Product Description


Dredge pumps are a special category of heavy-duty slurry pumps that are utilized in the process of dredging. Dredging is referred to as the process of transport of underwater sediments (usually sand, gravel or rocks) from one region to another.
A dredge pump is a horizontal centrifugal pump and is the heartbeat of a dredge. It is designed to handle abrasive granular materials and solids of limited size in suspension. Without the dredge pump, a cutter suction dredge would not be able to transport slurry.

1.How does a dredge pump work?

The dredge pump contains a pump casing and an impeller. The impeller is located inside the pump casing and is attached to the drive motor via gearbox and shaft. The frontal portion of the pump casing is sealed with a suction cover, connecting directly to the dredge’s suction pipe.  The dredge pump’s discharge is positioned near the top of the dredge pump and is connected to a separate discharge line.

3.How to select a suitable dredge pump?
Most standard dredgers are designed and outfitted with an dredge pump to achieve an overall productivity range in cases where the pump size and type are undefined, it is worth considering the following factors when selecting a dredge pump: type and thickness of material to be pumped, whether diesel or electric power is required, engine HP (kw) needed, pump performance data, durability, ease of maintenance, and  average life expectancy under normal operating conditions, all vital attributes in the selection process. Of equal importance is matching the appropriate pipeline size and composition to maintain proper flow of material without clogging the pipeline and to maintain required pumping production to complete the job.
