which pump

You need to know the head loss through the piping loops and the GPMs required to deliver the heat...whoever figured the job for you or whatever program you used should give you that info, then select a ciculator from the pump curves of that particular circulator. Don't guess at it....it's not worth the pain and misery of having to go back when the system doesn't deliver the heat!!!
