**Product Description: Mechanical Seal IN0140.120HBVPGG**

The IN0140.120HBVPGG is a precision-engineered mechanical seal belonging to the IN120HB series, a comprehensive line of sealing solutions detailed in our extensive catalog of mechanical seals. This model is designed for reliable operation in a wide range of rotary equipment, including pumps, mixers, and compressors, where it effectively prevents fluid leakage along the shaft.

**Construction and Material Specifications**
This seal features a robust cylindrical spring design, ensuring consistent sealing face loading and stable performance under variable operational 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 premium graphite, providing excellent self-lubricating properties and thermal conductivity for smooth, low-friction operation. The metallic components are constructed from AISI304 stainless steel, guaranteeing structural integrity and corrosion resistance in demanding environments. The elastomeric elements are made from NBR (Nitrile Butadiene Rubber), a material selected for its good compatibility with oils, water, and a range of industrial fluids.

**Critical Dimensional Data**
Precise **розміри торцевого ущільнення (mechanical seal dimensions)** are paramount for correct installation and optimal function. The IN0140.120HBVPGG is engineered for a nominal shaft diameter (d1) of 14 mm. The external diameter of the fixed part (d7) measures 25 mm, while the outer diameter of the moving part (d3) is 31 mm. The overall seal length (L3) is 29.5 mm. These standardized dimensions facilitate easy selection and replacement from the **каталог торцевих ущільнень (catalog of mechanical seals)**, ensuring compatibility with standard housing designs.

**Application and Performance**
As a member of the seal grade 120HB, this unit is built for general industrial service. The combination of ceramic, graphite, and stainless steel with an NBR elastomer makes it suitable for applications involving water, light oils, coolants, and other non-aggressive media. The cylindrical spring type provides a reliable axial force, maintaining seal face contact during shaft excursions and vibration. Its construction ensures long service life, reduced maintenance downtime, and enhanced equipment reliability.

For accurate integration, always verify the specific dimensional parameters and material compatibility with your application's operational pressure, temperature, and fluid characteristics. The IN0140.120HBVPGG represents a dependable and widely applicable sealing solution from our professional portfolio.
