DK550 Cutter Suction Dredger

Beyond its 1250KW power core, the DK550 Cutter Suction Dredger Ship is a precision instrument designed to deliver continuous, high-volume output with the lowest operational cost per cubic meter.

● Extreme 3000m Discharge Reach: Equipped with a specialized WN450 high-head pump, the DK550 can transport material up to 3 kilometers without the need for a booster station, significantly lowering your initial capital investment and operational costs.

● Dual-Engine Synergetic Power: Features a 1250KW main engine for the slurry pump and a 456KW auxiliary engine dedicated to the hydraulic system. This separation ensures 100% torque for the 1800mm cutter head even when the pump is operating at maximum capacity.

● Precision Hydraulic Control: Utilizing a centralized one-man control system with high-end Vickers-style (T6ED series) pumps, the DK550 offers smooth, simultaneous operation of the ladder, swing winches, and spuds.

● Heavy-Duty Maritime Construction: With a 43.5m overall length and reinforced 25mm thick spuds, the DK550 provides a stable platform for 14-meter deep-water dredging in challenging river and coastal environments.

Core technical parameters

FAQ

Q1: How does the DK550 Cutter Suction Dredger Ship maintain a 3000m discharge distance without a booster pump?

A: It’s all about the synergy between the 1250KW high-torque engine and the WN450 specialized pump. By optimizing the RPM through a 3.4286:1 speed ratio gearbox, we maximize the pump’s head, allowing the slurry to maintain high velocity even at the 3km mark.

Q2: What is the fuel efficiency of such a large power system?

A: The DK550 Cutter Suction Dredger Ship is surprisingly economical. The Weichai 12WH17C engine features a minimum fuel consumption of only 188g/KW/H. In a 24-hour operation, this precision injection technology can save significantly more fuel than older mechanical engines, directly boosting your project’s ROI.

Q3: Can we operate the DK550 with a limited crew?

A: Yes. The DK550 Cutter Suction Dredger Ship features a centralized one-man control system in the cabin. All hydraulic functions—from the cutter head and winches to the optional anchor boom and carriage systems—are integrated into an ergonomic console. This allows a single skilled operator to manage the entire dredging cycle.

Q4: Is the DK550 suitable for rocky or high-abrasion mining environments?

A: Absolutely. We use High-Chrome Alloy for all wear-prone parts of the slurry pump and 5-blade alloy steel for the cutter head. Additionally, we provide a "Wear-Part Package" specifically for mining projects to ensure your downtime is kept to a minimum.
