circulation problem

I have a Hydronic heating system installed in my home, I have added a extra 3/4" line to the system as this is now the longest line on the system I am having problems of it recovering fast enough from on/off. my idea is to install a Booster pump on this line .
Can anyone advice a small pump that can be installed vertical , the system runs on three Armstrong astro 50 inline but I only use two as the third one does not make any differance , I was thinking of maybe using this one if it could be used in a vertical position, though the least work is to install a new pump. Thanks. BL.

Is it possible that a 1/2" pipe would have given you more pressure, instead of more volume?
