Used deep suction dredgers for sale
Above you will find the deep suction dredgers we currently have for sale. Our listing is an electric driven plain suction dredger built in 2007: 24.00 x 7.00 x 1.20 m, 260 mm pipe diameter, a DOP2320 ladder pump with a capacity of 1,000 m³/h mixture and a 400 kW electric power pack. It dredges up to 30 m deep as a plain suction dredger, or up to 22 m with the 40 kW cutter ladder, and has a DGPS dig system with Hypack and a speed and density meter. Please contact us with the folio number for full specifications.
If you need a different pipe diameter or dredging depth, send us your requirements and we will approach owners directly.
How a deep suction dredger works
The dredger lies on anchors or winch wires above the deposit and lowers a suction pipe or ladder, often with a submerged pump, into the sand or gravel. The material flows towards the suction mouth as the slope of the pit gives way, and the dredge pump sends the mixture through a floating pipeline to the shore or a processing plant. The length of the ladder decides the maximum dredging depth; a submerged pump on the ladder allows deeper dredging than a pump on deck.
Plain suction or cutter suction?
- Plain or deep suction dredger – no cutter, for loose sand and gravel in deep water, with a simple and economical set-up.
- Cutter suction dredger – a rotating cutter head loosens compact soils, clay and soft rock before suction.
- Combined units – some dredgers, such as our 260 mm listing, can work with either a suction head or a cutter ladder.
Long pipelines to the processing plant may need a booster station.
What does a deep suction dredger cost?
There is no list price for a used deep suction dredger. The price depends mainly on:
- Pipe diameter and pump – pump make and type, capacity and installed power.
- Dredging depth – ladder length and whether a submerged pump is fitted.
- Drive – diesel or electric, power pack and running hours.
- Equipment – cutter ladder, winches, positioning and dredging software, floating pipeline.
- Age and condition – year of build, wear of pump, pipes and ladder, and the state of the hull.
- Location – the cost of dismantling, transport and assembly at your site.

Frequently asked questions
How much does a deep suction dredger cost?
That depends on pipe diameter, pump, dredging depth, drive, age and condition. Send us your requirements and we will send you suitable dredgers with full specifications, or ask for a valuation of a specific dredger.
What is the difference between a deep suction dredger and a cutter suction dredger?
A deep suction dredger has no cutter and relies on loose material flowing to the suction mouth, which suits sand and gravel at great depth. A cutter suction dredger loosens the soil with a rotating cutter head, so it can dredge compact soils and clay but usually at a smaller depth.
Can a suction dredger be transported to an inland pit?
Smaller suction dredgers are often dismantled and transported by road, then assembled at the pit. Ask us for the transport dimensions and weights of a specific dredger.
How do I sell my suction dredger?
Send us the main particulars, pump details, dredging depth and recent photos via List your vessel, or contact us directly. We advise on a realistic asking price and present the dredger discreetly to buyers worldwide.
