Heavy sediment dredging requires equipment that can break down compacted materials, maintain stable slurry flow, and operate reliably in highly abrasive environments. The Dragflow HY300 / HY400 Hydraulic Pump is specifically engineered as a powerful agitator pump for heavy sediment, delivering high performance in mining, dredging, and industrial applications.
Designed and manufactured in Italy, this hydraulic pump series is part of the advanced dredging solutions developed by Dragflow, a global leader in submersible pumping technology for over 25 years.
Overview of HY300 / HY400 Hydraulic Pump
The HY300 and HY400 models are built for extreme-duty operations where conventional pumps fail. These pumps combine hydraulic power with an integrated agitation system, making them ideal for handling dense sediment layers, slurry mixtures, and high-solid content materials.
They are widely used in:
River and lake dredging
Mining slurry extraction
Port and harbour maintenance
Industrial waste and sediment handling
Beach nourishment and reclamation projects
