Mechanical seal IN0220.680W.QQVGG

**Mechanical Seal IN0220.680W.QQVGG**

The IN0220.680W.QQVGG is a high-performance mechanical seal engineered for demanding industrial applications. As part of the comprehensive **каталог торцевих ущільнень** for the IN680W series, this model represents a robust sealing solution designed for reliability and extended service life. Its construction is based on a metal bellows design, providing superior performance in challenging environments where conventional pusher-type seals may be less effective.

**Design and Construction Features**

This seal is classified as a metal bellows type, which eliminates the need for dynamic elastomeric components, thereby reducing the risk of hang-up and improving response to axial and angular shaft movements. The primary sealing faces utilize silicon carbide (карбид кремния) for both the stationary and rotating parts. This material pairing ensures exceptional wear resistance, high thermal conductivity, and excellent chemical inertness against a wide range of aggressive media. The secondary sealing is handled by a VITON elastomer, known for its superior resistance to high temperatures, oils, and many chemicals. The structural metal components are manufactured from AISI304 stainless steel, providing good corrosion resistance and mechanical strength.

**Precise Engineering and Dimensions**

The precise **розміри торцевого ущільнення** are critical for correct installation and optimal performance. The IN0220.680W.QQVGG is designed for a nominal shaft diameter (d1) of 22 mm. The external diameter of the stationary part (d7) measures 43 mm, while the outer diameter of the moving part (d3) is 44 mm. The overall seal length (L3) is 46.5 mm. These exact dimensions ensure a proper fit within the seal chamber and guarantee the correct face loading for efficient sealing.

**Applications and Benefits**

This mechanical seal is suitable for a variety of pumps and rotating equipment handling water, light chemicals, and other non-abrasive fluids. The 680W seal grade indicates a specific configuration optimized for balanced performance. The metal bellows design makes it particularly advantageous in applications involving crystallizing fluids or where shaft fretting is a concern. Its robust material combination ensures durability, minimizes maintenance downtime, and enhances the overall operational safety of the equipment.

For accurate selection and interchangeability, always consult the official **каталог торцевих ущільнень** and verify all installation dimensions, including the specified **розміри торцевого ущільнення**, prior to procurement and assembly. The IN0220.680W.QQVGG offers a dependable sealing solution where mechanical integrity and long-term performance are paramount.
