For example, if the Start pressure is 4 bar, the Stop
pressure is 6 bar and the DP value is 2 bar, the Slave
Pump will start when the pressure reaches 3 bar:
(P.Stop 6bar – P.Start 4bar)= DP 2bar
(DP 2bar : 2) = DP ½ 1bar
Slave pump Start pressure =
(P.Start 4bar – DP ½ 1bar) = 3 bar
Master pump Start pressure
= 4 bar
Master and Slave pump Stop pressure
= 6 bar
(+ 50% of the Start pressure value)
DP 1/2
= 1 bar
Slave pump Start pressure
= 3 bar

PROTECTIONS AND ALARMS
The protections and alarms are indicated on the front regulation and control panel located on the cover of each
pump by the lighting of the respective leds and at a distance by the optional relay only in the Pressure and flow
switch and Pressure boosting function.
