    Circulators in series ?

    I am in a situation where I need a high head circulator for my heating system which I would like to avoid. Can I put two smaller circulators in series?

    I need about 21 feet of head at 4gpm.

    The UP15-100 is a better idea. Around $100 1 pump , head is right where you want to be at 4gpm

    Try this pump. Exactly what your looking for, around $100.
