The mechanical seal IN0220.112VPGG is a precision-engineered component designed for reliable shaft sealing in rotary equipment. This model belongs to the IN112 series within the comprehensive catalog of mechanical seals, representing a standardized solution for a wide range of industrial applications. Its construction ensures effective containment of fluids, prevention of leaks, and long-term operational stability in pumps, mixers, and similar machinery.

This seal is configured as a type with a clamping ring (с прижимным кольцом), which facilitates secure installation and maintains proper alignment on the shaft. The critical sealing faces are manufactured from silicon carbide (карбид кремния) for both the fixed and moving parts. This material selection provides exceptional hardness, excellent wear resistance, and good chemical inertness, making the seal suitable for handling abrasive media, aggressive fluids, and high-purity applications. The metal structural components are constructed from AISI304 stainless steel, offering corrosion resistance and mechanical strength. The secondary sealing element is made from NBR (Nitrile Butadiene Rubber), a versatile elastomer known for its good resistance to oils, fuels, and a range of industrial fluids.

The precise dimensions of the mechanical seal are key to its correct selection and function. The primary shaft diameter (d1) for installation is 22 mm. The external diameter of the fixed part (d7) measures 37 mm, while the outer diameter of the moving part (d3) is 36 mm. The overall seal length (L3) is 37.5 mm. These specific dimensions of the mechanical seal must be carefully cross-referenced with the housing and shaft specifications to ensure a proper fit. The seal is classified under grade 112, indicating its standardized design profile within the product line.

When consulting the catalog of mechanical seals, the IN0220.112VPGG is identified as a robust and versatile unit. Its design is optimized for applications where dependable sealing performance is required under demanding conditions. The combination of silicon carbide faces and stainless steel metal parts ensures durability, while the standardized dimensions allow for straightforward replacement and interchangeability in existing systems. Proper installation according to the specified dimensions guarantees optimal seal face loading and extended service life, minimizing downtime and maintenance costs.
