The mechanical seal IN0250.802.QQVGG is a robust double-tandem type seal engineered for demanding applications requiring enhanced sealing security. This model belongs to the comprehensive IN802 series, a prominent line within the catalog of mechanical seals, known for its reliable performance in challenging operational environments. Its tandem configuration provides a critical secondary sealing barrier, significantly increasing system safety and containment, which is essential for handling aggressive, toxic, or valuable media.

Constructed for precision and durability, the seal features key components manufactured from high-performance materials. Both the fixed and moving seal faces are crafted from silicon carbide (карбид кремния), a material selected for its exceptional hardness, superior wear resistance, and excellent chemical inertness. The metal structural components are made from AISI304 stainless steel, ensuring good corrosion resistance and structural integrity. The secondary sealing element utilizes VITON elastomer, known for its broad chemical compatibility and reliable performance across a wide temperature range.

Critical dimensions of the mechanical seal are precisely defined to ensure correct installation and optimal function. The seal is designed for a shaft diameter (d1) of 25 mm. The external diameter of the fixed part (d7) measures 40 mm, while the outer diameter of the moving part (d3) is 43 mm. The overall seal length (L3) is 39 mm. These precise dimensions of the mechanical seal are crucial for proper integration into pump housings and gland plates, and they are clearly specified in technical documentation and relevant catalogs to facilitate accurate selection.

The IN0250.802.QQVGG is suitable for a variety of industrial applications, including chemical processing, petrochemical pumps, and other equipment where preventing leakage of hazardous fluids is paramount. Its tandem design offers a clear operational advantage by allowing for the monitoring of the primary seal's condition and providing a fail-safe secondary containment. When consulting the catalog of mechanical seals for a reliable, dimensionally specified solution for shafts of 25 mm, the IN0250.802.QQVGG represents a technically sound choice, balancing advanced material science with proven tandem sealing architecture for enhanced operational safety and equipment longevity.
