A modern high efficiency hydraulic dredger is essential for large-scale dredging projects that demand maximum productivity, low operating cost, and reliable performance in harsh environments. The DRH400 self-propelled dredge with steel cables is engineered to deliver outstanding efficiency in heavy-duty dredging applications. The DRAGFLOW DRH400 dredger combines advanced hydraulic power with robust construction to ensure continuous and effective material removal.
DRH400 – Advanced High Efficiency Hydraulic Dredger
Ace Centro Enterprises (ACE) delivers cutting-edge dredging solutions featuring a powerful high efficiency hydraulic dredger designed for marine, mining, and industrial operations. The DRAGFLOW DRH 400 dredge with steel cables is equipped with the high-performance DRAGFLOW HY400 hydraulic dredging pump, engineered to maximize output while minimizing energy consumption and wear.
This system is designed to deliver exceptional dredging efficiency through an optimized hydraulic configuration and advanced agitator technology. It effectively breaks, mixes, and transports dense slurry materials such as mud, sand, gravel, and silt with high consistency and speed.
The modular pontoon design and self-propelled structure allow flexible deployment in deep water, offshore environments, and confined dredging zones. It performs reliably even in low pH and high-abrasion conditions, making it suitable for continuous industrial operation.
ACE also supplies a wide range of electric and hydraulic submersible dredge pumps used in harbor dredging, sand reclamation, mining tailings, wastewater treatment, oil spill response, and major infrastructure projects across the Middle East and Africa.
