DRH400 Self-Propelled Dredge with Steel Cables
Efficient dredging operations demand powerful, reliable, and durable slurry pumping equipment capable of performing under extreme conditions. Ace Centro Enterprises (ACE) delivers advanced dredging systems engineered for marine, mining, oil & gas, and environmental applications.
The DRAGFLOW DRH 400 is a heavy-duty self-propelled dredge equipped with steel cables and powered by the high-performance DRAGFLOW HY400. Designed for demanding projects, the DRH400 handles the toughest slurry environments with efficiency and reliability.
Advanced Slurry Pumping Equipment for Extreme Conditions
The DRH400 integrates a modular pontoon dredger structure that operates efficiently at virtually any depth, even in low pH slurry mixes. Built for durability and long operational life, it is ideal for:
Deep harbor dredging
Industrial sediment removal
Offshore maintenance projects
Heavy slurry transfer operations
Its steel cable system ensures operational stability and precision during continuous dredging operations.
High Density Slurry Pump Performance
At the core of the DRH400 is the HY400 hydraulic dredging pump, engineered specifically as a high density slurry pump capable of managing abrasive and heavy materials.
Key Technical Capabilities:
Handles slurry up to 1.7 specific gravity
Solids handling 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
Achieved dredging depths up to 300 meters for dam construction projects
The advanced agitator design allows efficient lifting and conveying of mud, slime, silt, sand, and gravel, ensuring continuous high-performance pumping.
Low operating speed minimizes wear and extends component lifespan, making it ideal for long-term heavy-duty operations.
Mine Tailings Dredging Solutions
For mine tailings dredging, the DRH400 delivers exceptional reliability and durability. All wear parts are manufactured from High Chrome Alloy, significantly extending the service life between spare part replacements.
The pump system includes:
Optional temperature sensor embedded in the motor
Optional moisture sensor in the oil chamber
Unique lip seal system with front deflector
Teflon layers resistant to both high and low pH conditions
High-precision machined components with grease injection points
These features ensure maximum protection against abrasive materials and corrosive environments commonly found in mining operations.
Oil Spill Recovery Dredger Applications
Environmental protection projects require equipment capable of rapid deployment and dependable performance. The DRH400 functions effectively as an oil spill recovery dredger, offering:
High-capacity pumping
Reliable operation in offshore environments
Modular design for easy transport and installation
Compatibility with hydraulic and electric submersible pump systems
This makes it suitable for oil spill control, waste pollution management, and offshore platform maintenance.
Canal Cleaning Dredger & Lake and Channel Dredging
ACE supplies self-propelled dredgers with telescopic and ladder dredge pump options to serve canal cleaning and waterway maintenance projects across the Arabian Gulf, Middle East, and Africa.
The DRH400 is highly effective for:
Canal cleaning dredging
Lake and channel dredging
