Pump selection
Thread Content
When designing, I wanted to create a linkage between the pump’s flow rate and a certain pressure; I’m not sure whether it would be better to use an variable-frequency pump or to install a control valve at the pump outlet for this purpose. Please give me some guidance.
Reply to 1# pksinixu: Just add a frequency converter and a flow meter, and that’s it.
Using a variable frequency drive provides greater stability; however, when using interconnection, there are too many factors to consider, which can affect the stability of the system
For positive displacement pumps, flow rate is related to rotational speed and has no direct relationship with pressure. This is not the case for centrifugal pumps; however, it is better to adjust the pump rather than adjusting it through the pipelines

Hydraulic diaphragm metering pumps can meet your requirements.
