Damen Shipyards, an international shipbuilding group, has just released a video about their DOP Submersible Dredge Pump 200.
The Waterking excavator, as shown in this video, or the excavator available locally, can be turned into an instant dredger by connecting a DOP submersible dredge pump.
The DOP is powered by the hydraulics of the excavator, which results in a simple easy to use system. The DOP submersible dredge pump is fitted out with highly efficient, wear resistant impeller and pump casing which enable a large spherical passage.
A wide array of easily exchangeable suction heads is available. This tailors the DOP for any specific dredging job at hand.
