  • High lift solar water pump

    Hi, does any one know of a 12 or 24 volt water pump that would pump up to a height of 80-100 meters. That is how high our house is above a creek. I have spare panels and batteries I can use but this would need some sort of high pressure pump I expect. I think it equals 142 psi or 9.8 bar
    Thanks,

    There are multivoltage AC/DC submersible pumps from Grundfos designed for use in wells but adaptable to pumping from a creek. They are available in multistage designs for high lift applications. But the pumping volume and power (and cost) may be overkill for your application.

      The Dankoff SlowPump 1322 can do that with about 200W of solar. It can pump about 0.4GPM (thus the name SlowPump).

        Here's a link to the Dankoff pump, http://www.dankoffsolarpumps.com/solar-slow-pump/

          Note that this is a positive displacement pump, so do not even think of using it where it is easy to close a valve on the pump output without shutting off power to the pump!
          Either the motor will stall and may be damaged or something will break.

            Good point, they may want to use it with a controller and float switch to turn it off when their tank is full. Additionally, it does not tolerate grit, so you must use the cartridge filter with it as well. But if you treat it well, it should last 15 -20 years. Dankoff also makes replacement parts for wearable parts, it is built to last and to be field repairable when needed.

              Pump

              Thanks very much for the advice. I'll have a look at it.
              Cheers,

                how about flow rate required? I suggest AC pump, it is cheaper, and higher efficiency.

                  You might be correct but there are DC pumps that will run directly from solar panels without the need of batteries or inverter for AC.

                  As long as the flow rate doesn't need to be constant or fast the pump speed can vary with the suns intensity yet still move enough water when it is shining.

                  Most AC pumps require a steady voltage which means batteries, battery charger and inverter along with the solar panels. An AC pump may have a higher efficiency but I feel the cost is a wash or even less using the DC pump designed for solar applications.

                    Maybe a high pressure cutoff switch in the circuit to shut down the pump or a 3 way valve to change the flow back to the creek should a blockage on the pump discharge occur.

                      Yes, AFAIK an overpressure switch that requires a manual reset will probably do the job.

                        In fact, AC pump can work only with a pump inverter, no need battery, or others.
                        AC pump working time can be lasting 8-10 hours when it is shining.
                        DC pump should work with controller, AC pump inverter includes control function.

                          Where in the world does the sun shine for 8-10 hours? I think your post is a little off the deep end unless you can provide a make & model number of the AC pumping system that runs on solar without a battery for 8 hours.

                            I'd like to see were any manufactures liturature supports that statement for their AC pumps.

                            My DC pump (Shurflo 9300) doesn't need a controller. I do run a LCB just to get a few more gallons a day pumped. It's max lift is 230 feet so a little below hat the OP needs.

                              What a great post concerning high lift solar water pump!! It seems like really great. But dear I would prefer buying httpCOLON//www.aapowersalesDOTcom/Honda-Water-Pumps-s/1820.htm <honda water pump instead of this solar pump. It highly depends on the weather that may cause problems too!
