The IN0200.71UQQVGG is a robust mechanical face seal engineered for reliable shaft sealing in demanding industrial applications. This model belongs to the standardized IN71U/IN74U series, a comprehensive range featured in professional catalogs of mechanical seals. Its design incorporates a clamping ring (прижимное кольцо), which ensures secure and stable installation, critical for maintaining seal integrity under variable operational conditions.

Constructed for a nominal shaft diameter (d1) of 20 mm, the seal features a compact overall length (L3) of 26 mm. Both the rotating and stationary faces have an external diameter of 35 mm (d3 and d7), providing a balanced footprint for effective pressure distribution. The primary sealing faces are manufactured from silicon carbide (карбид кремния), a material renowned for its exceptional hardness, superior wear resistance, and excellent chemical inertness. This material pairing ensures long service life, minimal leakage, and reliable performance in abrasive or corrosive media. The structural metal components are made from AISI 304 stainless steel, offering good corrosion resistance and mechanical strength. The secondary elastomeric seal is made from NBR (Nitrile Butadiene Rubber), a versatile material suitable for a wide range of oils, fuels, and water within its temperature limits.

The precise dimensions of this mechanical seal, including the shaft diameter, outer diameters, and length, are critical parameters for proper selection and interchangeability. When consulting a catalog of mechanical seals, verifying these exact dimensions of the mechanical seal is essential for a successful replacement or new installation. The IN0200.71UQQVGG is designed for use in various rotary equipment such as pumps, mixers, and compressors, where it effectively prevents fluid leakage along the shaft. Its balanced design and high-quality material composition make it a dependable choice for ensuring operational efficiency, reducing maintenance downtime, and protecting equipment and the environment from potential leaks.
