Mechanical seal IN0140.301MVPGG

The mechanical seal IN0140.301MVPGG is a bellows-type sealing unit designed for reliable operation in rotary equipment such as pumps, mixers, and compressors. As part of the comprehensive **каталог торцевих ущільнень** for the IN301 series, this model is engineered to precise dimensional standards, ensuring compatibility and easy integration into existing systems. Its construction utilizes a robust material combination to withstand demanding operational environments.

Key technical specifications define the exact **розміри торцевого ущільнення** for correct installation. The seal is configured for a shaft diameter (d1) of 14 mm. The external diameter of the fixed part (d7) is 28.5 mm, while the outer diameter of the moving part (d3) measures 28 mm. The overall seal length (L3) is 13 mm. These critical dimensions guarantee a proper fit within the seal chamber, preventing leakage and ensuring stable performance.

Component material selection is central to the seal's durability and function. The fixed sealing face is manufactured from ceramic, offering exceptional hardness and wear resistance against abrasive media. The mating rotating face consists of graphite, providing a self-lubricating quality and excellent compatibility with the ceramic surface for a consistent seal. The metal structural components are made from AISI304 stainless steel, which provides corrosion resistance. The secondary sealing element is an NBR (Nitrile Butadiene Rubber) bellows, offering flexibility and reliable static sealing across a wide range of temperatures and fluids, including oils and water.

The IN0140.301MVPGG mechanical seal is classified under seal grade 301, indicating its standardized design within the product line. The bellows-type design eliminates the need for a dynamic O-ring on the shaft, reducing friction and hang-up, which is particularly advantageous in applications involving viscous fluids or where shaft fretting is a concern. This model is suitable for general industrial service in chemical, water treatment, and general manufacturing processes where reliable shaft sealing is paramount. When consulting the **каталог торцевих ущільнень**, the precise **розміри торцевого ущільнення** and material specifications of the IN0140.301MVPGG facilitate accurate selection and replacement, minimizing downtime and ensuring long-term sealing integrity.
