Main features

Integrated system

Integrated dredge pump and drive system (CSD 400 & 450)

CSD 400 features an integrated dredge pump & drive system. In other words, dredge pump is coupled with the gearbox, which is coupled with the engine. This makes the dredger more compact & efficient.

Exchangeable cutter teeth

The dredger’s cutter teeth are fixed to the cutter head through a bolt connection. This design ensures that they can be easily interchanged between three different types depending on the material to be dredged, or replaced when worn out.

Shallow draft

CSD 400 Shallow Draught

Cutter Suction 400 has a shallow draft of 1.1m. This is achieved due to its three pontoon design – one in the center and one on each side. The pontoons provide a floating capacity, which allows the dredger to easily operate in shallow waters.


Cutter Suction 400 (3 pontoons, dismountable)

For practicality and transport reasons, cutter suction dredger 400 is dismountable. More specifically, it can be taken apart into one central pontoon, two side pontoons, a control cabin, the spuds and the cutter ladder.

Transportable by road

CSD 400 transport on a flat rack container by truck

Due to its dismountable design, cutter suction dredger 400 can be easily transported on a flat rack container by truck. This makes the transport process easier and cheaper in comparison to other large vessel transport methods.

River, canal & channel dredging

channel dredging landscape

Regular maintenance dredging is necessary in order to remove accumulated sand, silt and debris & keep waterways open for navigation. CSD 400 is an efficient dredger for bigger maintenance projects. Due to exchangeable cutter teeth and high power, it can operate in a variety of conditions.

Reservoir, lake & dam dredging

Reservoir, lake & dam dredging landscape

CSD 400 is ideal for larger reservoir, dam or lake maintenance & dredging. It is a powerful dredger, which can be adapted to different materials by choosing the right cutter teeth. Additionally, it has a range of customization options depending on the dredging environment & requirements.

Mine tailing removal & dredging
