The mechanical seal IN0250.90BQQVGG is a precision-engineered component designed for reliable shaft sealing in demanding industrial applications. This model belongs to the comprehensive CATALOG OF MECHANICAL SEALS / IN90B series, representing a standardized solution for pumps and rotating equipment. Its construction is defined by critical dimensions and material selections that ensure longevity and consistent performance under various operational conditions.

Key specifications of the IN0250.90BQQVGG include a shaft diameter (d1) of 25 mm. The seal features a fixed part with an external diameter (d7) of 40 mm and a moving part with an outer diameter (d3) of 39 mm, with an overall seal length (L3) of 33 mm. These precise **розміри торцевого ущільнення** are crucial for correct installation and optimal function within the designated housing. The seal is classified as type 90B, indicating a design **с прижимным кольцом** (with a clamping ring), which facilitates secure mounting and alignment on the shaft.

Material selection is paramount for seal durability. Both the fixed and moving sealing faces are manufactured from silicon carbide (карбид кремния), a material renowned for its exceptional hardness, wear resistance, and chemical inertness. This pairing ensures a stable, low-friction running surface, minimizing leakage and power consumption. The structural metal components are made from AISI 304 stainless steel, providing excellent corrosion resistance. The secondary sealing element utilizes NBR (Nitrile Butadiene Rubber), a versatile elastomer offering good compatibility with a wide range of oils, water, and fluids.

This mechanical seal is engineered for applications where reliable separation of fluids is required, such as in centrifugal pumps, mixers, and compressors. The combination of robust materials and precise engineering makes the IN0250.90BQQVGG suitable for handling water, coolants, light chemicals, and various industrial process fluids. When selecting a seal, referencing the detailed **каталог торцевих ущільнень** is essential to match the exact model, like the IN0250.90BQQVGG, to the specific equipment requirements, ensuring proper fitment and operational reliability.
