Advanced Marine Dredging Equipment for Mining and Oil & Gas Applications

The growing demand for reliable marine dredging equipment across ports, offshore facilities, and industrial waterways has driven the need for powerful and adaptable dredging solutions. Ace Centro Enterprises (ACE) responds to this demand by delivering high-performance dredging systems designed for mining dredger operations and oil and gas dredging projects in some of the world’s most challenging environments.

Among its flagship solutions is the DRAGFLOW DRH400 self-propelled dredge with steel cables, engineered to provide superior performance, durability, and operational efficiency.

DRH400 Self-Propelled Dredge with Steel Cables

The DRH400 is a heavy-duty cable dredger specifically developed for deep harbor dredging and industrial slurry handling. Designed for continuous operation, this dredge is equipped with the powerful DRAGFLOW HY400 hydraulic submersible dredge pump, enabling it to manage tough materials with ease.

Its modular pontoon dredger design allows for fast transportation and flexible assembly, making it suitable for both shallow and deep-water applications. The system performs reliably at any depth and is highly resistant to low-pH slurry mixes commonly encountered in mining and oil & gas environments.

High-Efficiency Submersible Dredge Pump Technology

At the core of the DRH400 is Dragflow’s advanced submersible dredge pump, engineered around a high-performance agitator system. This design allows the pump to efficiently loosen and transport dense slurry materials such as mud, slime, silt, sand, and gravel.

Key Performance Capabilities:

Slurry handling up to 1.7 specific gravity

Solids handling from 20 mm to 120 mm (5 inch)

Flow rates reaching 4000 m³/hr

Pumping distances up to 1500 meters, extendable with booster pumps

Proven dredging depths up to 300 meters

The pump’s low operating speed significantly reduces wear, extending service life and lowering operational costs.

Designed for Harsh Industrial Conditions

Dragflow dredging pumps are built with durability as a core priority. All wear components are manufactured from High Chrome Alloy, ensuring excellent resistance to abrasion in heavy slurry applications.

Advanced protection features include:

Best-in-class lip seal system with front deflector

Teflon layers for resistance to high and low pH conditions

Precision-machined components for superior sealing performance

Optional motor temperature sensor and oil chamber moisture sensor

These features make the DRH400 an ideal choice for long-term mining dredger operations and continuous oil and gas dredging activities.

Versatile Applications Across Industries

ACE supplies a full range of electric and hydraulic dredging solutions to support diverse industrial needs, including:

Marine and harbor dredging

Mining tailings and quarry dredging

Oil and gas dredging at offshore platforms

Sand reclaiming and land reclamation

Waste pollution control and heavy slurry pumping

Tunneling and bentonite pumping

Sewage pumping and water management

Construction of dams, dikes, canals, and channels

Electric pump options are available in both 50 Hz and 60 Hz, ensuring compatibility with regional power standards.

Regional Supply Expertise in the Middle East & Africa

Through its established sales network in the Arabian Gulf, Ace Centro Enterprises supplies self-propelled dredgers with telescopic and ladder-mounted pump configurations across the Middle East and Africa. These systems are widely deployed for canal cleaning, deep-sea dredging, and offshore works at ports, jetties, marinas, and oil & gas installations.

All Dragflow pump castings are 100% manufactured in Italy, using premium metallurgy to deliver long service life and reliable performance in demanding operating conditions throughout the UAE and surrounding regions.

Conclusion

The DRH400 self-propelled dredge with steel cables stands out as a robust and versatile solution in the field of marine dredging equipment, offering proven performance for mining dredger applications and oil and gas dredging projects. Backed by Ace Centro Enterprises’ regional expertise and Dragflow’s Italian engineering, the DRH400 delivers efficiency, durability, and reliability where it matters most.
