Hydraulically driven submersible dredge pumps

The small dredge pump that realises big things

Hydraulically driven submersible dredge pumps

COMPACT YET POWERFUL

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.

EXCHANGEABLE SUCTION HEADS

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.

HOW DOES DOP DREDGING WORK?

The DOP dredge package

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. As the DOP pump is a hydraulic dredge pump it will run on either the hydraulics of the excavator, or on an additional power pack. The complete unit can be placed on a quay or pontoon, whatever the job demands. Additionally, flexible hoses or piping are required for the mixture discharge.


THE DREDGING PROCESS

Advantages of a submersed pump

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 submersed DOP ensures that the concentration is maximised: it is located as close as possible to the sediment to be removed. Moreover, the static head improves the pump output. Additionally, a jet water assisted mining head or a cutter head will both loosen the bottom material, making it much easier to pump up. All these elements combine to optimise dredge production.

STANDARD DREDGE PUMPS

Customised for any job

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. Moreover, the interchangeable suction heads have been designed to cover just about any project in suction dredging. As these small dredge pumps are for sale from stock, the lead times are nice and short.


WHAT DREDGE PRODUCTION DO YOU REQUIRE?

Impressive results from a small dredge pump

How much dredged material does your classification plant require? Or are you looking for a precision dredging suction pump? These extremes meet in the small dredge pump named DOP. The Damen DOP pump maybe a small piece of dredging equipment but you will certainly be impressed by how much output it produces!

A DOP dredge package has been delivered to Qatar. The delivery includes a hydraulically driven DOP150 including hydraulic hoses, mixture hoses and hoisting gear.

DOP200 with sand mining head (2 sets)

Two sets op DOP dredge pumps have been delivered to HALEX Construction in Singapore. The sand mining pumps will be used to disperse previously mined sand over the relatively unstable clay bottom of a newly created polder in Singapore.

DOP250 with cutter head

A DOP dredge pump, type DOP250, including cutter head and dredging instrumentation has been delivered to Australian contractor Polaris Marine Pty through the Damen Service hub in Brisbane.

DOP150 with sand mining head

A DOP150 has been delivered with spares and auxiliaries to Dredging Africa, to assist a mining operation. As the dredge pump was on stock, the dredge package has been delivered within a week.

DOP200 with power pack

A DOP dredge pump and matching power pack have been delivered to the Swedish contractor Peab AB. The dredge package delivered included mixture discharge hoses, hydraulic hoses for the dredge pump drive, as well as a set of spares.

DOP150 with cutter head

A DOP150 has been delivered with standard sand mining head, plus a cutter head and top plate for mounting on an excavator’s boom. The submersible sand pump will work in Asia.

DOP250 with cutter unit

A complete DOP dredge package has been delivered, including a diesel-hydraulic power pack for driving the DOP dredge pump and its cutter unit, plus a jet pack supplying the sand mining head with pressurised water.

DOP250 with sand mining head

A DOP250 dredge pump has been delivered to Angola. It will work, attached to a wire crane, together with another DOP on a local harbour project. The DOP will remove silt to medium fine sand recently deposited along the various quays.

MAKE YOUR NEXT JOB A DOP JOB

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.

Package delivery

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.
