The mechanical seal IN0140.560С.BQVGG is a high-performance bellows-type sealing solution engineered for reliable operation in demanding industrial environments. This model belongs to the IN560C/INBIA series within the comprehensive catalog of mechanical seals, designed to ensure long-term integrity and prevent leakage in rotating shaft applications. Its construction utilizes a precise combination of advanced materials to achieve optimal wear resistance and chemical compatibility.
Key specifications define its application range and physical dimensions. The seal is configured for a shaft diameter (d1) of 14 mm. The external diameter of the fixed part (d7) is 25 mm, while the outer diameter of the moving part (d3) is 24.5 mm, with an overall seal length (L3) of 26.4 mm. These critical dimensions of the mechanical seal ensure a precise fit and correct installation within the designated housing. The material selection is central to its durability: the fixed part is manufactured from silicon carbide, offering exceptional hardness and corrosion resistance. The moving part consists of graphite, providing excellent self-lubricating properties and a reliable sealing face. The metal components are made from AISI304 stainless steel for structural strength and corrosion resistance, and the elastomeric bellows element is crafted from NBR (Nitrile rubber), ensuring flexibility and resilience against a wide range of oils and fluids.
As a bellows-type seal (сильфонное), the IN0140.560С.BQVGG eliminates the need for a dynamic O-ring, reducing friction and hang-up tendencies, which is particularly advantageous in applications involving viscous media or where shaft fretting is a concern. The seal grade 560C indicates its specific design configuration within the series, optimized for standardized pump and mixer models. When consulting the catalog of mechanical seals, this model stands out for its robust material pairing and precise engineering. Its primary applications include centrifugal pumps, agitators, and compressors across chemical processing, water treatment, and general industrial sectors where reliable shaft sealing is paramount. The precise dimensions of the mechanical seal, coupled with its high-grade material construction, guarantee consistent performance, reduced maintenance intervals, and enhanced equipment uptime.
