**Mechanical Seal IN0280.8UQQVGG: Technical Description**

The IN0280.8UQQVGG is a precision-engineered mechanical face seal designed for reliable shaft sealing in demanding industrial applications. This model belongs to the comprehensive **catalog of mechanical seals** IN9U/IN8U series, known for their robust construction and standardized dimensions. It is engineered to prevent leakage of fluids in pumps, mixers, and other rotary equipment, ensuring operational integrity and environmental safety.

**Construction and Material Specifications**
This seal features a balanced design with a clamping ring (type: с прижимным кольцом), which facilitates secure installation and stable operation. The primary sealing faces are manufactured from silicon carbide (карбид кремния) for both the fixed and moving parts. This material selection provides exceptional resistance to abrasion, corrosion, and thermal shock, ensuring long service life even in harsh media. The metallic components are constructed from AISI304 stainless steel, offering good general corrosion resistance and structural strength. The secondary elastomeric seal is made from NBR (Nitrile Butadiene Rubber), a material chosen for its compatibility with a wide range of oils, water, and certain chemicals, providing reliable static sealing.

**Critical Dimensional Data**
Precise **dimensions of the mechanical seal** are paramount for correct installation and performance. The IN0280.8UQQVGG is designed for a nominal shaft diameter (d1) of 28.58 mm. The external diameter of the fixed part (d7) is 44.45 mm, while the outer diameter of the moving part (d3) measures 43.5 mm. The overall seal length (L3) is 27 mm. These standardized dimensions allow for straightforward selection and replacement from the relevant **catalog of mechanical seals**, ensuring interchangeability and simplifying maintenance procedures.

**Performance and Application**
Classified under seal grade 8U, this model is suitable for a broad spectrum of general industrial duties. Its construction is ideal for applications involving water, light corrosive fluids, and various process liquids where reliable sealing is required. The combination of silicon carbide faces ensures low friction and minimal wear, contributing to energy efficiency and reduced maintenance downtime. When consulting the **catalog of mechanical seals** for a replacement or upgrade, the IN0280.8UQQVGG represents a robust solution where precise **dimensions of the mechanical seal** and material compatibility are critical success factors.
