Therefore they do not work very well when working in shallow water. The disadvantage of the power jet is that the power jet and supply hose must be kept under water at all times. The power jet also allows deeper dredging because the power jet will lift material higher than a suction nozzle can push it. The advantage of the power jet is that the operator of the dredge has to only deal with one hose when he is dredging. The answer is that they each have advantages and disadvantages. Which system is better - a power jet or a suction nozzle? A vacuum is created which sucks up water and gravel, but the material is pushed through the hose instead of being sucked through the hose, as in the case of the power jet. Hoses, clamps, and other dredge accessories are not included.Ī suction nozzle works in a similar fashion to a power jet except instead of being attached directly to the header box it is attached at the far end of the material hose. Other sizes of suction nozzles are available from the drop down menu.
Also makes sure your pump engine has enough power to move that size material at your preferred depth. When ordering a nozzle make sure the inlet diameter matches your pump fitting size. A 2 inch pressure hose is easily secured to the nozzle with a 2 inch threaded coupling. #ke-sn2515 outlet size: 2.5" inlet size: 1.5"Įxample: A ke-sn32 dredge nozzle (measures 3" x 2") - the suction nozzle outlet measures 3 inches and will work with our 3 inch suction hose. #kesn2 outlet size: 2.0" inlet size: 1.25" Prices start at $135 for a 1.5" Suction Nozzle. Ideal for shallow water dredging - these dredge suction nozzles are precision manufactured by Jobe and Keene from thin-wall plated steel tubing with machined orifices to create maximum suction pressure.
