DOP SUBMERSIBLE DREDGE PUMPS

DAMEN DREDGING EQUIPMENT

THE DOP SUBMERS IBLE DREDGE PUMP, A MULT IFUNC TIONAL DREDGING TOOL

Damen offers a complete range of heavy-duty submersible dredge pumps. These compact DOP pumps are directly powered by either a hydraulic or an electric motor, mounted in a protective casing.

A highly efficient, wear-resistant dredge pump with a large spherical passage is at the heart of the DOP pump. It has excellent suction properties and reaches extremely high mixture densities. The DOP pump has been designed for highly abrasive dredging environments.

■ Efficient transport of sand / water mixture

■ Wear resistant pump parts fit for an abrasive environment

■ Compact and robust design■ Easily exchangeable suction heads■ Large sphere passage in impeller■ Maintenance friendly mechanical

shaft seal – grease or gland water not required

■ High mixture density due to submersed use

■ Unlimited operating depth■ User-friendly ‘plug & play’ design■ Complete dredge package delivery

including auxiliaries available

T H E D O P P U M P D E S I G N

DOP pumps are designed to be user friendly and easy to maintain. For instance, a cartridge-type mechanical shaft seal that does not require grease or gland water is fitted. Inspections of the impeller can be made simply by using the inspection hatch, which is integrated into the suction pipe.

THE H Y DR AUL IC ALLY DR I V EN DOP SUBMERS IBLE DREDGE PUMP

The hydraulically driven DOP pump has been designed to efficiently dredge a sand/water mixture. It has been fitted out with its own built-in motor, which can be driven by either the excavator’s power unit, or by a separate diesel-hydraulic power pack.

On the lower casing, different types of suction heads can be flange-mounted. This easily interchangeable system ensures the fast mobilisation of the DOP submersible dredge pump and makes it fit for any dredging job.

■ Hydraulic motor directly drives the dredge pump

■ Robust casing protects hydraulic drive

■ Fast mobilisation as hydraulic quick couplings are used

■ DOP can run on excavator’s hydraulic power pack

■ Proven design: for the past 25 years, DOP pumps have been in use all over the world

■ Hydraulically driven cutter unit and auger available

THE ELEC TR IC ALLY DR I V EN DOP SUBMERS IBLE DREDGE PUMP

The Damen DOP pump is also available with an electrical drive. The compact permanent magnet motor directly drives the pump shaft. The clean and silent technology is especially fit for environmentally sensitive or residential areas.

The DOP has been designed for efficient sand/water transport. Its electric or hydraulic drive are exchangeable so that the DOP can do its job on any site.

■ The silence of the e-drive enables full scale dredging activities in residential areas

■ The clean operation due to zero waste gas emission of the e-drive

■ High efficiency of the e-drive – up to 90%

■ Compact Permanent Magnet e-drive minimises submersed dredge pump size

■ Low maintenance due to few moving parts

■ Swift connection to generator■ Dedicated frequency converter
