Mechanical seal IN0140.BIA.BQVGG

The mechanical seal IN0140.BIA.BQVGG is a high-performance bellows-type sealing solution engineered for demanding industrial applications. This specific model belongs to the standardized IN560C/INBIA series, a comprehensive catalog of mechanical seals (каталог торцевих ущільнень) designed for reliability and interchangeability. Its construction utilizes a carefully selected combination of materials to ensure optimal operation under various conditions, including exposure to a wide range of fluids and moderate temperatures.

Key technical specifications define the precise dimensions of the mechanical seal (розміри торцевого ущільнення), ensuring a correct fit and function. The seal is designed for a shaft diameter (d1) of 14 mm. The stationary part features an external diameter (d7) of 30 mm and is manufactured from silicon carbide (карбид кремния), providing exceptional hardness and wear resistance against abrasive media. The metal components are constructed from AISI304 stainless steel, offering good corrosion resistance. The rotating face is made from graphite, ensuring a smooth, low-friction running surface against the silicon carbide. The dynamic sealing is achieved via an NBR (Nitrile) rubber bellows, which provides flexibility and effective secondary sealing. The overall seal length (L3) is 18.7 mm, with the moving part having an outer diameter (d3) of 24.5 mm. This specific configuration corresponds to the BIA seal grade, indicating its standardized design profile within the series.

The bellows-type (сильфонное) design is a significant feature, eliminating the need for a dynamic O-ring on the shaft, which reduces friction and allows for effective sealing even in applications with minor shaft runout or vibration. The material pairing of silicon carbide versus graphite creates a highly durable and self-lubricating primary sealing interface. This makes the IN0140.BIA.BQVGG suitable for a variety of pumps and rotating equipment handling water, light oils, coolants, and other non-aggressive fluids. When selecting a replacement or specifying a new seal, referencing the detailed dimensional parameters (розміри торцевого ущільнення) is critical for compatibility. This model's standardized design facilitates easy sourcing from the broader catalog of mechanical seals (каталог торцевих ущільнень), streamlining maintenance and procurement processes for operational engineers and maintenance technicians.
