To much pressure?

[virtual reality]

So I bought a R.O. buddy system. 50gpd. I know I will need a pressure pump.
I looked at the they sold, and did not like the reviews. So I ordered a aquatec
one. I have not hooked it up yet. I just seen now that the D.I. cartridge says only
30 psi. How is that going to work. I am so confused. Also running from a Well system
If anyone would like to share some knowledge, I could use it.

The pump is supplying pressure to the RO membrane, once it leaves the membrane and into the di canister it's not under much pressure anymore
