The mechanical seal IN0240.74UQQVGG 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, offering a standardized solution for maintenance and repair operations. Manufactured by Торцевое уплотнение, it represents a robust construction with a balanced selection of materials for enhanced durability and chemical resistance.

This seal is classified under the 74U seal grade, indicating its specific design configuration and performance characteristics. A key feature is its inclusion of a прижимное кольцо (clamping ring), which ensures secure and uniform axial positioning on the shaft, simplifying installation and improving operational stability. The seal's critical dimensions are precisely defined: it is engineered for a shaft diameter d1 of 24 mm, with both the external diameter of the fixed part d7 and the outer diameter of the moving part d3 measuring 39 mm. The overall seal length L3 is 28.5 mm. These consistent розміри торцевого ущільнення (mechanical seal dimensions) are essential for correct fitment and interchangeability, which is a fundamental advantage of consulting a detailed каталог торцевих ущільнень (catalog of mechanical seals).

Material selection is paramount for seal longevity. The IN0240.74UQQVGG utilizes карбид кремния (silicon carbide) for both the fixed and moving sealing faces. This material provides exceptional hardness, excellent wear resistance, and good thermal conductivity, making it suitable for handling abrasive media and extending service intervals. The metal structural components are fabricated from AISI304 stainless steel, offering reliable corrosion resistance in a wide range of environments. The secondary sealing element is made from NBR (Nitrile Butadiene Rubber), a versatile elastomer known for its good resistance to oils, fuels, and water, ensuring an effective static seal.

In practical application, this mechanical seal is ideal for centrifugal pumps, mixers, and other rotary equipment where sealing water, light oils, or certain process fluids is required. Its balanced design and quality material composition contribute to reduced leakage, lower maintenance costs, and increased equipment uptime. For engineers and procurement specialists, referencing the precise model IN0240.74UQQVGG within the relevant каталог торцевих ущільнень guarantees receipt of a component with these exact specifications, ensuring compatibility and performance in the intended application.
