Can anyone forsee a problem running two of these in series?

That would give 26 ft of head and 1.5 - 2 gpm.

This happens to be VERY close to Cathar's ideal of 23 ft and 3.5 gpm.

Also, re: an earlier comment about why use two smaller pumps:

I have tried to find pumps in the UK which do these sorts of head pressures, and they don't get any cheaper than about £179. Two of these small Laing pumps cost £100 in the UK and produce 17 ft and 6 gpm (D4) or 23ft and 1.5 gpm (DDC), so I don't understand an argument AGAINST using two pumps?

Maybe things like Iwakis and the like are more easily available / cheaper in the states (I suspect so!)?
