I have a 45gph RO from Next Generation Maple Products and it works great. Like everyone else I have added more taps and would like an RO that will process more sap. The unit I have has a 2.5" x 40 membrane. Could I swap it out for a 4" x 40" membrane and housing?

What size pump does it have ?

As bricklayer said size of pump and motor are the key items in determining if you can add a larger membrane. I too am looking to add another membrane to my deer run ro. I needed to increase the pump size to accomplish this. Fortunately the motor on the unit can handle the larger pump so that can stay the same.
pump size is the most critical thing here. also keep in mind when you re-engineer a piece of equipment it usually goes down in value.

Best thing to do would be to call Next Generation and ask them that question.

I just checked my RO and here are the specs for the pump and motor:
1) motor is 3/4 hp
2) pump is Procon 112A125F11BA 144413-1-1 225psi
If someone can decode if this pump/motor combination would adequately work with a 4 x 40 membrane it would be appreciated.
Thanks

So yours Has a 125 gph flow rate at 225 psi
Without looking up all the specs for membranes I would say that you could upgrade to a 4"
You would have 2.08 gpm of flow across the membrane. Obviously more is better. But I think you'll be ok.
Not ideal. Worst case scenario you will be washing and flushing your membrane more often.
The 1 thing that you have to make sure of Is that you have enough permeate to do a proper flush at the end of the day. And if you foul your membrane what are you gonna flush and clean it with.
With a smaller membrane it takes less permeate to clean.
A 4" will take about 150-200 gallons to flush properly.
100gallons in a real pinch.
