How is the rated flow rate and head determined for a pump that is used for multiple purposes? For example, a pump might need to pump liquid to two tanks located in different places during use – one on the second floor and the other on the sixth floor. How should one determine its head capacity in such a case? As determined for the sixth floor, when it is used on the second floor, the head pressure is too high
Based on the flow rate at the sixth floor, if a pressure below the full range can still achieve the desired flow rate, select a pump with a relatively lower head
If efficiency requirements are not strict, variable-frequency or multi-stage pump taps
