Gpd?

[1efddd]

Hi All.
I'm wondering if I used a procon 250psi pump and 1 - 4" x 40" membrane how many gpd can I do?
Thanks for any input.

kind of need to know the gph of the pump

That is the part I don't know. Are most of the procon carbonator pumps roughly the same gph or ??? Don't know much about them.

No, they vary drasticly. When you get into larger RO's flow rate is usually measured in GPH not GPD? For a single 4x40 I used 190 gph procon which is the minimum size you would want to use. Some use up to 330 gph. You should be able to remove 15%-30% water per pass depending on sugar content. So say at 20% with a 190 gph procon you would remove 38 gph of water. This is about what I do on average. And you do NOT want a pump with pressure relief. Pressure should be regulated with a needle valve and a high pressure switch.

1efddd,
Look for the model number on your procon pump. The numbers to the right of the first letter will be pump GPH, the last numbers are pressure

Thanks for the replies and the good info. I did find that the pumps vary a lot with some research. I am running a rig I made up with 3 - tw30 1812 membranes and it works awesome but it's too slow. I need to up production. I can cook it off faster than the ro will condense it. Time to spend more money on this "hobby". When I started all of this maple stuff I sometimes think I should have just bought a tanker of syrup and been done with it but then I would have missed out on all of this fun!! LOL
