Power Jet Gold Dredge. A Power Jet is more efficient because there is a shorter pressure hose from the pump and therefore less friction losses. The Power Jet enters the suction line just before the sluice, which means the gravel is being "pulled" up the hose rather than "pushed" by a suction nozzle. This can help prevent blockages.

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 venturi effect.

The DAE Pumps pontoon dredge pump performs ideally as a small sand dredge. With the heavy-duty submersible slurry pump that is capable of suctioning sand, silt, sediment, and slurry, the pontoon dredge pump skims across the bottom, pumping material, sand, and debris. The angled bars allow the pontoon dredge pump to move freely as heights increase and decrease.

Hello fellow prospectors. I have an idea about making a gravity dredge to try out on one of the rivers here. I already have 14 feet of 2 inch hose. My main question is that if I add 40 feet of 4 inch hose to the end of the 2 inch, will that help to increase the flow and suction of the nozzle for the 2inch hose? Or should I just add more 2 inch hose to the 14 feet I have now?

What I like about this approach is that to achieve good syphon suction in a gravity dredge usually means that you need 4-6ft of drop which may require 100ft or more of hose length in the area your working which corresponds to high costs of suction hose and dealing with jams etc.. If the gravity assist jet works you could run cheaper hose/pipe ...
