  • Suggestions For Water Pump

    Hi everyone,

    I'm in the process of setting up an aquaponics garden to be run entirely off of solar. I'm looking for a reliable, durable and energy efficient pump to run the system. The pump needs to circulate roughly 6000L per hour. I'm also in rural Ghana so my options for shopping/shipping are limited. Here's a link to one of the companies in Accra but I can't tell if what they have in stock will suit my needs (they haven't responded to my emails). pumptechgh.com

    Thanks

    The pumps on that website are rated in meters^3 per hour
    Is it correct that 6,000 Liters per hour converts to 6 Meter^3 per hour ?

    From that website the PS2-600 CS-F is rated at Max Flow Rate 8.3 Meters^3 / hour
    I do not see amps or watts rating for the motor

    What is your LIFT requirement?

    Grundfos is a good manufacturer.

      Yes. 1,000 liters will fit very nicely in a 1 m^3 container. As a matter of fact, exactly.

        if all you want to do is move water around the most cost efficient way I can think of is a 12 volt electric boat trolling motor. Pumps and pipes cost money and are costly to operate. Design your pond around the current the motor pushes out and I think you would be in the 100 watt per hour range or 2.4 kw per day.

          I think, the water flow in an aquaponics garden is very different than a pond.

            I have a koi pond so might be of help.

            The most efficient way to move/circulate water is with an air-lift setup, which can typically be accomplished with <100W. To lift water any more than a few inches will require a true pump which will take more power. Depending upon your requirements, there are some very efficient water pumps, but they're also Very expensive. Google "Flowfriend pump" for such a unit.
