    Hello Ladies and Gentlemen

    I am Shine. I am new here.

    I want to know something that will change my country.

    Please kindly help me.

    We have big fish ponds in my country.

    People pump huge amounts of water into the pond from the water stream which is just beside the pond.

    The regular system with generators consumes lots of fuel.

    So, we need a special DC pump which can pump huge amount of water but through a short distance.

    Is there any system that suits our need. We have millions of people who spends billions of money for everyday fuel.

    Help!!!

    Greetings... Is there any difference in elevation between pond and stream... Perhaps a siphon would be adequate ?

    Yes there is elevation . But the pond's water level is lower than the stream's water level.

    I doubt DC pumps cannot pump that much water. ???

    if the pond is lower than the strean, a syphon would work, and consume no fuel.

    If the pond is lower than the stream, I do not see how it is not already part of the stream.

    What country are you in?
    Can you post a map of the area or a link?
    How much water per day do you want to move?

    Why doesn't the pond dry out if you are pumping water out of it?

    Elevating a certain amount of water by a certain height has a fixed energy requirement, there is no way round this. The only thing you can work on is the efficiency of your system and the more stages you go through the less efficient the system. Just get a petrol/diesel pump and use that. Using a generator and AC/DC converter will be less efficient.

    Hopefully you are not involved in a project such as this producing Basa and Catfish.

    As already stated..
    If the pond is lower than the stream then you simply need to use a siphon (no fuel/pumps needed at all)
    May need a pump to get the siphon started but after that it can be taken offline

    Thanks Bernoulli..
    Siphon.. I love it..keeping my fish tank/sump system running quietly for years..

    Why a siphon? Why not just a ditch? Let the water do it's thing...

    If the stream has a decent flow rate, you can use an Archimedes screw powered by a paddle wheel on the end that dips into the stream.

    I assume people wouldn't be using pumps if they didn't have to.

    But I don't see the connection to needing a "special DC pump". What's needed is a more efficient pump that runs directly off the fueled engine, eliminating the generator.

    I'm skeptical that there is a wide demand for this. It's a pretty obvious solution. There's probably a good reason things are the way they are.

    Okay Is there such pump? What about fuel consumption?Thabks

    Yes! A siphon would be okay but the water leve

    Yes! A siphon would be okay but the water level is not always the same. That is why we need a pump.

    That's what I am thinking about. But I have to study about more about ram pump. Thanks

    My country is Myanmar.

    I worked 10 years designing and running ~4000 acres of shrimp farms overseas... The water streams are very unlikely at higher level than the ponds. Description has to be a mental fart. I used two 30,000 gallons per minute 30 inch diameter pumps with 671 DetroitDiesel engines at every farm, for 5~10 feet head.
    The only way to pump some little flow with no fuel expenses is by using the stream speed (likely too slow to be useable) to move a pumping paddle wheel; or a massive solar panels investment.
