Damen DOP Pumps
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 equipment required for a DOP dredge job is usually quite straightforward. The DOP sub pump is attached to the boom of an excavator or hung in a crane.
The challenge in a dredge job is to maximise the dredge pump’s mixture concentration. A higher concentration will result in improved dredging efficiency.
The dredge pump range and the series of exchangeable heads provide a wide range of mixture production - there is always one that perfectly fits your job.

The DOP150 is the most compact slurry pump of the Damen sub pump range. It has excellent suction properties due to its submersed position, and the wide spherical passage in the impeller ensures minimal blockage, substantially boosting its uptime. The DOP150 is a small yet sturdy submersible dredge pump, easy to handle in confined spaces.

The DOP200 is a wear-resistant sub pump fit for excavator mounting due to its limited size and weight. The heavy-duty design maximises uptime in the rough dredging environment. Additionally, the large array of easy exchangeable suction heads ensures that the submersible dredge pump can be used in a wide array of civil engineering and mining jobs.

The DOP250 is a submersible dredge pump directly driven by a hydraulic motor. The dredge pump and drive are mounted in a robust protective steel casing and can be powered by the hydraulics of the excavator, or by a separate power pack. The top of the casing ensures practical mounting to the excavator’s boom, while the bottom rim is fitted out with a flange for an easy exchange of the various suction heads. These include a sand mining head, a barge unloader, cutter unit and an auger unit.

The DOP350L is a compact low-pressure submersible dredge pump. Its user-friendly ‘plug & play’ design results in fast mobilisation. Moreover, it is designed with a maximised ball passage, ensuring optimal uptime as debris is less likely to get clogged in the pump. The dredge pump wear parts are fit for the abrasive dredging environment, making the DOP pump ideal for the efficient transport of a sand/water mixture.

The DOP350 has been designed to efficiently dredge a sand/water mixture. It is fitted out with its own built-in hydraulic motor, which can be powered by an excavator or by a separate diesel-hydraulic power pack. Different types of suction heads can be easily exchanged as they are flange mounted on the lower casing rim. The sludge pump’s practical design ensures a fast mobilisation.

As the largest of the submersible dredge pump series, the DOP450L boasts an impressive mixture capacity of some 4,000 m³/h. The high efficiency dredge pump has been designed for harsh sand mining and a dredging environment where easily replaceable wear parts and a no-flush mechanical shaft seal are required.
