Dragflow DRH400 – High-Performance Dredging Solution
An efficient excavator dredge pump is essential for contractors handling slurry, sediment, and high-density materials in marine and mining environments. The Dragflow DRH400, supplied by Ace Centro Enterprises (ACE), delivers exceptional dredging performance through its advanced hydraulic technology and robust structural design.
This self-propelled dredge with steel cables is powered by the heavy-duty Dragflow HY400 hydraulic dredging pump, engineered to handle the toughest dredging operations with reliability and efficiency. Its modular pontoon design ensures stable operation at various depths, including environments with low pH slurry mixtures.
Built for Demanding Applications
ACE offers a complete range of electric and hydraulic submersible dredge pumps that can be integrated into dredging systems or adapted for excavator-mounted configurations. These systems are ideal for:
Harbor and port dredging
Canal and marina cleaning
Sand reclaiming
Mine tailing removal
Quarrying and aggregate processing
Waste pollution control
Heavy slurry pumping
Oil spill response
Tunneling and bentonite pumping
Sewage pumping
