Mechanical seal IN0280.102UQQVGG

The mechanical seal IN0280.102UQQVGG is a precision-engineered component from the IN102U series, designed for reliable shaft sealing in demanding industrial pump applications. This model represents a standardized solution within the comprehensive **каталог торцевих ущільнень**, offering predictable performance and interchangeability. Its construction is defined by a balanced selection of materials and precise **розміри торцевого ущільнення**, ensuring optimal compatibility and long-term operational stability.

This seal is configured as a type "с прижимным кольцом" (with a clamping ring), which facilitates secure installation and maintains correct alignment of the sealing faces. The core sealing interface is formed by two rings manufactured from silicon carbide (карбид кремния), a material renowned for its exceptional hardness, wear resistance, and chemical inertness. The use of identical silicon carbide for both the fixed and moving parts provides excellent dry-running tolerance and superior performance in abrasive or corrosive media. The structural metal components are constructed from AISI304 stainless steel, offering good general corrosion resistance and mechanical strength.

Critical dimensional parameters are meticulously defined to ensure proper fit and function. The seal is engineered for a shaft diameter (d1) of 28 mm. Both the external diameter of the fixed part (d7) and the outer diameter of the moving part (d3) are standardized at 43 mm, contributing to its versatility in housing designs. The overall seal length (L3) is 26 mm, a key dimension for axial space planning during pump assembly or maintenance. The secondary elastomeric sealing element is made from NBR (Nitrile Butadiene Rubber), a material chosen for its robust resistance to oils, fuels, and a wide range of industrial fluids, ensuring a reliable static seal.

As part of the structured **каталог торцевих ущільнень**, the IN0280.102UQQVGG mechanical seal is ideal for use in centrifugal pumps, mixers, and other rotating equipment across chemical processing, water treatment, and general industrial sectors. Its standardized **розміри торцевого ущільнення** allow for straightforward selection and replacement, minimizing downtime. The combination of silicon carbide faces and a durable NBR elastomer delivers a robust sealing solution capable of handling challenging conditions, including those with moderate abrasives or temperature fluctuations, thereby enhancing equipment reliability and reducing maintenance frequency.
