent wear characteristics and thermal conductivity. The metal components are manufactured from corrosion-resistant AISI304 stainless steel, while the elastomer bellows is made of NBR (Nitrile Butadiene Rubber), suitable for a variety of fluids including oils, water, and many chemicals. The actuation is provided by a cylindrical spring design, ensuring consistent face loading and stable operation.

This configuration makes the IN0250.1120DUBVPGG ideal for applications in chemical processing, general industrial water systems, irrigation, and light-duty fluid transfer where reliable sealing of shafts against leakage is paramount. Its cartridge design simplifies installation and maintenance, reducing the risk of assembly errors. The specified material grades and construction ensure long service life and consistent performance under standard operating conditions, providing an effective sealing solution for OEMs and maintenance operations seeking a cross-compatible, high-quality mechanical seal.
