Efficient dam and reservoir maintenance is essential for water storage capacity, flood control, and long-term infrastructure sustainability. Sediment buildup can significantly reduce operational efficiency, which is why powerful dredging technology is required. The Dragflow HY300 / HY400 Hydraulic Pump is a high-performance dam and reservoir cleaning pump, designed to remove heavy silt, sludge, and sediment with maximum efficiency.
Manufactured by Dragflow, this pump series is engineered for demanding dredging applications in water infrastructure, mining, and environmental restoration projects worldwide.
Advanced Solution for Dam and Reservoir Maintenance
Dams and reservoirs accumulate large volumes of fine and coarse sediment over time, reducing water storage capacity and affecting performance. The HY300 / HY400 series is specifically designed to restore capacity through efficient dredging and slurry transport.
It is widely used in:
Dam desilting and maintenance
Reservoir cleaning and restoration
Lake and canal dredging
River sediment removal
Water treatment and infrastructure maintenance
