The mechanical seal model IN0120.2100L.QQVGG is a precision-engineered bellows-type sealing solution designed for demanding rotary shaft applications. This unit belongs to the comprehensive **каталог торцевих ущільнень** series IN2100/IN2100L, representing a standardized yet highly reliable component for pump and mixer assemblies. Its construction is defined by a balanced selection of materials and precise **розміри торцевого ущільнення**, ensuring optimal performance and longevity in challenging operational environments.

This seal is configured for a nominal shaft diameter (d1) of 12 mm. The primary sealing faces consist of silicon carbide (карбид кремния) for both the fixed and moving parts, providing exceptional resistance to abrasion, corrosion, and thermal shock. This material pairing ensures stable frictional characteristics and minimal wear over extended service periods. The stationary part features an external diameter (d7) of 23 mm, while the rotating face has an outer diameter (d3) of 22 mm. The overall seal length (L3) is precisely 26.5 mm, a critical dimension for correct installation and housing fit. The secondary sealing element is a VITON (FKM) elastomer bellows, which offers excellent chemical resistance and flexibility across a wide temperature range. The metal structural components are fabricated from AISI 304 stainless steel, providing robust mechanical support and corrosion resistance.

The designation "2100L" indicates a specific seal grade within the catalog, characterized by its bellows (сильфонное) design. This configuration eliminates the need for a dynamic O-ring, reducing friction and hang-up tendencies, which is particularly advantageous in applications involving viscous media or where crystallizing fluids are present. The IN0120.2100L.QQVGG is engineered for reliability in chemical processing, petrochemical, and general industrial pumping systems where leak-free operation is critical. Its standardized dimensions facilitate straightforward selection from the **каталог торцевих ущільнень** and simplify inventory management for maintenance operations. When specifying a replacement, verifying the exact **розміри торцевого ущільнення**—including shaft diameter, housing bore, and overall length—is essential to ensure compatibility and optimal sealing performance.
