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 ...

No question that many gold prospectors would love to own a dredge, and dredges are very cool pieces of prospecting equipment that will allow you to mine some very nice gold nuggets, but the prices for new ones are really high.Don't forget however, that in the earliest days of dredging, there were no manufacturers, and all small suction dredges were handcrafted units made in someone's garage.

The Venturi Principle. A venturi creates a constriction within a pipe (classically an hourglass shape) that varies the flow characteristics of a fluid (either liquid or gas) travelling through the tube. As the fluid velocity in the throat is increased there is a consequential drop in pressure. Italian scientist Giovanni B Venturi (1746-1822 ...

Suction jet assist makes the equivalent of an extra 10 or 15 inches of effective vacuum available at the dredge pump inlet. Effective vacuum is the total amount of vacuum that can be utilized to raise solids up to the pump inlet port. More is better. Consider for example, a dredge that is maintaining 20 to 22 inches of vacuum without a jet ...

Post by RKC onNov 24, 2012 at 3:40pm. 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. I'm far from convinced that an infinity jet would be any more ...

Dredging is the excavation of material from a water environment. Possible reasons for dredging include improving existing water features; reshaping land and water features to alter drainage, navigability, and commercial use; constructing dams, dikes, and other controls for streams and shorelines; and recovering valuable mineral deposits or marine life having commercial value.

The power jet also allows deeper dredging because the power jet will lift material higher than a suction nozzle can push it. The disadvantage of the power jet is that the power jet and supply hose must be kept under water at all times. Therefore they do not work very well when working in shallow water. The advantage of the suction nozzle system ...

A suction nozzle is the traditional method for creating the venturi. The advantage of using this method is that it can be operated in water as shallow as the dredge will float in. The down side is you need two hoses, one from the pump and the other being the main suction hose gravel goes up. Having two hoses can be cumbersome. Power Jet Gold Dredge

I used the basic straight jet venturi as the baseline and compared it to the tri-jet, the suction nozzle and the infinity jet. The infinity jet produced the most vacuum, the tri-jet was 2nd, & the suction nozzle was 3rd, the straight jet came in last in performance. There are some strange dynamics going on inside the various jets.
