Mechanical seal IN0250.502B.QQVGG

The mechanical seal model IN0250.502B.QQVGG is a high-performance bellows-type sealing solution engineered for demanding industrial applications. As a part of the comprehensive CATALOG OF MECHANICAL SEALS / IN502B, this unit is designed to ensure reliable operation and extended service life in pumps and rotating equipment. Its construction adheres to precise dimensional standards, with critical **розміри торцевого ущільнення** including a shaft diameter (d1) of 25 mm, an external diameter of the fixed part (d7) at 40 mm, and an overall seal length (L3) of 27 mm. These exact specifications guarantee a proper fit and optimal sealing performance.

This seal incorporates a robust material configuration for superior durability. The primary sealing faces utilize silicon carbide (карбид кремния) for both the fixed and moving parts, providing exceptional resistance to abrasion, corrosion, and thermal shock. The secondary elastomeric seal is made from VITON, offering excellent chemical compatibility and stability across a wide temperature range. The structural metal components are fabricated from AISI304 stainless steel, ensuring corrosion resistance and mechanical strength. The bellows design (сильфонное) accommodates axial shaft movement and vibration, maintaining consistent face contact and sealing integrity.

The IN0250.502B.QQVGG mechanical seal is ideal for applications in chemical processing, petrochemical, and general industrial sectors where handling aggressive fluids is common. Its 502B seal grade indicates a specific design profile optimized for balanced performance. When selecting components from any **каталог торцевих ущільнень**, attention to these detailed material and dimensional parameters is crucial for system compatibility and longevity. This model represents a reliable choice for maintenance and OEM applications requiring a precise, durable, and chemically resistant sealing assembly.
