The mechanical seal IN0200.802.QQVGG is a robust double-tandem type seal engineered for demanding applications requiring enhanced sealing security and leak prevention. This model is a key component within the comprehensive CATALOG OF MECHANICAL SEALS / IN802 series, offering a reliable solution for rotating equipment. Its tandem configuration provides a primary and secondary sealing chamber, significantly increasing operational safety and environmental protection by containing potential leakage.

Constructed for durability and chemical resistance, the seal features stationary and rotating faces manufactured from silicon carbide (карбид кремния), a material renowned for its exceptional hardness, wear resistance, and stability in aggressive media. The metallic structural components are made from AISI304 stainless steel, ensuring corrosion resistance and structural integrity. The secondary elastomeric sealing element utilizes VITON (FKM) rubber, which delivers excellent performance across a wide temperature range and high compatibility with oils, fuels, and many chemicals.

Precise dimensional compatibility is critical for effective sealing. The IN0200.802.QQVGG is designed for a shaft diameter (d1) of 20 mm. The external diameter of the fixed part (d7) is 35 mm, while the outer diameter of the moving part (d3) measures 38 mm. The overall seal length (L3) is 39 mm. These specific **розміри торцевого ущільнення** ensure a proper fit within the seal chamber and correct alignment on the shaft, which is essential for optimal performance and service life. Consulting the detailed **каталог торцевих ущільнень** is recommended to verify exact housing dimensions and installation requirements.

This mechanical seal is suitable for a variety of industrial pumps, mixers, and compressors operating under challenging conditions where a single seal may be insufficient. The tandem design makes it applicable for handling hazardous, toxic, or expensive fluids, providing a reliable barrier. Its material composition allows it to perform in services involving moderate to high temperatures and a broad spectrum of aggressive fluids. When selecting a seal, the IN0200.802.QQVGG represents a professional choice for engineers prioritizing system safety, environmental compliance, and long-term reliability in critical sealing applications.
