Hi from Kansas

Hi everyone,
I'm working on a project, well I'm researching it. 
The project is a paddle wheel style pump.
My goal is to move as much water as possible about 8" high with as little power as possible so that hopefully I can run it off of batteries (2 12v's) and solar.
I do not mean to intrude on the site, it just looked like the people here would have a very good idea of what could and couldn't be done with paddle wheels.
This set up is to put in my pond.  It's a bit of an experiment.
Any input would be appreciated.

I came across these http://www.aquaculture-product.com/english/equipment/aerator-e1.htm .
They get a lot of aeration for 1 HP!
I want to move water just a little ways up an over a float and back to the pond, so would run mine much slower to use less energy.

Hi there Kent, anyone who uses a wheel to move water is welcome on here. I'm thinking the use you intend is very much like a mill wheel but in reverse where the wheel is lifting the water from a lower  level  to a higher one, am I correct ? If that is the case then water scoops, rather than simple  floats which would push the water past a hull, will  be the most effective way. Whichever way you go then pease keep us informed of your progress  / research.

cheers

Thanks for the welcome!
I envision a paddle wheel around 1.5 meter tall, 50 centimeters wide, with the paddles close together.
I would have the paddle wheel in a trough the same radius as the outside of paddle wheel. There would be sides on the trough to keep water from going around the edges or under the paddles.
The trough would start at dead center under the wheel, then go about 1/8 the way around the loaded side.  Thinking this would leave the trough dumping the water out about 20 centimeters above water.
My rough math gives me about 160 gallon per revolution?
If I only tried for 1 or several rpms could I get by with a very little power?
All thoughts would be appreciated,  Kent

Hi zhkent

Welcome to the forum you should get some good information here.

Why not start a thread entitled 'paddlepump' or similar in the research or other craft section of the forum?. We try to keep this bit of paddleducks just for introductions.
You should get more response in the other sections too!

All the best and enjoy.
