Mechanical seal IN0200.JB103QQGG

The mechanical seal IN0200.JB103QQGG is a precision-engineered component designed for reliable shaft sealing in demanding industrial pump applications. This model belongs to the standardized INJB103 series, a comprehensive range featured in any professional **каталог торцевих ущільнень**. Its construction is defined by robust materials and exact **розміри торцевого ущільнення**, ensuring compatibility and long-term performance in systems with a 20 mm shaft diameter (d1).

This seal is classified as a **type of seal: с прижимным кольцом** (with a gland ring), which facilitates secure installation and stable operation. The primary sealing faces utilize silicon carbide (карбид кремния) for both the fixed and moving parts, providing exceptional resistance to abrasion, corrosion, and thermal shock. This material pairing ensures minimal wear and consistent leak-free performance. The metal structural components are manufactured from AISI304 stainless steel, offering good general corrosion resistance and mechanical strength. The secondary elastomer seal is made from NBR (Nitrile Butadiene Rubber), suitable for a wide range of fluids including oils, water, and many chemicals within its temperature range.

Critical **розміри торцевого ущільнення** for installation and housing design include an external diameter of the fixed part (d7) of 40 mm and an outer diameter of the moving part (d3) of 37 mm. The overall seal length (L3) is 44 mm. These precise dimensions are essential for correct selection from the **каталог торцевих ущільнень** and for ensuring a proper fit within the equipment seal chamber.

The IN0200.JB103QQGG mechanical seal is engineered for applications where durability and reliability are paramount. Its balanced design and high-grade material composition make it suitable for centrifugal pumps, mixers, and other rotating equipment in chemical processing, water treatment, and general industrial services. When selecting a seal from the **каталог торцевих ущільнень**, this model represents a solution that combines proven JB103 seal geometry with premium materials for extended service life and reduced maintenance intervals.
