2 circulators single zone

hello, my only question is, I have one thermostat and a circulator on the supply, I have a loop that needs its own circulator. Can I wire both circulators together inside the boiler wiring so whenever the thermostat calls, both pumps activate? I want both pumps to activate simultaneously all the time. On a single zone one thermostat. Do I need some kind of relay? Or just wire in parallel inside the boiler. Thanks

    I am sure it can be done but more information and pictures needed. Do you have a loop with no circulator? Doesn't sound right

    I just need to add a circulator to a loop that cast baseboard radiators. The rest is big cast iron rads. Can I have 2 circulators wired inside the boiler so both pumps work as one essentially?

    Yes you can. Not difficult. Also pipe the pumps in parallel, so you will need piping to split the zones into two zones — and you will need to have balancing valves to get the flow riht.
