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.
" Dredge. This machine was a trend setter when it first came on the market and it continues to be one of our best sellers many years later. When other " dredges were floating on innertubes, required a suction nozzle for producing dredge vacuum, and had limited depth capabilities, the Proline " dredge sat on sturdy pontoons and used a power jet for dredge vacuum.
The main target of this research is to design an economically andenvironmentally feasible alternative system, to dredge sandy/muddy soil in navigable channels, by a fluidization system and a jet pump. A theoretical formula had been derived to predict jet pump performance under various working conditions using basic fluid mechanics

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 ...

Apr 20, 2017· A friend gave me this little backpack dredge. It came with a nifty little "Couple Jet" nozzle made by Gold Divers, Inc., formerly of Mound House, NV, but now out of business and retired. The dredge didn't come with an engine or pump and I'm trying to figure out what would be the best pump/engine to get for it.

Jun 18, 2016· I will be purchasing a 2 inch suction nozzle or power jet soon but I need some input from some people that have actually dredged. What are the pros and cons of each set up. I will be using the nozzle/jet on my high banker. The high banker is 9in wide …
The suction nozzle puts the high-pressure water in right at the nozzle. 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 ...
K 1 is largely influenced by the pump suction nozzle approaching the impeller eye. To confirm values of K 1, a pump was modified by installing area reducing steel plates in the suction approach as shown in Figures 8-13, 8-14, 8-15, and 8-16.The plates were first formed in wood conforming to existing suction nozzle core box shape, then manufactured in steel and welded in place.
Dredge Jet Nozzles design. DREDGE SUCTION NOZZLES. DREDGE SUCTION NOZZLES By: Dale Russell Suction nozzles can easily be home made, with some ingenuity a few tools.

Jun 13, 2018· A common suction gold dredge design - 4" surface dredge with air compressor. In normal operation a gold dredge is run by an operator at the intake nozzle who directs the nozzle and who captures and discards oversized rocks that would plug the intake hose.
Nov 15, 2008· What I really wanted to know was, do Keene and Proline build a reducer into to the inlet pipe in a suction noozle or is it say 2 inch the whole way round the 180 degree bend, and would a nozzle jet be built the same way as a suction nozzle, ie a reducer built into the inlet.

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 ...
Mismatch Nozzle/Jet: It is critical to have the proper jet or suction nozzle design to optimize suction. So many customers attempt to build there own dredge, and they have no concepts of orifices in the jets and the nozzle. The orifice in a jet should be designed to match the performance of the pump. Each pump has a sweet spot a
I had constructed an infinity jet of my own design and I wanted to explore all the advantages and any problems. The design had an adjustable gap. Since this was a 4.0" dredge with a venturi jet generator, I based the jet opening to be the same square inch area of a 1.0" jet that was used on the straight jet. The area of the 1.0" jet was 0.785 sq.".
To the other end of the jet attach the remaining fitting and pipe nipples. The number of fittings may vary depending on the size of nozzle and pump used. These specifications also enclosed. Suction nozzle: Welding notes: install the first elbow onto the jet prior to welding and insure that the longest point is on top toward the same
