The mechanical seal IN0350.680W.QQVGG is a precision-engineered component designed for demanding sealing applications in pumps, mixers, and other rotary equipment. This model belongs to the standardized IN680W seal grade series, a key part of any comprehensive mechanical seals catalog. Its robust metal bellows construction ensures reliable performance under conditions of axial shaft movement, vibration, and temperature fluctuations.

Constructed for a shaft diameter (d1) of 35 mm, this seal features a compact design with a total seal length (L3) of 46.5 mm. The critical sealing faces utilize silicon carbide (карбид кремния) for both the fixed and moving parts, providing exceptional resistance to abrasion, corrosion, and thermal shock, which guarantees extended service life and minimal leakage. The secondary sealing element is made from VITON elastomer, offering excellent chemical compatibility and high-temperature stability. The structural metal components are fabricated from AISI304 stainless steel, ensuring overall corrosion resistance and mechanical integrity.

Key dimensional parameters are critical for correct installation and interchangeability. The external diameter of the fixed part (d7) is 58 mm, while the outer diameter of the moving part (d3) measures 57 mm. These precise dimensions of the mechanical seal must be verified against the equipment housing and gland plate specifications to ensure a proper fit. When consulting the mechanical seals catalog for a replacement or upgrade, confirming these exact measurements is essential for operational success.

The IN0350.680W.QQVGG is suitable for a wide range of industrial fluids, including water, light chemicals, and various process media, where a durable and leak-free seal is paramount. Its metal bellows type eliminates the need for a dynamic O-ring on the shaft, reducing hang-up and enabling effective sealing in applications with crystallizing or viscous fluids. This model represents a reliable solution for maintenance engineers and OEM designers seeking a high-performance mechanical seal with clearly defined specifications and proven material compatibility.
