The mechanical seal IN0250.120CVPGG is a precision-engineered component designed for reliable shaft sealing in rotary equipment such as pumps, mixers, and compressors. This model belongs to the standardized IN120C series, a comprehensive catalog of mechanical seals (каталог торцевих ущільнень) known for their robust construction and consistent performance in various industrial fluid handling applications. Its design ensures effective containment of process media, preventing leakage and protecting equipment integrity.

Constructed from a carefully selected combination of materials, the seal offers durability and chemical compatibility. The primary sealing face is formed by a stationary ceramic ring, providing excellent wear resistance and hardness. The rotating face is composed of graphite, a self-lubricating material that ensures smooth operation and reliable sealing contact with minimal friction. The metal components, including the spring housing, are manufactured from AISI304 stainless steel, offering good corrosion resistance. The secondary elastomeric sealing element is made from NBR (Nitrile Butadiene Rubber), suitable for a wide range of oils, water, and many industrial fluids.

The precise dimensions of the mechanical seal IN0250.120CVPGG are critical for correct installation and function. It is engineered for a shaft diameter (d1) of 25 mm. The external diameter of the fixed part (d7) is 36 mm, while the outer diameter of the moving part (d3) measures 40 mm. The overall seal length (L3) is 26.5 mm. These specific dimensions of the mechanical seal (розміри торцевого ущільнення) must be verified against the equipment specifications to ensure a proper fit. The actuation force is provided by a cylindrical spring, a design known for its consistent loading and reliable performance across a wide range of operational conditions, including potential shaft run-out.

This seal is classified under the 120C seal grade, indicating its standardized design configuration within the product line. Its application is typical for general industrial services where the media and operating conditions are compatible with its material construction. Key benefits include extended service intervals, reduced maintenance downtime, and effective leakage control. When selecting from the catalog of mechanical seals, the IN0250.120CVPGG represents a balanced solution for standard-duty applications requiring a seal with a 25 mm bore, combining proven materials and a dependable cylindrical spring design for long-term sealing performance.
