DRH400 Self-Propelled Dredge with Steel Cables
In today’s demanding industrial environments, reliable and high-performance marine dredging equipment is essential for efficient operations. Ace Centro Enterprises (ACE) delivers heavy-duty cable dredgers designed for deep harbor, mining, and offshore applications.
At the forefront of its product range is the DRAGFLOW DRH 400, a powerful self-propelled dredge with steel cables, engineered to tackle the most challenging dredging conditions across marine, mining, and oil & gas sectors.
Heavy-Duty Marine Dredging Equipment for Extreme Conditions
The DRH400 is purpose-built for continuous operation in harsh environments, including:
Deep harbor dredging
Offshore oil terminal maintenance
Port and marina construction
Industrial sediment removal
Its rugged steel cable system provides enhanced stability and operational control, making it an ideal solution for harbor dredging solutions requiring precision and strength.
Advanced Mining Dredger Capabilities
As a high-performance mining dredger, the DRH400 is engineered to handle abrasive slurries and heavy solids with ease. The system is equipped with the powerful DRAGFLOW HY400, a hydraulic submersible dredge pump designed for medium to high specific gravity materials.
Key Performance Capabilities:
Handles slurry up to 1.7 specific gravity
Solids handling 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 up to 300 meters in dam construction projects
This makes it highly suitable for mine tailings removal, quarry operations, and mineral extraction projects.
Reliable Oil and Gas Dredging Solutions
In the oil and gas sector, dredging operations demand durability, corrosion resistance, and consistent performance. The DRH400’s modular pontoon design ensures flexibility in deployment at offshore platforms, jetties, and oil terminals.
Its advanced sealing system includes:
Unique lip seal with front deflector
Teflon layers resistant to high and low pH
High-precision machined components
Grease injection points for extended seal life
Optional safety features include:
Temperature sensor embedded in the motor
Moisture sensor in the oil chamber
These features make it a trusted choice for oil and gas dredging applications in aggressive slurry and marine environments.
Efficient Sand Reclaiming Dredger
For aggregate recovery and sand reclamation projects, the DRH400 performs efficiently in:
Sand reclaiming
Bentonite pumping
Water pumping
Waste pollution control
Heavy slurry pumping
All wear parts are manufactured using High Chrome Alloy, ensuring extended operational life and reduced downtime between spare part changes.
Electric pump versions are available in both 50 Hz and 60 Hz configurations, offering flexibility for international projects.
Modular Pontoon Design for Maximum Flexibility
The DRH400’s modular pontoon dredger structure offers:
Easy transportation and site assembly
Adaptability for remote and confined areas
Compatibility with telescopic and ladder dredge pump options
Seamless integration with booster pump systems
Through its strong sales presence in the Arabian Gulf, Middle East, and African markets, ACE also supplies self-propelled dredgers tailored for canal cleaning, deep-sea dredging, marinas, ports, and offshore infrastructure projects.
Italian Engineering Excellence
All pump castings are 100% manufactured in Italy, using premium metallurgy and high-quality materials to ensure long component life and superior performance. The advanced agitator design allows effective lifting and conveying of mud, slime, silt, sand, and gravel, even in demanding operational environments.
Conclusion
The DRH400 Self-Propelled Dredge with Steel Cables represents a complete solution for marine dredging equipment, mining dredger operations, oil and gas dredging, sand reclaiming dredger projects, and comprehensive harbor dredging solutions.
With its powerful HY400 hydraulic dredging pump, modular pontoon design, extended pumping distances, and deep operational capability, the DRH400 delivers reliability, strength, and efficiency for the world’s toughest dredging challenges.
