The mechanical seal IN0250.102UQQVGG is a precision-engineered component designed for reliable shaft sealing in demanding industrial pump applications. This model belongs to the standardized IN102U series, a comprehensive line featured in any professional **каталог торцевих ущільнень** (catalog of mechanical seals). Its construction is defined by robust materials and exact **розміри торцевого ущільнення** (mechanical seal dimensions), ensuring a perfect fit and long-term operational stability.

This seal is configured as a type with a clamping ring (с прижимным кольцом), which facilitates secure installation and maintains correct alignment on the shaft. The critical sealing faces utilize silicon carbide (карбид кремния) for both the fixed and moving parts. This material pairing offers exceptional resistance to abrasion, corrosion, and thermal shock, significantly extending service life compared to conventional materials. The metal structural components are manufactured from AISI304 stainless steel, providing excellent corrosion resistance and mechanical strength. The secondary sealing element is made from NBR (Nitrile Butadiene Rubber), a versatile elastomer suitable for a wide range of fluids, including oils, water, and many chemicals.

The precise dimensional parameters are key to its application. The seal is designed for a shaft diameter (d1) of 25 mm. Both the external diameter of the fixed part (d7) and the outer diameter of the moving part (d3) are 40 mm, contributing to a compact and balanced design. The overall seal length (L3) is 26 mm. These specific **розміри торцевого ущільнення** are critical for interchangeability and correct selection from the **каталог торцевих ущільнень**, guaranteeing compatibility with existing pump housings and gland plates.

The IN0250.102UQQVGG mechanical seal is engineered for use in centrifugal pumps, mixers, and other rotary equipment across chemical processing, water treatment, and general industrial sectors. Its primary benefits include reduced leakage, minimal maintenance requirements, and the ability to handle challenging operating conditions due to its silicon carbide faces and corrosion-resistant construction. When selecting a replacement or specifying a new seal, referencing the complete **каталог торцевих ущільнень** for the IN102U series is essential to verify all technical data and ensure optimal performance for your specific operational parameters.
