Design Fully automatic pressure booster system with two or three vertical high-pressure
pumps (3) for ensuring the required supply pressure
Function KSB Delta Primo F:
Either two or three pumps are controlled and monitored by a microprocessor control
unit (BoosterControl Advanced). The first pump is started up when the pressure falls
below the set start-up pressure. Additional pumps are sequenced in automatically in
line with actual demand. When demand decreases, the pumps are sequenced out
again as the stop pressure (start-up pr delta p) is reached. The pump that has
been started up first will be stopped first. The pumps are automatically started up in
a different order for each new cycle. The actual pressure is measured by an analog
pressure measuring device (pressure transmitter). The function of this pressure
transmitter is monitored (broken wire detection).
This ensures equal distribution of pump operating hours.
If a duty pump fails, the next pump is started up immediately. Via a volt-free contact
a general fault message can be transmitted (e.g. to the control station).
KSB Delta Primo VC, SVP
Either two or three pumps are controlled and monitored by a microprocessor control
unit (BoosterControl Advanced). Each pump is operated on a frequency inverter and
controlled by the control unit so as to ensure a constant discharge pressure of the
pressure booster system.
As the demand increases or decreases, peak load pumps are started and stopped
automatically. As soon as the demand increases again after one pump has been
stopped, another pump which has not been in operation before is started up. When
the last pump has been stopped and the demand increases again, the next pump in
line is started up on a frequency inverter. The stand-by pump is also included in the
alternating cycle.
The standard setting is for the pressure booster system to start automatically as a
function of pressure. As long as the pressure booster system is in operation, the
pumps are started and stopped as a function of demand (standard setting). In this
