The mechanical seal IN0280.125QQVGG is a precision-engineered component designed for reliable shaft sealing in rotating equipment. This model belongs to the IN125 series, a comprehensive line featured in any professional **каталог торцевих ущільнень**. It is engineered to prevent fluid leakage in pumps, mixers, and similar machinery, ensuring operational efficiency and environmental safety.

Constructed for durability and performance, the seal incorporates a stationary face and a rotating face both manufactured from silicon carbide (карбид кремния), a material renowned for its exceptional hardness, wear resistance, and chemical inertness. The metal components are made from AISI304 stainless steel, providing robust structural integrity and corrosion resistance. The secondary sealing element utilizes NBR (Nitrile Butadiene Rubber), offering reliable elasticity and compatibility with a wide range of fluids, including oils, water, and certain chemicals.

Critical **розміри торцевого ущільнення** are precisely defined for correct installation and function. The seal is designed for a shaft diameter (d1) of 28 mm. The external diameter of the fixed part (d7) is 43 mm, while the outer diameter of the moving part (d3) measures 42 mm. The overall seal length (L3) is 45 mm. These dimensions ensure a proper fit within the seal chamber and correct face loading. The design is classified as type "с прижимным кольцом" (with a gland ring), which facilitates secure mounting and alignment. The seal carries a pressure rating consistent with class 125 standards.

The IN0280.125QQVGG mechanical seal is suitable for applications in chemical processing, water treatment, general industrial pumps, and food processing equipment where its material combination and sealing class are applicable. Its design prioritizes long service life, minimal maintenance requirements, and reliable performance under standard operational conditions. When selecting a seal, referencing the precise specifications in the **каталог торцевих ущільнень** is essential to ensure compatibility with your equipment's operational parameters and fluid media.
