![]() ![]() The nozzle pulls in a mixture of air/water/gravel. Unlike a conventional suction nozzle, this does not need to be underwater. I recommend using a separate engine/pump to run the nozzle. This is a very efficient design & added to a conventional dredge will let you operate like a highbanker. The pressure connection on this is 1.25" the nozzle is 3" inside diameter w/ a 2.5" restriction ring on the intake. We recovered some very nice nuggets w/ this nozzle ! Good Condition & works perfectly Includes only the nozzle as shown. This is the jet that was used on the Salmon River in N. You would install this ahead of a conventional 3" powerjet. It requires a 5 HP or larger dredge pump to operate. This nozzle is designed for highbanking/Dryland dredging. In a good creek power jet, In puddle jumping use the suction nozzle.Vortxrex Highbanking/Dryland Dredging Nozzle. The idea is that if you are using a jet flare and should you pop the hose out of the water and lose prime the pressure jet may blast material out of the box, find the angle in which the jet blows over the sluice should somthing bad like that happen. This may be different than yours, I'm not sure if you have a crashbox or a jet flare. The jet inlet position doesn't matter too much on my dredge as I still use the old crashbox style header. The jet log will get better gas mileage than a suction nozzle and provide better suction should you keep it floating on the pontoons. Figure out what rocks to throw away and not hog the nozzle and you will do well. The nozzle restriction will rob your production, fill with small rocks and reduce the flow over the box, the gravels compact, clear the nozzle, and your boxes scour. Don't put any kind of restriction on the nozzle! It's all bad! Get a snorkel and mask and look what is going up the nozzle.
