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 power sluice "washes" material you shovel into it, whereas a dredge sucks material up from a stream through a hose and deposits it into the sluice. #7835 shown above comes with BOTH types of header boxes AND a dredge nozzle and a bigger pump so you can use this one piece of mining equipment as either a sucking dredge or as a power sluice.

A dredge designed to work on flotation, with a compressor for underwater dredging, is almost always equipped as a power jet.

Jun 13, 2018· A gold dredge is powered by a motor and pump. A common misperception is that gravel is sucked through the pump. The pump actually pumps only water, which is delivered to a venturi type device (called a power jet or a suction nozzle) which indirectly creates suction in a larger hose. The solves two problems.

Battery Power Jet for Gold Dredge Test Run Short Version Full Video: Testing my latest project A battery powered mini suction jet for gold dredging. It runs off a 12v bilge pump (any pump doing 800+gph) and is small enough for the creeks, streams, even an irrigation ditch where I''m testing it.
With a suction nozzle, the distance the water for the dredge is under suction is very short (less than a foot) vs a power jet nozzle may have water under suction for 20 ft or more. After the water passes the intersection in the power jet or suction nozzle, you are no longer sucking material.
In the case of the power jet, for 100 GPM applied to the venturi jet, it only sucked 50 GPM through the nozzle and dredse. I repeated the test 5 or 6 times and the results were always the same. The suction nozzle drew 75 GPM and the trijet drew 90 GPM. I expected an efficiency of 100 GPM applied to the jet and sucking 200 GPM, with a ...

A power jet puts the highpressure water in just before the sluice box. A suction nozzle is best in very shallow water; a power jet produces better overall suction. Most dredges are power jets, but some smaller units, 3 inches and smaller are suction nozzles. I recommend the power jet.
