The same graph in Fig.6 shows in green other characteristic curves
corresponding to reduced rotation speeds of the same electropump. By
automatically modulating the rotation speed of the electropump, the in-
verter allows it to move its operation from one of the characteristic curves
to another, maintaining the constant set pressure value (SP). Practically,
the resulting curve of the system controlled by the inverter becomes the
one shown in Fig.7 (considering a default SP value = 3.0 bar).

Q (lt/1')
This means that, with SP = 3.0 bar, the system is able to ensure the
constant set pressure to utilities that require flow rates between 0 and
90 litres/minute. For higher flow rates the system works according to the
characteristic curve of the electropump at maximum rotation speed. For
flow rates lower than 90 litres/minute, as well as ensuring constant pres-

sure, the system reduces the absorbed power and therefore the energy
consumption.
The above performances are to be considered measured at
ambient temperature and water at about 20°C, during the first
10 minutes of motor operation, with water level at suction at a
depth of no more than 1 metre
As the suction depth increases, the performance of the electro-
pump decreases.
