Dc pump ???
I want to make up a smaller ro unit for this upcoming syrup season. My game plan is to use 3- 400gpd membranes for my system. Question ?I have very limited 120 vac but have access to lots of large dc batteries ( 4d - 8d ) , has anyone out there ever built a ro system that runs off a battery powered booster pump?????
Thanks for any advice given
2014 100 taps 65 l of syurp
2015 50 taps 20 l of syurp
2016 150 taps, 160 l of syurp made
2017 plan is 150 taps , and will see what happens
2018 200 tap , 25 on my first 3/16 gravity system, 250 of syrup
2019 250 taps , all on 3/16 with 12 volt diagram pump ( 300 l of syrup)
2020 same 250 taps , time to make a small ro unit
A 12V DC diaphragm pump might work. You will need enough battery and the right pump. First determin what pressure you need to run at, then build it to fit.
Another way might be to run a generator and a AC pump, if you study that route make sure the genny can handle the start surge.
Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
I see there are 12 diaphragm pumps that are rated for 150 psi ? Is that enough pressure to run a ro unit ??? And next big question Is just as important, how much flow would a pump have to be rated for to run 3 - 400 gpd membranes

Dc booster pumps
The booster pumps most people use on these style of RO’s, like the 8800, are 24v dc anyways. Just connect 2 12v batteries in series and your good to go. The first RO I built was this style and I initially ordered the wrong power supply so this is what I did until I got the correct one.

A friend of mine sent me a pic of his booster pump and it showed on the data plate that yes the pump voltage is 24 volt , but it was showing it was 24 volt ac not dc ???
