Deep Harbor Dredging Solutions with Modular Pontoon Dredger Technology
Modern marine infrastructure demands efficient, reliable, and heavy-duty dredging equipment capable of operating in extreme conditions. For deep harbor dredging projects across ports, marinas, canals, and offshore facilities, Ace Centro Enterprises (ACE) delivers proven solutions through its advanced modular pontoon dredger systems equipped with high-performance submersible dredge pumps.
One of the most powerful offerings in this category is the DRAGFLOW DRH400 self-propelled dredge with steel cables, designed to meet the toughest dredging challenges in marine, mining, and oil & gas industries.
DRH400 Self-Propelled Dredge with Steel Cables
The DRH400 is a heavy-duty cable dredger engineered for deep harbor dredging operations where reliability, depth capability, and slurry handling performance are critical. This self-propelled dredge is powered by the DRAGFLOW HY400 hydraulic submersible dredge pump, enabling continuous operation even in aggressive slurry environments and low-pH mixtures.
Thanks to its modular pontoon dredger design, the DRH400 can be easily transported, assembled, and deployed at varying dredging depths, making it an ideal solution for large-scale harbor maintenance and reclamation projects.
High-Performance Submersible Dredge Pump Technology
At the heart of the DRH400 system is Dragflow’s advanced submersible dredge pump, engineered to handle medium to high-density slurry mixtures such as mud, slime, silt, sand, and gravel.
Key Pump Capabilities:
Handles slurry specific gravity up to 1.7
Solids handling capacity from 20 mm up to 120 mm (5 inch)
Flow rates up to 4000 m³/hr
Pumping distances up to 1500 meters, extendable with booster pumps
Achieved dredging depths of up to 300 meters in dam construction projects
The low operating speed of the pump reduces wear and tear, extending component life and minimizing downtime during long dredging campaigns.
Built for Durability and Extreme Conditions
Dragflow dredging pumps are manufactured with precision-machined components and premium metallurgy. All wear parts are made from High Chrome Alloy, ensuring extended service life even in abrasive environments.
Advanced sealing systems include:
Best-in-class lip seal technology
Front deflector to block fine materials
Teflon layers resistant to high and low pH conditions
Grease injection points for long-term sealing performance
Optional temperature sensors in the motor and moisture sensors in the oil chamber provide added protection and operational safety.
