Hydronics /Water Flow (Sc-3000 / Sc-4000) - Harsco Industrial SC-1500 Owner's Manual

Hydronics/Water Flow
The chart below represents the pressure drop (Ft of Head) versus the water flow rate (GPM) for the SONIC
TM
SC-3000 and SC-4000 boilers. This information is useful to help size an appropriate circulation pump.
Keep in mind this pressure drop represents the boiler only, additional consideration is needed for any
connecting piping, valves, strainers, couplings, flanges, etc .
The table below summarizes the minimum and maximum flow restrictions for the SC-3000 boiler:
