The pump I have is a:




Goulds 18GBC1014G4 1 horse power

28GPM Max flow

6GPM Min flow

Heads to 470 ft (203PSI)

I was hoping this would work for a 4"x40" membrane and perhaps two in the future. I am not sure on sure what the pump is capable of doing, it seems like it would work for a homemade RO.
Any in put on sizing would be great. I did find the manual on line, just not that familiar with curves and such.

That should get you great start for couple 4x40 membranes.

I am assuming 3/8 needle valves on a unit this size are ok or would I need something bigger?
