Mechanical seal IN0350.120HBVPGG

The mechanical seal IN0350.120HBVPGG is a precision-engineered component designed for reliable shaft sealing in a wide range of industrial rotary equipment, including pumps, mixers, and compressors. As part of the standardized IN120HB series featured in comprehensive mechanical seal catalogs, this model offers a proven balance of durability and performance for demanding fluid handling applications. Its construction is defined by a selection of materials and precise dimensions that ensure compatibility and long service life.

This seal is configured with a cylindrical spring type, providing consistent and uniform closing force for stable operation under variable conditions. The fixed sealing ring is manufactured from high-grade ceramic, offering exceptional hardness and superior resistance to abrasion and corrosion. The complementary moving ring is crafted from graphite, a material chosen for its excellent self-lubricating properties and thermal conductivity, which promotes stable face lubrication and heat dissipation. The metallic structural components are made from AISI304 stainless steel, ensuring robust construction and resistance to rust in many common industrial environments. The elastomeric elements utilize NBR (Nitrile Butadiene Rubber), which provides reliable static sealing and good resistance to oils and a wide range of fluids.

Critical installation dimensions are paramount for correct selection, and the IN0350.120HBVPGG provides clear specifications. It is designed for a nominal shaft diameter (d1) of 35 mm. The external diameter of the fixed part (d7) measures 50 mm, while the outer diameter of the moving part (d3) is 56 mm. The overall seal length (L3) is 43.5 mm. These precise dimensions of the mechanical seal must be carefully cross-referenced with the equipment housing and shaft specifications to guarantee a proper fit and optimal function. The seal is classified under the 120HB performance grade, indicating its suitability for specific pressure and velocity parameters.

When consulting a catalog of mechanical seals for a replacement or new design, the IN0350.120HBVPGG represents a reliable choice for standard pump applications where its material combination and dimensional accuracy are required. Its design prioritizes operational reliability, ease of installation, and interchangeability within its series. Proper selection based on the exact operating media, temperature, pressure, and shaft speed is essential to fully utilize the seal's engineered capabilities and ensure leak-free performance.
