**Mechanical Seal IN0160.109K.QQVGG: High-Performance Bellows Seal for Demanding Applications**

The IN0160.109K.QQVGG is a precision-engineered mechanical seal designed for reliable shaft sealing in pumps, mixers, and other rotary equipment. As part of the comprehensive **каталог торцевих ущільнень (catalog of mechanical seals)** IN109K series, this model represents a robust solution for handling aggressive media and challenging operating conditions. Its construction prioritizes chemical resistance, thermal stability, and long-term operational integrity.

**Technical Specifications and Design Features**

This seal is configured as a **сильфонное (bellows-type)** seal, which eliminates the need for a dynamic O-ring, reducing friction and enabling effective performance in applications with minor shaft runout or misalignment. The critical sealing faces are manufactured from **карбид кремния (silicon carbide)** for both the fixed and moving parts. This material pairing ensures exceptional wear resistance, high thermal conductivity, and superior corrosion resistance against a wide range of acids, alkalis, and abrasive slurries.

The metal structural components are made from **AISI304 stainless steel**, providing good general corrosion resistance and structural strength. The secondary sealing element utilizes **VITON (FKM) elastomer**, known for its excellent compatibility with hydrocarbons, oils, and many solvents, as well as its high-temperature performance. Precise **розміри торцевого ущільнення (mechanical seal dimensions)** are critical for proper installation and function: the shaft diameter (d1) is 16 mm, the external diameter of the fixed part (d7) is 30.95 mm, and the outer diameter of the moving part (d3) is 28.5 mm. The overall seal length (L3) is 25.4 mm, and the model is classified under seal grade **109K**.

**Application and Benefits**

The IN0160.109K.QQVGG mechanical seal is engineered for applications where standard elastomer-based seals may fail. Its primary benefits include reliable operation in environments with crystallizing or viscous fluids, thanks to the bellows design. The use of silicon carbide faces minimizes leakage and extends mean time between failures (MTBF), reducing maintenance costs and downtime. This seal is suitable for various industrial sectors, including chemical processing, petrochemical, pharmaceutical, and water treatment.

When selecting a seal from the **каталог торцевих ущільнень**, accurate verification of all **розміри торцевого ущільнення** against the equipment's shaft and housing dimensions is essential to ensure a correct fit and optimal sealing performance. The IN0160.109K.QQVGG offers a dependable, high-grade sealing solution for rotating shafts where durability and chemical resistance are paramount.
