The mechanical seal IN0200.74UQQVGG is a precision-engineered component designed for reliable shaft sealing in demanding industrial pump applications. This model belongs to the comprehensive CATALOG OF MECHANICAL SEALS / IN71U/IN74U series, representing a robust solution for equipment requiring durable and efficient fluid containment. Its construction is defined by a balanced selection of high-performance materials and precise dimensions, ensuring compatibility and long service life.

Key to the seal's performance is its material composition. Both the fixed and moving seal faces are manufactured from silicon carbide (карбид кремния), a material renowned for its exceptional hardness, wear resistance, and chemical inertness. This pairing provides superior sealing characteristics and extended operational longevity, even in abrasive or corrosive media. The metal structural components are made from AISI304 stainless steel, offering excellent corrosion resistance and mechanical strength. The secondary sealing element utilizes NBR (Nitrile Butadiene Rubber), a versatile elastomer known for its good resistance to oils, fuels, and a wide range of fluids.

The precise **розміри торцевого ущільнення** are critical for correct installation and function. The mechanical seal IN0200.74UQQVGG is designed for a shaft diameter (d1) of 20 mm. Both the external diameter of the fixed part (d7) and the outer diameter of the moving part (d3) measure 35 mm, contributing to a compact and balanced design. The overall seal length (L3) is 26 mm. This specific configuration, identified as seal grade 74U, features a design **с прижимным кольцом** (with a clamping ring), which facilitates secure mounting and stable operation on the shaft.

This mechanical seal is engineered for applications where dependable sealing is paramount, such as in centrifugal pumps, mixers, and compressors across chemical processing, water treatment, and general industrial sectors. When selecting a seal from the **каталог торцевих ущільнень**, the IN0200.74UQQVGG stands out for its combination of robust silicon carbide faces, corrosion-resistant metal parts, and standardized dimensions, providing a reliable and maintenance-reducing sealing solution. Its design ensures effective prevention of fluid leakage, protection of bearing assemblies, and support for overall equipment efficiency.
