The fully automatic pressure booster system pumps the fluid to the consumer
installations in the set pressure range with a non-self-priming single-stage centrifugal
pump.
The system is controlled and monitored by a micro-processor control unit (1). The
duty pump is started up when the pressure falls below the set start-up pressure and
stopped when the stop pressure (start-up pr delta p) is reached. The pumps
are automatically started up in a different order for each new cycle to equally
distribute the pump operating hours. A minimum run time of 180 seconds is factory-
set for each pump in order to limit the frequency of pump starts. The operating
status is displayed via LEDs.
The fire-fighting system is factory-set to the values listed in the following table:
