Default New higher capacity ro watermaker membranes available from DowFilmtec - needs pump design changes?

Ah, I see. They raised it about 20% from .4 to .48 gpm. I will have to
update my Rosa program and see how that will effect my flow. I have
everything built but will not buy the membranes until the boat is
launched. It would have to be compatable because there are to many
systems out there tuned for the old product rate. I can see one thing
that I do need to check. I sized the diverter solenoid for .6 gpm at 5
psi. If it puts out much more the product side back pressure is going
to rise and I will have to up the pump pressure to compensate.

they've improved the line and not told the world so the mfg can clean
out old inventory - same old story
