![]() ![]() The 3D printed reduction/injection insert piece has a final reduction of 1/4' from 3/4' supply. ![]() I figure the pump will produce about 10 - 12 psi. ![]() In a good creek power jet, In puddle jumping use the suction nozzle. This is my 1 1/4' venturi suction nozzle for my electric micro dredge powered by a 24v 3700gph bilge pump. 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. The other drawback of a 2 or a 2.5 is that these usually are not equipped with air.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. Includes 15 feet of suction hose and 17 feet of pressure hose. The suction nozzle is ideal for working in shallow conditions. So if a 2" will move 2 yards per day then a 3" will move 4 yards.Ī 4" dredge is a good balance between large capacity and compact size and can be moved and operated by one dude. The Model 2004 is constructed with an aluminum frame and is supported with grey hard cross-linked polyethylene pontoons. Rule of thumb on size difference is: with every inch of nozzle size you increase, you double your production capacity. It took us a full week to dig a 10 yard hole with the 3". My first real dredge was a 3" and that damn thing nearly worked me to death because if the rock wont fit up the hose, you have to move it by hand. When people first get into this they tend to start small but ALWAYS move up to larger gear. Buy the biggest dredge you can afford that is small enough for you to handle and legal in your area. A lot of people ask me this question and my answer is the same. There wont be much difference and your first dredge should not be a new one unless you have plenty of disposable income. ![]()
