The Dino6 sediment removal system is comprised of a small dredge manufactured domestically. The Dino6 measures just over 22′ long and 6′ wide and is less than 6′ tall. With a wet weight around 4,000 pounds, it is a very lightweight portable dredge, with a low cost of mobilization, and a small environmental footprint.

An airlift is a type of small suction dredge handheld underwater by DIVERS. It works by blowing air into the pipe, and that air, being lighter than water, rises inside the pipe, dragging water with it. The mixture rises and creates a differential pressure that lift water, or semisolid material, up the pipe.

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 piece of typical dredging equipment is shown in Figure 1).

We have the right equipment at the right price for you! From the lightest, most portable back-pack dredge to a fullly equipped 8 inch production system, our experts can analyze your project and your needs to get you set up with the perfect package. Take a look at the wide range of world-class dredges we offer:

Removal capacity up to 70+ m³ (91 yd³) / hour * All models: Multiple, high-performance air injection nozzles (0,99 discharge coefficient)

The Dredge is an efficient alternative to using an excavator, which is expensive, has limited reach, may be destructive to the shore, and typically deposits the material adjacent to the shore, only to wash back in with the first good rain. It also works well as a fire pump. We also have a special model designed for gold prospecting.
