Pat's 2024 Yuba Bash!

I don't see power or weight being an issue with battery. Issue is thst type battery doesn't like water. It explodes. Y'alls main concern should be making it safe water proof

Armorage batteries . They custom make them. A s are amazing

We had David Frank 's running around 60v things a beast 😈

What is the point of doing this? Is it to be quiet or another reason? I’m guessing the weight difference wouldn’t be much different than a gas motor. If noise is an issue, wouldn’t it be better to create a “silencer” for the exhaust that doesn’t bog down the motor? What’s the longevity of the battery/batteries? Could a solar panel be hooked to it to extend operating time? How about a small portable pelton wheel attached to an alternator? I’m honestly curious

Contact Hybrid Technology in San Bernardino, Norm there builds an impressive small form tesla pump, huge flow and pressure. Small engine.

Which printer did you end up with? I'm looking into the new Creality K2... Got some ideas I've been wanting to try out

They have AC centtifacal spa pumps, 220gpm, changing to DC can't be that hard, four 12v batteries equal 48v many electric bike motors run on 48v

Vortxrex Gold Mining Can't wait to hear how you like it. I run mine on a 54v

I just got into e pitbikes and I’ve been doing a lot of research into upgrading it. Have you looked into e motorcycle motor setups? All the power you need, the battery research is already there and they are highly programmable.i think $300 would get you a motor with enough power I think for a p90. Fardriver controllers are run in the high end emotorcycles and range from 36v up to 96v and up to 1000 amps depending on unit. The72v360amp unit is $359. There’s a new style controller called Vesc and they are along the same high voltage/high current ratings but around $100. Amazon has the 12v100ah lipo batteries for $159. It looks like you’re running a brushed setup for the motor. What kind of controller are you using?

Mark Keene and David Frank: My development of an electric-powered water pump has been ongoing for five years. During the same period, I have also been working on designing a nozzle for a suction dredge. I use advanced CAD software, including ANSYS, for theoretical designs, which are then validated through practical testing. The pump is still under development and undergoing optimization. Keene blogs are great, but they lack one crucial piece of information—it is impossible to precisely determine the nozzle diameter for a suction dredge, such as a 2" dredge, without considering the pump's characteristics. It is generally accepted that using a pressure pump is necessary to achieve good results. While this is partially true, the determining factors are kinetic energy and efficiency. It's great that we're both working on electric dredges. Let's see in the new year how far each of us has progressed toward better results. David, is it allowed in the US to use 54-60V in a water environment? Here in Europe, we have a maximum of 24V (DC). David, to answer your questions: the operating pressure for the dredge is currently 0.65 bar with a power input of 350W, and the maximum pump pressure is 1.42 bar. Even now, the 2" dredge is performing (working) well (with custom design power jet). At the beginning of 2025, I’d be happy to make some field videos so that my words aren’t just empty talk.

I wanted your whatsapp contact?

Wondering if you can build a pump like a oil pump in a automotive engine

I got a akita 18v to 12v adapter that I have used on a high banker and it worked fine the advantage I see is tool batteries are lighter and easier than a 12v car battery and when you get old weight matters

It would be very cool if we could get the battery weight down.

What you are doing sounds super cool.🧚

Inclosed impeller, or maybe rubber impeller like on gear pumps.

Multi stage pump like a fire pump? Volume and pressure stages being separate may help reduce the load

Need to build a more efficient pump and nozzle. If you want to use a current pump I would look into the qs-138 motors. From there you can fine tune the power and rpms etc. could probably run a p90 on the smaller qs 90 or 120 motors.

DIY high-performance pump Voltage: 12-20V Water-cooled motor and electronics Smooth speed control Works great with a 2" suction dredge

What electric dredges have you used and why where you not impressed?

I built an electric set up in one of your 2” dredges a few years ago… Building them is half the fun for sure !!!
