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.
Jun 18, 2016· Yes, certainly in a dredge - but even a highbanker as well. An uncontrolled blasting of water, air and slurry into any system (air in the power jet) is never a good thing. When you loose control of the % of water and slurry going into the 'banker', and .

Jul 17, 2010· Why is the power jet not suggested for shallow water? When you pull the nozzle out of the water it will send a blast of air/water through the hose and when it hits the sluice it will blow most all of the material including gold out from behind your riffles and out of the sluice :whaaaa:, don't try it you will not like the results especially if ...
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.

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.
These are 1) The suction nozzle where the jet is up at the nozzle point, and 2) The power jet where the jet is located up near the sluice box. In addition to pumping water, the small engine also produces compressed air for the diver to use while underwater. ... Summer and fall are usually the best times of the year to dredge for gold because ...
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.
Apr 16, 2014· I have the basic design figured out, can anyone give me the ratio of the size of thewater inlet line to the suction line size? Also pressure/gpm needed to be effective?Ive got a 40 drop and going from 3 to 1 1/2 line size to run my Simple Simon.Im hoping to run a 2 suction nozzle/power jet. :hmmm...
A power jet puts the high-pressure 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.
A dredge designed to work on flotation, with a compressor for underwater dredging, is almost always equipped as a power jet. Since a power jet and supply hose must be kept under water at all times, it won't work very well in shallow water. Shown below is a wide variety of gold dredge nozzles from several reputable manufacturers.

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.
The result is a lighter power jet with better vacuum and easier priming. These power jets are popular with those building their own dredges or who simply wish to improve performance on dredges they already own. 1.5" Power Jet ($133) 2" Power Jet ($146) 2.5" Power Jet ($157) 3" Power Jet ($207) 4" Power Jet ($266) 5" Power Jet ($335) 5" Twin-Jet ...

In the case of the power jet, for 100 GPM applied to the venturi jet, it only sucked 50 GPM through the nozzle and dredge-hose. I repeated the test 5 or 6 times and the results were always the same. The suction nozzle drew 75 GPM and the tri-jet drew 90 GPM. I expected an efficiency of 100 GPM applied to the jet and sucking 200 GPM, with a ...
