Hydronics/Water Flow (SC-2000)
• The chart below represents the pressure drop (Ft of Head) versus the water flow rate (GPM) for
the SONIC SC-2000. 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 connected piping, valves, strainers, couplings, flanges, etc.
• The table below summarizes the minimum and maximum flow restrictions for the SC-2000:
