Main Features

Exchangeable cutter teeth

cutter dredger with exchangeable teeth

Cutter teeth are fixed to the cutter head through a bolt connection. Therefore, they can be easily interchanged between three different types depending on the material to be dredged, or replaced when worn out.

Tiltable spuds

Cutter Suction Dredger 250 Tiltable Spuds

The dredger has spuds, which can be manually tilted and secured to the deck. This design ensures easy dredge storage & mobilisation, and is convenient for transport in water and by road on a flat-bed truck.

Submersible dredge pump

Cutter Suction Dredger 300 submersible pump

CSD 250 achieves high production rates due to its hydraulically driven submersible dredge pump, which has a higher pumping flow of higher density mixture compared to a pump mounted in the pontoons.

Hydraulic Propulsion

Auger 200 Propellers

Cutter Suction ECO 250 features hydraulic thrusters mounted on the back of the pontoons. This allows for easy maneuverability around the dredging area with no supporting boats & additional costs.

Extendable depth

Cutter Suction Dredger 250

Cutter suction dredger ECO 250 features a maximum dredging depth of 6m , which can be extended to 12m through an additional adapter placed in between the dredge pump and the cutter head system.

Shallow draft

Cutter Suction Dredger Shallow Draught

CSD 250 is designed with three pontoons- one in the center and one on each side. The pontoons provide a floating capacity, which achieves a draft of 0.75m. This allows the dredger to operate in shallow waters.

CSD ECO 250 applications

Mine tailing removal & dredging

Dredge Yard mine tailing removal dredging landscape

Mine tailings are leftover products of raw material mining operations, which are often stored in tailings ponds. Tailings can contain chemicals or valuable materials. CSD ECO 250 is a compact & efficient tool to dredge & clean up mine tailings ponds, for both- further tailings processing or disposal.

River, canal and channel dredging

channel dredging landscape

Rivers accumulate sand, silt and debris, which must be removed to keep waterways open for navigation. CSD 250 is an efficient dredger in all conditions, including strong river currents. Additionally, it can be customized (e.g. increasing swing length, depth, booster stations) for your project.

Reservoir, lake and dam dredging

Reservoir, lake & dam dredging landscape

Accumulated silt & debris clog up reservoirs, which limits water resources. Cutter Suction ECO 250 is ideal for dam dredging, as it is one-truck transportable, easy to mobilize & launch on site. Additionally, it can reach max. depth of 6m (extendable to 12m) & is self-propelled, making it easy to operate.
