http://www.ro-man.com/ro-man_support.html then double click on 'system performance' this is for their own products but it should help.

Depends what  water pressure you got?
My 200 gpd on 55psi ish does me around 320 lts in 24 hours (13.3 ltr/hr)

200 gpd without a booster pump, yes you won't be producing much with that.
The membranes work best with 65-70 psi across them. Get a booster pump for starters.

we have a 300gpd r/o at the mo and a booster pump, is it possible to fit a bigger pump to increase the throughput?

If you look on the RO-Man site it says"Our systems are made in the UK and are pressure tested to 100 psi (7 bar)"

If your booster pump is giving you that then no point getting another one
