Amarine-Made 12V Stainless Shell Submersible 3.2GPM 10A Deep Well Water DC Pump/Alternative Energy Solar Battery

Genial funciona con una batería de coche sin problemas

I purchased this pump three years ago for a shallow well, 23'. It recently stopped pumping after I agitated the well with an air lift trying to remove a few feet of sand in preparation of the upcoming drought. This year I fear the well will go dry without going down a few more feet. My shallow well has filled in about 36" in the past 65 years. It does not sound like much, but that is a lot of water with a 4' caisson. The water is hard. While the inside of my pump looks good, the label isrusted because manufacturer must use metallic ink. The electrical connections were also rusty, but everything else is fine. For the past three years this pump has moved 1300 gallons of water per day.I hope this helps.

Desde un principio la bomba funciono intermitentemente con un sistema solar de 450 watts, aun cuando el sol estaba a todo, utilizando controlador de carga y baterias no ayudo.La operacion intermitente continuo hasta que la bomba dejo de funcionar, justo dos dias despues del tiempo limite para hacer la devolucion. No la recomiendo.

Don’t make the same mistake as I did. In my well, the static water level is at 92ft. I put the pump 130ft into the well. I first installed it with 14ga wires. I bought 14ga wire because I thought about it like I would for 120 volts. The pump draws 10 amps. 14ga wire is plenty for 10 amps, but... I did not take into account the voltage drop over the 135ft of wire. The pump was performing very very poorly after initial install. It was only pumping about 1/4 of a gallon per minute. After thinking about it, I calculated the voltage drop, and found out the pump would only be getting 6 volts with my wire! I got 10ga wire and pulled the pump up and ran the new wire. The 10ga gives me 2.5 volt drop. I’m using my truck to run the pump, so the input is 14 volts. The pump is now getting 11.5 volts after the 135 feet of wire. The pump now performs quite well, pumping about 1.3 gallons per minute. The new problem is that it cycles. The thermal protection is apparently very sensitive on this pump. It initially runs for about 5 minutes solid before shutting down for about 1 minute. It then runs shorter and shorter periods until is levels off at about 1 minute on, 1 minute off. This is ok for my application, but keep that in mind for your application. I still gave it 4 stars, despite the cycling, because it’s so cheap.

Our well is 110 ft deep. The static water line is at 62 feet, and I have this 12 volt DC Pump set at 76 feet. Using a 12 volt marine battery, I can pump for about 36 hours! HAven't measured the actual flow Rate, but the pressure at 120 foot head (the distance beyond the top of the well, is roughly like that from a typical water fountain at the gym or at school. VERY pleased. I have had the pump for two months, and have moved well over 500 gallons of water.
