Ocean-going dredging requires reliable dredge pump technology and deep-seated expertise. Offshore dredging is a complex and challenging field. Dredges need to extract high-concentration slurries from depths of 10 to 100 m and transport them over a distance of up to 6 km. These pumping systems are equipped to handle materials such as large …Web
up and transported through a pipeline by centrifugal dredge pumps. A suction inlet located beneath the cutter head (known as the suction mouth) is connected by a suction tube directly to one or more centrifugal pumps. The vacuum force at the suction inlet sucks up the loosened material. The CSD will discharge theWeb
The Surface Dredge. As the heading ofthis section implies, surface dredge floats on the surface of the water. The material is pumped to the surface through a suction hose into an efficient sluice box that is capable of …Web
A suction dredge is basically an underwater vacuum cleaner that sucks (hopefully) gold-bearing gravel up and runs it through a sluicebox. In more technical terms, suction is created by a motor-driven centrifugal pump moving high pressure water into a jet system, creating a low pressure area that creates suction at the nozzle via the …Web
Priming the Pump. Before you use your suction hose to vacuum up water and material, get your dredge's pump ready for a day of work. Dredge pumps are designed for aquatic use only, so running air through them can cause them to overheat. Lower your dredge pump's foot valve below the water's surface and give it a few back …Web
