Hydraulically driven submersible dredge pumps
Fit for any dredging job
The DOP submersible dredge pump is a heavy-duty slurry pump designed with a harsh dredging environment in mind. The compact submersed pump is directly powered by a hydraulic motor. The impeller has a large sphere passage and is cast in wear resistant material. This makes the DOP pump fit for any dredging job.
The ‘jack of all trades’
Even though the DOP pump may be the smallest piece of dredging equipment in your fleet, it may well be the most versatile one. The DOP pump unit adapts effortlessly to its next job as it can easily exchange its suction head. These range from a jet water assisted sand mining head, to a cutter unit to break up cohesive soils, and from an auger head for precision dredging to a leveller head for clearing building pits or barges. Therefore the DOP pump is transformed into the perfect tool for your next dredge job.

What type of DOP suits you best?
Let’s discuss the dredging works you need to do and we will offer you the dredge pump which perfectly matches your requirements.
A job well doneMore projects
DOP200 in diving operation
The Belgian specialist diving company SUBMAR BV ordered a DOP200 dredge pump for one specific project: cleaning out the Charles de Gaulle lock in Dunkerque, northern France.
Hydro power dam dredging by DOP350
In the Enguri River, a hydropower dam was built during the 1970s and 1980s. Due to the natural circumstances in the area (North Western Georgia, near Abkhazia) the concrete dam could have vast dimensions.
DOP200 on amphibious excavator
In high winds an amphibious excavator has done a precision dredging job near a Dutch dyke. The project aim was to remove a limited volume of silt – some 4.000 m³.
DOP150 attached to amphibious excavator
Various industrial settling ponds of the AGL Loy Lang power station needed maintenance dredging. To ensure these ponds can be used to store their maximum capacity of ash and fine sand, they are to be cleaned at regular intervals.
Precision sediment removal by DOP150
DOP submersible dredge pumps are not only used for standard harbour maintenance dredging, they can be integrated in intricate industrial pond maintenance as well.
DOP200 used for unloading hopper dredger
In New Zealand, a DOP pump has been used to empty a hopper dredger, and replenish a local beach. The 850 m3 hopper dredger New Era dredged the sand locally.
Precision dredging at prestigious construction project
The Netherlands has substantial infrastructure to protect its low lying lands against high water. A feast of engineering is the “Afsluitdijk”, a 32 km long dyke.
Your partner in dredging
Dredging requires more than just shipping a dredge pump. It requires more gear such as dredge piping and power packs to do the job, and it requires crew training and project management to bring the works to a successful conclusion. Damen can assist you when starting up your project, and we are also there for you during the full lifecycle of your DOP dredge pump.
The DOP submersible dredge pump can be delivered from stock as a single item. Yet, for a swift and practical start-up, we can supply a complete dredging package. This package can include another suction head for the sub pump, hoisting gear to facilitate crane mounting, hydraulic hoses and much more.
While your new DOP dredge pump is being shipped, make use of this time to get prepared. Arrange the excavators’ connection, or check the available power, prepare the hydraulics for the dredge pump drive… This enables you to swiftly start your dredging job upon delivery of DOP pump. Make use of our checklist.
Wear & spare parts deliveries
The DOP dredge pump has been designed to pump abrasive materials; it will pumps tonnes of gravel, sand and other slurries. Consequently, the heavy cast pump parts will be subjected to wear. Seals may need replacement and bearing oil has to be exchanged. All these can be shipped to your jobsite.
