The mechanical seal IN0310.9UQQVGG is a precision-engineered component designed for reliable shaft sealing in demanding industrial applications. This model belongs to the specialized IN9U/IN8U series within the comprehensive catalog of mechanical seals, representing a robust solution for pump and rotating equipment maintenance. Its construction is defined by a balanced selection of materials and precise dimensions, ensuring compatibility and long-term performance.

A key feature of this seal is its design with a clamping ring (type of seal: с прижимным кольцом), which facilitates secure installation and stable operation under variable pressure conditions. 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 harsh media. The metal components are fabricated from AISI304 stainless steel, providing structural integrity and corrosion resistance. The secondary elastomeric seal is made from NBR (Nitrile rubber), a material chosen for its reliable performance with oils, water, and many industrial fluids within a standard temperature range.

Critical dimensions of the mechanical seal are paramount for correct selection. The IN0310.9UQQVGG is engineered for a nominal shaft diameter (d1) of 31.75 mm. The external diameter of the fixed part (d7) is 47.63 mm, while the outer diameter of the moving part (d3) measures 48.3 mm. The overall seal length (L3) is 27 mm. These precise dimensions of the mechanical seal must be verified against the equipment's housing and shaft specifications to guarantee a proper fit. The seal is classified under grade 9U, indicating its specific configuration and performance characteristics within the product line.

When consulting the catalog of mechanical seals, the IN0310.9UQQVGG stands out for applications requiring a durable, cartridge-style seal with a clamping mechanism. Its design is suitable for various centrifugal pumps, mixers, and compressors across chemical processing, water treatment, and general industrial sectors. The combination of silicon carbide faces and stainless steel construction makes it a versatile choice for challenging environments where leakage prevention and operational reliability are critical. Proper installation in accordance with the specified dimensions ensures optimal sealing efficiency and contributes to reduced downtime and maintenance costs.
