Two inch PVC suction nozzle

[@adamfranco173]

This is absolutely fantastic!! I met guy up in Maine working the river with your prototype. It worked flawlessly!!!! I will be building one tomorrow. Thanks for the insight🤘⚒️

[@andresboniface5484]

Really useful especially in our place where ready to use nozzles are rarer than gold. Thank you!

[@pablojmarron2611]

That is fuking brilliant, it is exactly the nozzle I was looking for. I have a two hundred year old Spanish hacienda water source and swimming hole to check.

[@genofromrenoprospector6940]

I'm not sure this is very cost effective considering time and material when you can buy a steel nozzle for $100. But this is an excellent video for the diy guys.

This is the BEST EXPLANATION of a dredge I have seen on utube. You are a star. Are you using a 12v pump or gasoline?

[@randallmonville2310]

5.5 hp gasoline.

[@davidwright8199]

@@randallmonville2310 thanks very much indeed. 😁

[@joelrojes5239]

Parabéns ! Gostei muito . Tenho uma saída da motobomba de pressão a gasolina de 2" polegadas ,,,, esta pasta que você coloca é uma cola ? E onde posso encontrar para comprar ? Obrigado desde já . Parabéns pelo talento e a forma clara de explicar .Att.

Bondo is an autobody filler. Its used to repair dents on car bodies. You should be able to buy it at any auto parts store.

Muito bom. Parabéns!

[@mrgreenswelding2853]

Great idea, but bondo absorbs water. Use a fibreglass reinforced filler instead

I am dredging a hole in my boat slip and saw your video and said this may work. My question I am curious about is that if I use a 4 or 5 foot gravel (in my case sand)suction pipe would that affect the performance? I need to move about 3 yards of sand for my keel to rest in. Thanks for share your video.

[@randallmonville2310]

It will. But it may take a bit of time. You can extend the end of the nozzle. Try it.

[@KevenDRayne]

I'm in (or under) the same boat. Did you have success?

[@erikreinertsen1647]

That has alot of suction. You really seem to know what your doing. I am currently attempting to build a 4 inch nozzle in order to suck sand off a lake bed and pump it behind a new seawall for backfill. I am attempting to pump the sand up to 6' in height. So far I have been able to pump sand but not enough. I dont have good suction. I am running a riverside 2-1\2" high pressure pump powered by an 11hp honda engine. What should my jet size be for my 4 inch system? Do you have any suggestions?

[@MJ69090]

I need to do the same thing and my design incorporates a second pump further up the discharge line, which will act as a booster.

[@TheRodeoRider]

Nice work. But how many hp is of your motor pump? Can I do dredging of a pond with 2 hp motor and this nozzle? If not what should be the min capacity?

[@randallmonville2310]

The "u" piece is to get the high pressure water to the jet.

[@lousimoneau7564]

,hi Randal,,will a 50 cc honda work,,my keen nozzle scree up,nice work

[@randallmonville2310]

50 cc is small. I don't think it will work. Try it though. It may be ok.

[@sirwilliamofpennylot]

Enjoyed the vid, does the "u" piece serve any purpose?

[@jimfamille7025]

and for agent de démoulage take soap for a kitchen.... palmolivei have a friend we know do thatttt is a nice twisttt try thist jim....

[@robmcguire963]

Nice idea Thanks for sharing, sO the size of the inner hole is 1/2 inch correct?

[@christiaanschlechter3797]

any digestions on nozel size need help pleas

[@RedmanOutdoors366]

Nice build I couldn't do it better myself :)

[@randallmonville2310]

REDMAN PROSPECTING thank you.

[@RedmanOutdoors366]

Randall Monville yup happy prospecting

[@christiaanschlechter3797]

+Randall Monville hi I'm also macing a dredge nozel but want to cnow what size nozel works best to create the vacume .any advice pleas

[@randallmonville2310]

Christiaan Schlechter start with .5 inch. Will depend on pump pressure and hose length and diameter of dredge. You can drill it out to make it bigger.

[@MrMolina52]

muy Bueno......gracias!!!!!!!!!!!!!!!!!!!!!

[@sergeymamontov953]

Хорошо придумано. Спасибо

[@djpitr]

well its nice use of my principle :) that i use in my nozzle i made :)

[@StevenSchoolAlchemy]

Great idea!

[@bertramlrezenet9311]

Where's the venturi? 🤔

[@randallmonville2310]

Its the part made with the bondo.

[@rustycreed4638]

Would I need to make some diameter adjustments if I wanted to use a 3000gph 12v bilge pump?

[@randallmonville2310]

I doubt it would make enough pressure to create a good suction. All you can do is try though. Start at .5 dia and increase .125 till you get suction.

[@edmelville9292]

This is so wrong the pressure water has to be introduced immediately after the suction side of nozzle or pressure water will be pushed out of the suction side. I am a mechanical engineer and your design goes against physics sorry😢

[@randallmonville2310]

The pressure water goes over the suction nozzle creating the suction. If you extend the pressure nozzle past the suction inlet it will jam with rocks. You can see it working at the beginning of the video.
