Water dredge
Diver operated water dredge
Lightweight, water dredge, capable of high excavation rate in most demanding sediments.
Ease of transport and quick setup makes it ideal for interventions and small scale jobs.
Removal capacity up to 40 m³ (52 yd³) / hour*
All models:
Interchangeable, high-performance water nozzle
(0,998 discharge coefficient).
Interchangeable water nozzle provides the best overall dredge performance when different water pumps are used.
Optional:
Diver operated water pump throttle control.
Waterjet add on.
* dependent on dredge handling and sediment type,
based on 10% solids

Water pump
Water pumps
Pump throttle remotely, diver operated
(these are not trash pumps)
To power the WD range of dredges we selected water pumps with the best power efficiency available on the market.
Power range from 3,5 to 11,7 hp to facilitate different dredge diameter and job requirements.
All water pumps are fitted with remote, diver operated pump throttle control, and large capacity fuel tank (10 hours operation @ full throttle).
There is no need for an assistant to control and refuel the water pump.
Other water pumps at request.
If you want to use your pump we will customize a water nozzle for best system performance.
As an option, we can supply pump float. It can support a pump and one person. Pump float save deck space eliminates vibration and reduce noise on-board vessel. It enables several pumps to be deployed from a small boat. Floats are easily pulled and repositioned by the diver. If dredging is at safe distance from the shoreline, pump float eliminates the need for boat assistance.
