Setting the pump speed
The pump speed can be selected on the pump. The default setting is high speed (III). If the water flow in
the system is too high (e.g., noise of running water in the installation) the speed can be lowered (I or II).
The available external static pressure (ESP, expressed in mH2O) in function of the water flow (l/min) is
shown in the graph below.
