Grundfos BMS Series - BMS Hp Pump

7.2.3 Operating limits
We recommend that you always keep the capacity of the booster
systems within the recommended flow rate and pressure range of
each individual pump.
Note that if there is a risk of exceeding the maximum inlet or outlet
pressure, we recommend that you install a safety valve.
