Keene Engineering shows how we test equipment before it even makes it onto a dredge. There is a lot more involved in building the best equipment in the world than meets the eye.
Awesome work boys but nowhere in the state I live in can you dredge they say it's legal but won't issue permits to do so,they say it kills the fish,,so does fishing
First I'd use a proper sized tub to stop cavitation to get true values instead of a wrong size tub dragging air inside the pump ,use a vacuum dial gauge with different material through it would give a better understanding then seeing how far you can push it up in the air ,the pump efficiency is effected by materials passed through, ie the venturi effect then the push of the materials once past the nozzle
Dean all good comments however I do know better. There was no air in that system. I had the hose bent in a manner that we had no cavitation. You are correct any air would greatly reduce the efficiency of the pump and the venturi system.
@@KeeneEngInc Hey ,I wasn't trying to pull you down ,it's just if you study the effects of a boat prop in a small tank you see how it effects the prop cavitation is greatly raised due to sloshing water trapping air which swirls about the tank ,i think some colleges have put the study up on here in slow motion footage,i read it when studying prop design ,what helical draw work have you done ? Like eddy effects with positioning jetting ,such as 19° merging also 19° crossing flow at higher pressure and lower pressure ,the effect like propulsion without a prop ,sort of like new propless jet drive type ,where there is a spinning prop the water is squeezed through water positioned jets instead,so be like an eddy dredge pump effect without a prop ,advantages are better stronger venturi plus no prop to get things lodged in prop to block it
Sorry to be a complainer, but your camera footage must be designed for viewers to see little or nothing of what you are doing when you're doing it. Nice audio though. Try moving the camera another 30 foot away from the work - for a pod cast.
Mark you do an awesome job in everything you do. Thank you so much for putting this video up.
Those tests are great.
Inovation is Keen's middle name.
Thanks for sharing this technique
Very cool guys!!
Hola,de cuántas pulgadas es la bomba,de caudal o de presión?, gracias
Hello please tell me here at 4 (102mm) inches by 2 springs on how many in mm?
Hello, do you have a reference for the flow meter ? thank you

How can I get one of those
I am interested in suction devices. Is it still for sale?
Hola me gustaría comprar la draga más imformacion gracias saludos desde perú
