Mechanical seal IN0220.4701.BVPGG

The mechanical seal IN0220.4701.BVPGG is a robust double-tandem type seal engineered for demanding applications requiring enhanced sealing security. As part of the comprehensive **каталог торцевих ущільнень** series IN4701, this model is designed to prevent leakage effectively in rotating shaft equipment such as pumps, mixers, and compressors. Its tandem configuration provides a dual-barrier sealing system, where the primary seal handles the pumped medium, and the secondary seal acts as a backup, significantly improving operational reliability and environmental safety.

This seal is constructed with a precise material composition to ensure durability and chemical compatibility. The fixed sealing face is manufactured from high-grade ceramic, offering exceptional hardness and wear resistance. The moving face utilizes graphite, providing excellent self-lubricating properties and a reliable sealing surface. The metal components are made from AISI304 stainless steel, ensuring corrosion resistance, while the elastomer bellows is crafted from NBR (Nitrile rubber), suitable for a wide range of fluids including oils, water, and certain chemicals. Critical **розміри торцевого ущільнення** are meticulously defined: it is designed for a shaft diameter (d1) of 22 mm. The external diameter of the fixed part (d7) is 37 mm, and the outer diameter of the moving part (d3) is 36 mm. The overall seal length (L3) is 49 mm, ensuring compatibility with standard housing dimensions.

The IN0220.4701.BVPGG is ideal for applications where a single mechanical seal may be insufficient, such as in handling hazardous, toxic, or expensive fluids. Its design minimizes the risk of unplanned downtime and protects equipment from damage due to leakage. When selecting a seal from the **каталог торцевих ущільнень**, these precise specifications allow for accurate interchangeability and replacement, guaranteeing optimal performance. Proper installation according to the specified **розміри торцевого ущільнення** is crucial for achieving the intended service life and sealing integrity. This mechanical seal represents a reliable solution for industrial maintenance and engineering projects demanding high-performance sealing technology.
