Water pump

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.

Pump remote

enable diver to remotely set pump throttle at full or idle position enable diver to remotely control water pump throttle

Airlift

Diver operated airlift dredge Lightweight, airlift dredge,capable of high excavation rate in most demanding sediments. Ease of transport and quick setup makes it ideal for interventions and small to medium scale jobs. Removal capacity up to 70+m³ (91 yd³) / hour* All models: Multiple, high-performance air injection nozzles (0,99 discharge coefficient) Highly efficient in shallow water (2-3 m / 6-10 ft) Waterjet addon /remote water pump control - optional. *dependent on dredge handling and sediment type, based on 10% solids

Airlift anchor

Weight: 40 kg / 88 lbs inflatable to neutral buoyancy for easy re position by diver Use air from dredge air supply

Dredge systems

Water dredge system

WDS 1 / WDS 2 Diver / ROV operated water dredge systems Heavy-duty, high capacity water dredge. Removal capacity up to 110 m³ (144 yd³) / hour* Diver, remotely operated water pump throttle and backflush - optional on both models. Hydraulically powered water pump and fixed, water nozzles (0,98 discharge coefficient). WDS 2 dredge is fitted with a waterjet water pump. *dependent on dredge handling and sediment type, based on 10% solids

WDS c Diver operated water dredge system Heavy-duty, high capacity water dredge. Removal capacity up to 110+ m³ (144+yd³)/ hour* Diver, remotely operated water pump throttle and backflush - optional. Interchangeable water nozzles(0,98 discharge coefficient) and interchangeable water pump,enable the user to fully customize dredge performance - optional. WDS c can be powered by surface water pump Waterjet attachment - optional. *dependent on dredge handling and sediment type, based on 10% solids

Swivel intake

easier and faster dredging

Airlift dredge system

ADS 1 / ADS 2 Diver operated airlift dredge systems Heavy-duty, high capacity airlift dredge. Removal capacity up to 140+ m³ (183+yd³) / hour* All models: Multiple high-performance air nozzles (0,99 discharge coefficient) Improved efficiency in shallow water (2-3 m / 6-10 ft) Diver remote operated air supply valve- standard Automatic safety air shut off valve- optional. Waterjet with remote water pump control- optional. *dependent on dredge handling and sediment type, based on 10% solids ADS 1 enables dredging up to 50 m (164 ft)water depth ADS 2 enables dredging in shallow water 0,5 m (2 ft) Both models enable dredging under overhead obstacles Safety air shut off system prevents accidental airlift refloating, if a diver does not manually shut off the air supply when a blockage occurs.

Swivel intake easier and faster dredging

Airlift anchor Weight: 60 / 100 /150 kg // 132 / 220 / 330 lbs -optional inflatable to neutral buoyancy for easy re position by diver Use air from dredge air supply

Airlift dredge module

Air chamber and waterjet modules are designed to enable the user to quickly assemble highly efficient airlift using standard tubing and flanges. Suitable for crane suspended airlift dredges. Sturdy construction to withstand rigors of the job.

Airlift air chamber

ACh The heavy-duty air injection chamber increases airlift dredge excavation capacity.

Waterjet WJ Heavy-duty waterjet,significantly increase dredging speed. Interchangeable nozzles enable: A wide range of water pumps to be used. Pressure/flow adjustment for jetting in different sediments. Adjustable jetting pattern

LP waterjet

Waterjet add on Diver operated waterjet Heavy-duty, high capacity waterjet. Suitable for quick fluidization and blowing off large amounts of different sediments. Powerful enough to push of 50+ kg (110+ lb) stones (when used with 40+ hp water pumps) Comes with: four sets of interchangeable nozzles to set adequate pressure/flow required for jetting in different sediments using different water pumps. annular air injection add on - optional performance chart for quick nozzle selection.

Significantly increase dredging speed in all sediment types. Interchangeable nozzles enable: A wide range of water pumps to be used. Pressure/flow adjustment for jetting in different sediments. Adjustable jetting pattern
