The mechanical seal IN0220.8UQQVGG is a precision-engineered component designed for reliable shaft sealing in demanding industrial applications. This model belongs to the comprehensive CATALOG OF MECHANICAL SEALS / IN9U/IN8U series, representing a robust solution for pumps, mixers, and other rotary equipment. Its construction is defined by a specific combination of materials and dimensions, ensuring compatibility and long-term performance.

A key feature of this seal is its design **с прижимным кольцом** (with a clamping ring), which facilitates secure installation and stable operation on the shaft. The seal is engineered for a nominal shaft diameter (d1) of 22.23 mm. Critical **розміри торцевого ущільнення** (mechanical seal dimensions) include an external diameter of the fixed part (d7) at 38.1 mm and an outer diameter of the moving part (d3) of 37.2 mm. The overall seal length (L3) is precisely 23.8 mm. These standardized dimensions allow for straightforward selection and replacement from any detailed **каталог торцевих ущільнень** (catalog of mechanical seals).

The IN0220.8UQQVGG utilizes high-performance materials to withstand rigorous operating conditions. Both the fixed and moving sealing faces are manufactured from **карбид кремния** (silicon carbide), a material renowned for its exceptional hardness, wear resistance, and corrosion stability. This pairing ensures a durable, low-leakage seal interface. The structural metal components are made from AISI 304 stainless steel, providing excellent resistance to corrosion and mechanical strength. The secondary sealing element is an NBR (Nitrile Butadiene Rubber) elastomer, offering reliable flexibility and resistance to oils and water within its temperature range. The designation "8U" in the model number indicates a specific **seal grade** within the series, correlating to its pressure and velocity capabilities.

This mechanical seal is suitable for applications in chemical processing, general industrial pumping, and water treatment where effective sealing of fluids is required. The combination of silicon carbide faces and stainless steel construction makes it a dependable choice for mediums that are abrasive, corrosive, or involve clean liquids. When selecting a seal, referencing the precise model IN0220.8UQQVGG and verifying all provided dimensions against your equipment specifications is essential for optimal performance and service life.
