DRH400 Self-Propelled Dredge with Steel Cables
Modern offshore and marine infrastructure projects require robust, high-capacity offshore dredging equipment capable of operating in harsh environments and handling abrasive slurry mixtures. Ace Centro Enterprises (ACE) provides advanced dredging systems designed for deep harbor, mining, oil & gas, and environmental applications across the Middle East and African markets.
At the core of its heavy-duty solutions is the DRAGFLOW DRH 400, a self-propelled dredge with steel cables engineered to deliver maximum performance and reliability in demanding offshore and port operations.
Engineered for Offshore Dredging Equipment Applications
The DRH400 is specifically designed to meet the challenges of offshore platforms, deep-sea operations, and industrial marine projects. Its steel cable configuration ensures:
Superior operational stability
Controlled dredging precision
Reliable anchoring in deep waters
Continuous heavy-duty performance
This makes it ideal for offshore terminals, oil platforms, and large-scale marine infrastructure works.
Port and Marina Dredging with Low pH Slurry Pump Capability
Ports and marinas often face sediment buildup combined with chemically aggressive slurry mixtures. The DRH400’s modular pontoon design allows operation at virtually any depth while handling low pH slurry mixes without compromising durability.
The system is powered by the high-performance DRAGFLOW HY400, engineered with specialized sealing technology that includes:
Unique lip seal system with front deflector
Teflon layers resistant to high and low pH conditions
High-precision machined components
Grease injection points for extended sealing life
Optional temperature and moisture sensors provide additional protection, ensuring safe and efficient operations in corrosive marine environments.
High Specific Gravity Slurry Pump Performance
The HY400 functions as a powerful high specific gravity slurry pump, capable of handling:
Slurry mixtures up to 1.7 specific gravity
Solids ranging from 20 mm to 120 mm (5 inches)
Flow rates up to 4000 m³/hr
Pumping distances up to 1500 meters, extendable with booster pumps
Dredging depths reaching 300 meters for dam construction projects
Its low operating speed reduces wear, extending component lifespan and minimizing maintenance downtime.
All wear parts are manufactured using High Chrome Alloy, ensuring extended service intervals even in highly abrasive environments.
Advanced Agitator Dredge Pump Technology
The advanced agitator system is central to the DRH400’s superior performance. The agitator dredge pump design enables efficient lifting and suspension of dense materials such as:
Mud
Slime
Silt
Sand
Gravel
This ensures consistent slurry flow and prevents sediment settlement, even in high-density conditions.
Supporting African Dredging Projects
Through its established sales and support network, ACE supplies self-propelled dredgers with telescopic and ladder pump configurations for African dredging projects, including:
Canal cleaning
Deep-sea dredging
Port expansion
Marina maintenance
Jetty and harbor rehabilitation
Lake and channel dredging
Dam and dike construction
Electric pump variants are available in both 50 Hz and 60 Hz, providing compatibility with regional power standards.
Italian Manufacturing Excellence
All pump castings are 100% manufactured in Italy, utilizing high-quality metallurgy and materials to guarantee durability and long-term operational reliability. The precision engineering ensures optimal sealing performance and structural integrity across demanding offshore and marine environments.
Conclusion
The DRH400 Self-Propelled Dredge with Steel Cables represents a comprehensive solution for offshore dredging equipment, port and marina dredging, low pH slurry pump applications, high specific gravity slurry pump operations, agitator dredge pump technology, and large-scale African dredging projects.
With its modular pontoon structure, powerful HY400 hydraulic pump, extended pumping range, and deep dredging capability, the DRH400 delivers exceptional strength, efficiency, and reliability for the world’s most demanding dredging challenges.
