Minimum nominal flow rate
To prevent overheating of the internal pump components, make sure that a minimum water
flow is always guaranteed when the pump is running. If this cannot be achieved, then a
bypass/ recirculate line is recommended.
WARNING:
Do not run the pump against a closed discharge for longer than a few seconds.
For continuous operation the minimum flow rate recommended is specified in the following
table.
