dredging cutter pump Applications

  • Dredging

    Dragflow dredging equipments are widely used in underwater excavation and dredging activities. Dragflow pumps are design to work both in shallow seas, or fresh water areas, as well as in deep water applications. The unique design of dredging cutters allows Dragflow equipments to reach an exceptional solid concentration also in presence of very compact soil.

    Cutting efficiency is greatly affected by variability in soil density, hardness, lithology, and sediment particle size distribution. All of these factors create slurry of variable makeup and density. If the dredge pump works at a constant speed, the slurry will have a variable flow velocity, which is undesirable and potentially dangerous. If the velocity is too low, there is a risk of sandouts in the pipeline. If the velocity is too high, the pump will wear and be inefficient. Traditional velocity flowmeters with wetted parts are prone to wear, causing measurement inaccuracies, and require frequent, costly replacements
