Mechanical seal IN0280.9BQQVGG

The mechanical seal IN0280.9BQQVGG is a precision-engineered component designed for reliable shaft sealing in demanding industrial applications. This model belongs to the comprehensive CATALOG OF MECHANICAL SEALS / IN9B/IN8B series, representing a robust design featuring a clamping ring (type of seal: с прижимным кольцом). Its construction ensures optimal performance in pumps and mixers handling various fluids, where leak-tight integrity is critical.

Key technical specifications define the seal's compatibility and durability. The seal is engineered for a nominal shaft diameter d1 of 28.6 mm. The precise **розміри торцевого ущільнення** are crucial for correct installation: the external diameter of the fixed part (d7) is 50.8 mm, while the outer diameter of the moving part (d3) measures 51.5 mm. The overall seal length L3 is 37 mm. These dimensions ensure a proper fit within standard gland spaces. The seal's grade is designated as 9B, indicating its specific configuration within the catalog.

Material selection is paramount for longevity and chemical resistance. Both the fixed part and the moving part are manufactured from silicon carbide (карбид кремния), providing exceptional hardness, wear resistance, and compatibility with abrasive media. The metal components are constructed from AISI304 stainless steel, offering good corrosion resistance. The dynamic elastomer is made from NBR (Nitrile Butadiene Rubber), a material chosen for its reliable performance with oils, water, and many industrial fluids within its temperature range.

The inclusion of a clamping ring enhances the security of the seal assembly, preventing rotation and ensuring stable positioning during operation. This design is particularly beneficial in applications with vibration or variable rotational speeds. When consulting the **каталог торцевих ущільнень** for a replacement or a new design, the IN0280.9BQQVGG model stands out for its balanced combination of robust materials and precise engineering. Its specifications make it suitable for a wide range of standard industrial pumping equipment, contributing to reduced maintenance downtime and improved system reliability by providing a consistent and effective sealing solution.
