The fully automatic pressure booster system is equipped with a non-self-priming
vertical high-pressure pump (1) for pumping the fluid handled to the consumer
installations at a constant pressure.
The pump is started as a function of pressure and stopped as a function of flow by a
fully automatic control unit. If the pressure drops below the pre-set pressure, the
pump starts up and the frequency inverter controls the unit to maintain the set
pressure, so that the pressure is kept constant.
As the consumption decreases, the speed is reduced. At zero flow, the pressure
booster system stops after a set after-run period (45 to 360 seconds).
A key for manual operation is provided on the control panel. In manual mode the
pump operates at the pre-set minimum speed, independently of the automatic
system (pressure transmitter) or an External ON/OFF signal.
NOTE
Continuous manual mode is reserved exclusively for emergencies!
Continuous operation of the pressure booster system in manual mode may result in
waste of energy and water.
In manual mode, a minimum flow (see table below) is essential to prevent the fluid
handled and the pump from overheating when no water is consumed at the
consumer installations.
