The mechanical seal IN0250.120HBVPGG is a precision-engineered component from the IN120HB series, designed for reliable shaft sealing in rotary equipment such as pumps, mixers, and agitators. This model represents a specific configuration within the comprehensive catalog of mechanical seals, offering a balanced solution for a range of industrial fluid handling applications.

Constructed for a nominal shaft diameter (d1) of 25 mm, this seal features a robust cylindrical spring design, ensuring consistent face loading and stable performance under variable operational conditions. The primary sealing faces utilize a material combination of ceramic for the fixed part and graphite for the moving part. This pairing provides excellent wear resistance, low friction, and reliable operation with various compatible fluids. The metallic components are manufactured from AISI304 stainless steel, offering good corrosion resistance in many common industrial environments. The secondary elastomeric sealing element is made from NBR (Nitrile Butadiene Rubber), suitable for a wide range of oils, water, and other fluids within its temperature and chemical compatibility limits.

Critical installation dimensions are precisely defined. The external diameter of the fixed part (d7) is 40 mm, while the outer diameter of the moving part (d3) measures 44 mm. The overall seal length (L3) is 33.5 mm. These specific dimensions of the mechanical seal are crucial for correct housing fitment and interference-free operation, and they should be carefully verified against equipment specifications. The seal is classified under grade 120HB, indicating its standardized design and performance characteristics within its series.

When selecting from a catalog of mechanical seals, the IN0250.120HBVPGG provides a dependable option for standard-duty applications where its material compatibility aligns with the pumped medium. Its design prioritizes longevity and consistent sealing integrity, helping to minimize fluid leakage, reduce maintenance frequency, and protect equipment from damage. For optimal performance and service life, ensure proper installation, alignment, and that the operational environment is within the specified limits of its constituent materials.
