Jun 01, 2015· G''day weary1, My guess would be that there will be an increase in efficiency by replacing a suction nozzle with an infinity jet, if only because a jet will be sucking up the suction hose, rather than the pushing that occurs with a suction nozzle.

Suction nozzles are suction creating devices on a gold dredge. They in effect push material through the suction hose to the sluice box. Suction tips are used in conjunction with power jets, the other type of a suction creating device used on a floating dredge.
Rated at 94 psi and 8120 gph this pump can actually power a 4″ dredge nozzle. You can also run at idle and use for highbanking. The only WARNING is that these pumps need to have a FINE SCREEN over the intake. They do not like sand and gravels. We have run ″ to 4″ dredge nozzles .
The real key to making this design work, is the entire dredge is flooded with water and material, with almost no air bubbles and zero riffles. By the time the gold travels from the Suction Nozzle to the Nugget Trap, the gold has settled to the bottom of the tube.
In any dredge, you will have 2 types of suction devices; either a suction nozzle or a power jet. A suction nozzle only works with higher pressure pumps. The recommendation is a minimum of 140foot head lift for a suction nozzle. A power jet can run at a slightly lower head lift at a 130 foot, however it does require higher volumes.

A Common Suction Gold Dredge Design. A 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.
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.

Dec 10, 2014· You can also use the jet tube instead of a suction nozzle, it would attach straight into the top of your sluice or into your hopper and then you will only have one hose to deal with in the water, but the nozzle end of your hose should be kept under water at all times when dredging or you will get a blast of air and water into your sluicebox and ...

Dredge Nozzles If you''re wondering how a gold dredge can literally suck up gravel from the bottom of a stream without the gravel going through the pump and destroying it, it is because of a handy device called a suction nozzle or power jet nozzle.
In the Suction Nozzle the Jet is exactly centered in line with the final flow of water, where as in the Log design the water flow is at a tangential angle to the water and material flow. In the final analysis, % more power is achieved and this is nothing to sneeze at.

First you have to decide if you want a suction nozzle or power jet type. The suction nozzle puts the highpressure water in right at the nozzle. 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 ...
