Please discuss how to start and switch off pumps that have a minimum flow line

Set a certain opening for the minimum flow rate before starting the pump

First, open the line for the minimum flow rate; once the pump has stabilized the flow rate, then close the return flow

Generally, the minimum flow line is equipped with an orifice plate to limit the flow rate. It can stay on all the time.

The small pump has flow restriction, while the large pump is controlled by a valve.
