Mechanical seal IN0300.120VPGG

The mechanical seal IN0300.120VPGG is a precision-engineered component designed for reliable shaft sealing in demanding industrial applications. This model belongs to the IN120 series within the comprehensive catalog of mechanical seals, offering a standardized solution for pumps and rotating equipment. Its construction ensures effective containment of fluids, prevention of leaks, and long-term operational stability under specified conditions.

This seal features a robust design with key dimensions critical for proper installation and function. The shaft diameter (d1) is 18 mm, while the external diameter of the fixed part (d7) measures 45 mm and the outer diameter of the moving part (d3) is 44 mm. The overall seal length (L3) is 31.5 mm. These precise dimensions of the mechanical seal must be carefully verified against the equipment specifications to guarantee correct fitment and optimal performance. The seal is classified under grade 120, indicating its performance characteristics and suitable application range.

Material selection is paramount for durability and chemical resistance. The primary sealing faces utilize silicon carbide (карбид кремния) for both the fixed and moving parts. This material provides exceptional hardness, excellent wear resistance, and good thermal conductivity, ensuring a stable seal face and extended service life. The metal structural components are manufactured from AISI 304 stainless steel, offering reliable corrosion resistance. The elastomeric element is made from NBR (Nitrile Butadiene Rubber), a versatile material known for its good resistance to oils, fuels, and a range of fluids within its temperature limits. The actuation force is provided by a cylindrical spring (циллиндрическая пружина) type design, ensuring consistent face loading.

The IN0300.120VPGG mechanical seal is engineered for applications requiring a balance of performance and cost-effectiveness. Its standardized design makes it a readily available option from the catalog of mechanical seals for maintenance and repair operations. When selecting this seal, engineers and technicians must cross-reference all provided dimensions of the mechanical seal with their equipment's housing and shaft specifications. Proper installation following manufacturer guidelines is essential to achieve the intended sealing integrity, reduce downtime, and enhance the operational efficiency of rotating machinery.
