The mechanical seal IN0280.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 ensures effective containment of fluids, preventing leakage and protecting equipment integrity.

Manufactured by Торцевое уплотнение, this seal is characterized by its robust material composition and precise **розміри торцевого ущільнення**. 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, which guarantees long service life and stable performance under harsh conditions. The metal structural components are fabricated from AISI304 stainless steel, offering excellent mechanical strength and corrosion resistance. The secondary elastomeric seal is made from NBR (Nitrile Butadiene Rubber), suitable for a wide range of oils, water, and fluids within its temperature compatibility range.

Key dimensional parameters are critical for correct installation and interchangeability. The seal is designed for a shaft diameter (d1) of 28 mm. The external diameter of the fixed part (d7) is 48 mm, while the outer diameter of the moving part (d3) measures 45 mm. The overall seal length (L3) is 50 mm. These precise **розміри торцевого ущільнення** must be verified against the equipment specifications to ensure a proper fit. The IN0280.JB103QQGG is classified as a seal **с прижимным кольцом** (with a gland ring), which facilitates secure mounting and alignment within the sealing chamber. Its design grade, JB103, indicates a specific configuration and balance suitable for various standard pump models.

This mechanical seal is ideal for applications in chemical processing, water treatment, irrigation systems, and general industrial pumping where reliability is paramount. When selecting a replacement or specifying a new seal, consulting the detailed **каталог торцевих ущільнень** for the INJB103 series is essential to confirm compatibility and technical suitability. The IN0280.JB103QQGG represents a dependable solution engineered to minimize downtime and maintenance costs through durable materials and precise manufacturing.
