6 gpm DC pump for 24-hr operation
Hello- I looked for other threads with this discussed but didn't find one that I could use. I have a local farmer who wanted to run his 6 GPM water pump 24/7 through the winter months. He does this for cattle troughs to keep the water from freezing. He currently uses batteries charged at home and delivers a new battery each day. The pumps he uses now are around 14A and the batteries/panels for that amount of power is more than he wants to pay for.
Are there any lower amp pumps available that are in DC that would allow him to skip an inverter and run straight from the batteries/panels at less than 14A? I see some Flojet pumps, etc., but I am not familiar enough with the specific types of pumps (diaphragm, centrifugal, etc.) to know what types would be good.
I did tell him to try use other methods such as heaters or passive designs, but he knows his current method works and he wants to keep using batteries. I just thought it was an interesting problem to help him with.
