The hourly flow rate of the pump ÷ 60 ÷ the number of strokes per minute of the pump × 15=the actual minimum volume required by
the damper
The minimum volume of the damper required to reduce 90% of the pulse can be obtained by multiplying the metering capacity (ml) of
each stroke of the metering pump (or diaphragm pump) by 15. Note: (This calculation method is applicable to single head pulse type
pump bodies, multi head pumps are discussed separately.)
