Mechanical seal IN0280.960QQVGG

The mechanical seal IN0280.960QQVGG is a precision-engineered component designed for reliable shaft sealing in demanding industrial pump applications. This model belongs to the IN960 series, a comprehensive range featured in our catalog of mechanical seals, known for robust construction and consistent performance. Manufactured to exacting standards, this seal incorporates a press ring (прижимное кольцо) design, ensuring secure installation and optimal alignment on the shaft.

Constructed for durability, the primary 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 in challenging media. The metal components are fabricated from AISI304 stainless steel, providing excellent structural integrity and corrosion resistance. The secondary elastomer seal is made from NBR (Nitrile Butadiene Rubber), a material chosen for its reliable performance with oils, water, and many industrial fluids within its temperature range.

Critical dimensions of this mechanical seal are precisely defined to ensure compatibility and correct function. The shaft diameter (d1) is 28 mm. The external diameter of the fixed part (d7) measures 50 mm, while the outer diameter of the moving part (d3) is 42 mm. The overall seal length (L3) is 35 mm. These specific dimensions of the mechanical seal are crucial for proper selection and are clearly detailed in technical documentation to facilitate accurate replacement from the catalog. The seal is classified under grade 960, indicating its specific design configuration and performance characteristics within the series.

The IN0280.960QQVGG mechanical seal is suitable for a wide array of rotary equipment, including centrifugal pumps, mixers, and compressors, where it effectively prevents leakage along the rotating shaft. Its design prioritizes long-term sealing reliability, reduced maintenance downtime, and operational efficiency. When consulting the catalog of mechanical seals for a replacement or upgrade, the precise model number and dimensional parameters are essential for identifying the correct component. This seal represents a balanced solution, combining high-wear materials with a practical design for industrial fluid handling systems.
