**Mechanical Seal IN0300.802.QQVGG**

The IN0300.802.QQVGG is a high-performance double (tandem) mechanical 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** for the IN802 series, representing a robust solution for rotating equipment where single seals may be insufficient.

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, providing reliable corrosion resistance. The secondary sealing element utilizes VITON elastomer, ensuring compatibility with a wide range of oils, fuels, and many chemical fluids, even at elevated temperatures.

Precise **розміри торцевого ущільнення** are critical for correct installation and optimal performance. This seal is designed for a shaft diameter (d1) of 30 mm. The external diameter of the fixed part (d7) is 45 mm, while the outer diameter of the moving part (d3) measures 48 mm. The overall seal length (L3) is 39 mm. These standardized dimensions facilitate straightforward selection and replacement from technical catalogs.

The tandem configuration places two sets of sealing faces in a series arrangement along the shaft. This design is primarily employed to create a reliable barrier system, often allowing for a buffer or barrier fluid between the seals to contain hazardous, abrasive, or valuable process fluids. It significantly increases operational safety and environmental protection, making it suitable for pumps handling volatile organic compounds, dangerous chemicals, or applications where zero external leakage is mandated.

As a dedicated **торцевое уплотнение** (mechanical face seal), model IN0300.802.QQVGG is applicable in various industrial sectors, including chemical processing, petrochemicals, pharmaceuticals, and refining. Its robust material combination and tandem design ensure extended service life, reduced maintenance downtime, and reliable operation under challenging conditions, providing a secure and efficient sealing solution for critical pump assets.
