In any dredge, you will have types of suction devices; either a suction nozzle or a power jet. suction nozzle only works with higher pressure pumps. the recommendation is a minimum of 140-foot head lift for a suction nozzle. power jet can run at a slightly lower head lift at a 130 foot, however it does require higher volumes.
dec 10, 2014 hello guys, once you give me plans to make suction nozzle, but when my profile was deleted for safety reasons all posts its gone. can you again give me plans how to build it pls? hope to start these days to make my eqwipment. and plans for making highbanker combo its also be usefull to me. thinks to make something like this
buy a "gold dredge suction nozzle". and smaller is about sd. Or do a web search for the same to see what they look like. forget about the proportional mixer type venturis ala carburetor type. the curved section is the high pressure line coming from the pump. 34" garden hose will run a nozzle as long as you have pressure, the more the
jun 14, 2013 suction nozzles and power jets are, without a doubt, the most problematic dredge parts for a home build dredger to construct. most dredge builders would be far better off to buy a power jet or nozzle from an established dredge manufacturer. cant add any more about building a nozzle or power jet than what has been previously written in this

jun 01, 2015 Im new here and wanted to join so could ask questions. Im new to dredging also. like to tinker and like to build my own stuff. and currently want to make the jump from using suction nozzles to infinity jets. now ive also built my own dredge, set up currently for fine gold recovery it works ok but theres always room for improvement.
getting back to the jetting systems of dredges: ie, power jets & suction nozzles. these are what create the suction of a dredge venturi system & no material is sucked through the pump itself. imagine the damage to a pump if this were the case. volume of water under pressure is pumped into a steel tube at an angle as shown in the above diagram.
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.

posted in another thread discussing muck removal options but thought would give this a dedicated thread. one suggested diy solution to remove organic muck from an old pond is to build something akin to a gold dredge with a trash pump and a venturi dredge nozzle.
small "lawn mower" type of engine is used to pump water which creates the suction that pulls the sand and gravel up through a hose and into the sluice box. the gravel does not go through the pump, the suction in the hose is actually created through a venturi effect by pumping high pressure water through a
oct 17, 2011 want to build a suction nozzle gold dredge but dont know how to do it. make things by cutting and welding metal tubing and believe the dredge is using a venturi affect to create the suction at the nozzle. have listed some things that think need to know to build this and would appreciate anything else you could add.
nov 15, 2008 its encouraging you have decided on a 4-inch dredge, rather than a 3-inch which would have been mostly useless. and the more think about it, the use of a well designed 4-inch surface dredge in some of the small streams of the lakes district sounds very appealing, and it would be great fun during a hot otago summer.
dec 05, 2012 have now converted the sluice box into a suction dredge My idea is to set it next to a small creek and suck out from underneath the big boulders. have a briggs and stratton 3.5 HP pump which delivers 150 gpm It appears to be supplying more than enough pressure and flow. now to the problem my diy suction nozzle.

In the case of the power jet, for 100 gpm applied to the venturi jet, it only sucked gpm through the nozzle and dredge-hose. repeated the test or times and the results were always the same. the suction nozzle drew gpm and the tri-jet drew gpm. expected an efficiency of 100 gpm applied to the jet and sucking 200 gpm, with a
power jet puts the high-pressure water in just before the sluice box. suction nozzle is best in very shallow water; a power jet produces better overall suction. most dredges are power jets, but some smaller units, inches and smaller are suction nozzles. recommend the power jet. take a close look at the jets made by the manufacturers
