I am looking for a recommendation for continuous duty 12 volt water pump for my 12 volt water maker. I need something in the range of 4 gallons per minute with a maximum pressure of about 40 lb.
the pump I have now is shutting off due to heat after a bit of time in the south Florida 95 degrees temperature
If you don't find a motor, you can add a 1 gallon expansion tank and a pressure switch.
So the pump brings the tank to pressure, shuts off, and gets a rest cycle while the expansion tank supplies pressure.
I used this setup on a 12v system I had. Worked fine.
