Various DOP pumps and suction heads available

DOP submersible dredge pump

Compactly built wear resistant submersed dredge pump directly driven by a hydraulic motor.

DOP head

Easily exchangeable suction head available in a wide variety each specific for a different dredging job.

Hoisting

Attachment to crane

Chain spread or welded counter counting plate for flexible or fixed coupling of the DOP unit to the hoisting tool

Crane or A frame for suspension

Hoisting and maneuvering of the DOP unit is arranged by the excavator or by a dedicated pontoon-mounted A-frame including winch.

Power

Hydraulic power pack / excavator to power the DOP submersible dredge pump

The DOP submersible dredge pump is powered by a diesel-hydraulic power pack, built into a protective casing

Hydraulic hoses power pack to DOP submersible dredge pump and vice versa

Hydraulic hoses fitted out with quick couplings on both ends connect the DOP submersible dredge pump to the power pack.

Hydraulic hoses power pack to some suction heads and vice versa

Hydraulic hoses fitted out with quick couplings on both ends connect the cutter head & auger unit to the power pack.

Discharge

Discharge hose

The dredged mixture is transported through flexible rubber hoses of which one end is bolted to the discharge flange of the DOP submersible dredge pump, and the other flange connect to re rest of the piping of which the overall length is determined by the dredging project.

Floats (on discharge hose)

Floats can be clamped to the discharge piping of the DOP submersible dredge pump, whether the piping is flexible, made in HDPE or in steel.

Further discharge piping

From the DOP submersible dredge pump to the spoil field floating and land-based discharge piping is required.

Auxiliaries

Hoses for jetwater supply to some suction heads

Pressurised jetwater is supplied from the jetwater pump to the sand production head and flat bottom head by means of flexible hoses.

Jetwater pump incl drive

A separate jetwater pump complete with diesel drive is installed in an easily transportable unit. The jetwater pump supplies the pressurized jetwater for the suction heads.
