    Default ro build help please

    would a 1/2hp myers high pressure pump be big enough to run in a 2x 4x40 system thanks i have chance to get a fair price on the pump its definately in my budget but would like to know if it be big enough before i buy it

    Look up the pump curve to be sure. For good RO action you will need close to 300PSI, but lesser performance can be gotten with pressures down to about 100-120PSI. In fact 300 is only the typical pressure top end for low end R.O's, with the right housing it is not the max.

    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 tried looking at the pump curve but i stupid with some of that stuff an couldn make sense of it.and by housing you mean the 4x40 canisters.they rated for 300 psi.im looking at building a system to take care of approx 800 taps on high vac

    A pump rated to push water up to about 278' lift will be at about 120 PSI. That will not be the same for sap, because the specific gravity is different.

    My 2x4x40 ro has a 2 hp motor, and it can go up to 300 psi. I don't think a 1.5 HP will give you 300 psi, but it should give you over 200 PSI which would remove at least 50% of the water in one pass from over 200 gal.

    If you want to get to 800 taps on high vacuum I would think you would want a system that would do at least 300 GPH, 600 would be better.
    First introduced to making maple syrup in 1969
    Making syrup every year since 1979
    3 x 10 oil fired
    Revolution syrup and max flue pan
    Almost 1300 taps total with 900 on high vacuum
    Bought first Marcland drawoff in 1997, still going strong.

    is your system homemade or a factory set up.if i can make something that removes half my water in a pass how long in time wise from 200 gal would this take approx.i just need a starting point somewhere.this season was a killer for me.sap was 1-1.5 all season long.i can reduce about 45-50 g an hr while boiling.thank you for your help.likely im sure i will have alot more questions as i go along.pretty sure im gonna purchase the 1.5 hp pump as so far its the only deal i came across besides the 1/2 hp an that be too small.

    I'm sure you could build one of this size but at what cost, I don't know. I bought my 600 GPH machine from H2O. When planning your build make a complete list of everything you need. If you start buying parts and pieces as you go you may find you are spending way more then you expected. One of the things I don't see included in some of the home made units is a wash tank, a way to protect it from to high of a temperature and a heater if you are not going to let the pump create the heat as it washes.
