Denialink - Dredge pumps

Damen Dredging Equipment manufactures a large range of dredge pumps, for example:
Inboard dredge pumps
Submersed dredge pumps
Low pressure dredge pumps
Medium pressure dredge pumps
High pressure dredge pumps
Hopper pumps
Booster station pumps
DOP« submersible dredge pumps
Single walled dredge pumps
Double walled dredge pumps

Inboard dredge pumps
Inboard pumps are mounted on board of trailing suction hopper dredgers, cutter suction dredgers, sand win dredgers and in booster stations.
These centrifugal pumps are usually either diesel driven or electrically driven.
Our product range includes low pressure, medium pressure and high pressure dredge pumps which means that we can offer you the right dredge pump for your working conditions : from hopper filling to discharging over kilometres, from pumping gravel to pumping silt.
The dredge pumps can be of the single walled or double walled type.
A double walled dredge pump has a welded mild steel heavy outer casing, which is mounted around a inner pump casing which is a foundry piece.

Submersed dredge pumps
Submersed dredge pumps can be mounted in trailing pipes, on ladders of cutter dredgers or sand win dredgers, or a DOP«-submersible dredge pump can be lowered by a steel cable to the right working depth, or the DOP« can be attached to the boom of an excavator.
The DOP«-submersible dredge pump is usually hydraulically driven.
All submersed dredge pumps can be either hydraulically or electrically driven. Submersed pumps are used when the dredging depth is significant, or to maximise the mixture concentration.

Shaft seals
Various types of shaft seals are available:
Grease packing : a simple construction using grease packing
   which is wrapped around the shaft sleeve.
   The packing is grease lubricated, and gland water is used to
   keep the shaft seal sand-free;
Floating water chamber: a construction needing little
   maintenance and able to withstand higher pump pressures.
   The sealing is done by oil retaining rings, which run on a
   replaceable shaft sleeve which protects the pump shaft.
   The seal is placed in a double, flexible housing.
   The seal requires grease and gland water;
Mechanical seal : a mechanical shaft sealing with ceramic
   surfaces.
   This long-life seal needs ultra low maintenance.
   Grease and gland water are not required, which make the
   seal an environmental friendly and cost-cutting solution.

Foundry materials
The wearing parts of the dredge pump, being the pump casing, the impeller, the wearing plates and the suction mouth, are items cast from wear-resistant materials.
The different casting materials have been developed in particular to extend the lifetime of a wearing part.
Each casting material has its own specific properties.

Each casting material has its own specific properties.

Manganese steel 30Mn5:


Bainitic Nodulair:


Ni-hard 4:

Mo-hard:

This wear resistant material can be welded, which enables the user for instance hard face welding on the impeller.

This more wear resistant. material is used pumping sand/stone mixtures as it is more impact resistant.

This material is very wear resistant.

This material is highly wear resistant.
