Doro Pump with feeding screw
The Doro pump is a hydraulically operated dredge pump with a screw feeder that breaks off and feeds sediment into the pump intake. The Doro pump is easy to attach and changing to another tool takes only a few minutes. The Doro pump is delivered ready for assembly on the lifting arm.
The Doro pump can be delivered with the following accessories: hydraulically operated telescopic extension to increase the dredging depth and facilitate maneuvering.
Doro pump standard kit:
1 hydraulically operated feeding screw, 6 m spiral tubing incl. couplings, 25 m flat tubing Ø 105 mm with camlock quick coupling with buoyancy tube.
10 floaters, 5 m flat tubing with quick coupling and end nozzle, 1 suction nozzle, 1 X4 attachment 0.9 m, 1 extension 0.7 m, 1 bracket set for dredging hose.

The Doro pump is supplied with a standard kit.
Standard set weight: 86 kg
Max. capacity: 130 m3/hour
Max capacity with lifting height:
1 metre 120 m3/hour
