Mechanical seal IN0200.BIA.BQVGG

The mechanical seal IN0200.BIA.BQVGG is a bellows-type sealing solution engineered for reliable operation in rotary shaft applications. This specific model belongs to the standardized IN560C/INBIA series, a comprehensive catalog of mechanical seals designed for interchangeability and performance. Its construction is defined by precise dimensional parameters, ensuring correct fit and function. The primary shaft diameter (d1) is 20 mm, with the moving part outer diameter (d3) at 34 mm and the fixed part outer diameter (d7) at 35 mm. The overall seal length (L3) is 21 mm. These critical dimensions of the mechanical seal must be verified against the equipment specifications prior to installation.

This seal utilizes a robust material combination to withstand demanding operational conditions. The stationary face is manufactured from silicon carbide, a material renowned for its exceptional hardness, wear resistance, and chemical inertness. The rotating face employs graphite, offering excellent self-lubricating properties and thermal conductivity for stable friction pair performance. The metal structural components are made from AISI 304 stainless steel, providing good corrosion resistance, while the elastomeric bellows element is constructed from NBR (Nitrile Butadiene Rubber), suitable for a wide range of fluids including oils, water, and certain chemicals.

The IN0200.BIA.BQVGG is classified under the BIA seal grade, indicating a balanced design and specific configuration for its application range. The bellows-type (сильфонное) design eliminates the need for a dynamic O-ring, reducing friction and hang-up tendencies, which is particularly advantageous in applications with minor shaft runout or vibration. This mechanical seal is typically applied in pumps, mixers, and compressors handling various non-aggressive media, where reliable shaft sealing is paramount to prevent leakage and ensure operational efficiency. Consulting the relevant catalog of mechanical seals is recommended for complete technical data, installation guidelines, and compatibility information to confirm suitability for your specific system requirements.
