RE: maintain constant head in centrifugal pum by using variable frequency

the drive mfg will program the drive using a PID loop
you will need a setpoint, time interval and gain for tuning the PID loop so it will maintain pressure

Put a pressure regulator downstream of the pump with a pressure gage to tell you that you have the correct pressure.
