How to determine Yang Cheng for a metering pump
Thread Content
Hello everyone. My company is helping a company select a metering pump for use in its system. The pipeline in question is 50 meters long with a diameter of 50 mm, and it is used to transport concentrated sulfuric acid. The dosing point is 3 meters higher than the metering pump, and the required flow rate is 1000 liters per hour. What pressure would be appropriate in this case? Can the pressure setting of a metering pump be calculated based on various resistances? Thank you
As long as the maximum pressure is greater than the calculated head, it’s fine; the outlet pressure can be adjusted during use.

As for how to adjust this pressure, the flow rate can be adjusted instead. Are you referring to backflow regulation?
