When the outlet flow rate of a centrifugal pump remains constant but the pressure changes, what should be done?

Hello everyone, I have a centrifugal pump with a capacity of 400 cubic feet, and the outlet pressure varies between 10 and 140 meters. How can this be controlled? Thank you
If the flow rate changes, how can the pressure remain unchanged?
The pressure change you’re experiencing is a bit too large! Check to see if there’s any malfunction!
The outlet pressure can be adjusted by changing the size of the outlet valve, but the range is too large; it’s not feasible, right?
Check the fluctuations in downstream usage
Variable frequency + outlet control valve + return line, it’s possible

In this way, when the flow rate is low, it is basically recirculated
