Glossary
Glossary
Accumulator
Pressure losses may occur in the piping
downstream of the pressure booster system as a
result of losses due to leakage. The accumulator
serves to compensate for pressure losses and
minimises the frequency of starts of the pressure
booster system.
Certificate of decontamination
A certificate of decontamination is enclosed by the
customer when returning the product to the
manufacturer to certify that the product has been
properly drained to eliminate any environmental
and health hazards arising from components in
contact with the fluid handled.
Dry running protection
Dry running protection devices prevent the pump
from being operated without the fluid to be
handled, which would result in pump damage.
Energy-saving mode
Setting designed to avoid the energetically
inefficient operation of a pump at minimum water
consumption.
Filling the accumulator
Function to fill a (discharge-side) accumulator; it
prevents pump sets from starting if only a very
small amount of water (e.g. caused by leakage) is
required.
IE3
Efficiency class to IEC60034-30: 3=Premium
Efficiency (IE = International Efficiency)
Manual mode
Direct operation on the power supply network,
independently of the control unit.
Switchgear and controlgear assembly
Control cabinet with one or several control units/
switchgears and electrical equipment.

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 pressure+ deltap) 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

way it is ensured that the individual pumps operate only in line with actual demand.
If the demand drops towards 0, the pressure booster system slowly runs down to the
stop point.

1 volt-free general contact is provided for reporting warnings and alerts.
4.7 Noise characteristics
The pressure booster system is available with different numbers and sizes of pumps.
For the noise characteristics refer to the operating manual of the pump set. To
calculate the expected total sound pressure level, add a defined value to the
individual pump set’s expected sound pressure level.

7.8 Operating modes
7.8.1 Manual mode
Manual mode is reserved for emergencies. Continuous manual operation would lead
to waste of energy and water and cause the fluid handled and/or the pump set to
overheat. The pump sets can be switched to manual mode depending on the design
of the pressure booster system.
▪ Standard design: By making the appropriate settings at the display, one of the
pump sets is operated directly on mains power for 10seconds, independently of
the control unit. After the 10seconds the pump set is stopped automatically.
▪ Design with supplementary equipment: By selecting the appropriate setting via
the manual-0-automatic selector switch, available as supplementary equipment,
every pump set is operated directly on the mains, independently of the control
unit.
7.8.2 Energy-saving mode
CAUTION
Hunting (excessive starting/stopping) of pressure booster system
Damage to the pumps!
▷ Only activate the energy-saving mode if a sufficiently sized accumulator is fitted
on the discharge side.
NOTE
No recommendation can be given for the parameters of the energy-saving mode.
The values depend on the system installed and can only be defined at the
operational pressure booster system installed on site.
In conjunction with a very large discharge-side accumulator, the energy-saving mode
ensures that the pressure booster system runs at an energy-efficient operating point
when required to supply very small amounts of water. If a very small amount of
water is consumed, the pressure booster system fills the downstream accumulator
and stops. Any small water volumes required can then be supplied from the
accumulator.
ü The accumulator has been filled. (ðSection7.9.1,Page37)
ü Logged in at Service level.
1. Close the discharge-side shut-off valve slowly until only a single pump set is left
running and delivering a small amount of water.
2. Read and record the pump load in parameter 1-1-2.
4. Set parameter 3-11-1 (energy-saving mode) to ON.
5. Set parameter 3-11-2 (direct OFF) to ON.
The setting OFF (flow detection) should only be selected for difficult site
conditions and by an expert. (ðSection7.9.2,Page37)
6. Enter the pump load value in parameter 3-11-3 (stop speed %).
7. Set parameter 3-11-4 (time Direct OFF) to define the time period the pump is to
keep on running in order to charge the accumulator before stopping.

7.9 Functions
7.9.1 Filling the accumulator
The energy-saving mode prevents the pump sets from starting if only a very small
amount of water (e.g. caused by leakage) is required. The required fluid can be
supplied from the accumulator (discharge-side accumulator).

accumulator before stopping.
ð The accumulator is being filled.
5. Set the setpoint to 0.
ð The function is disabled.
7.9.2 Setting flow detection
When one pump set is operated, the control unit checks the quantity of the fluid
handled.
The pump set’s speed is slightly lowered within a configurable time interval. If the
actual value is within the bandwidth, the control unit triggers the filling of the
accumulator and stops the pump set.

7.9.3 Setting Delta P (dynamic pressure compensation function)
The dynamic pressure compensation function is a dynamic flow rate-dependent set
value re-adjustment. The system responds to decreasing flow rates by automatically
increasing the set value to compensate the pressure losses in the piping.
The remote ON/OFF connection is an NC contact. When this contact is open, all
pumps in operation switch off in succession after a configurable stop delay. A
warning message is output (yellow LED). When this contact is closed, the pump sets
start up again in line with demand. The warning message is cleared.

Check the automatic switching functionality.
Check the cut-in levels and cut-out levels.
Check the inflow, inlet pressure, dry running protection, flow monitoring and pressure
reducer.
8.2.4 Setting the pre-charge pressure
WARNING
Wrong gas
Danger of poisoning!
▷ Use only nitrogen to charge the accumulator.
CAUTION
Pre-charge pressure too high
Damage to the accumulator!
▷ Observe the manufacturer's product literature (see name plate or operating
manual of the accumulator).
The accumulator’s pre-charge pressure (p) must be lower than the set start-up
pressure (pE) of the pressure booster system.
The best storage volumes are achieved with the following settings (mean value):
▪ Value 0.9 at start-up pressure > 3bar
▪ Value 0.8 at start-up pressure < 3bar
Example 1 pE=5bar
5bar×0.9=4.5bar
With a start-up pressure of 5bar the pre-charge pressure of the accumulator must be
4.5 bar.
Example 2 pE=2bar
2bar ×0.8=1.6bar
With a start-up pressure of 2bar the pre-charge pressure of the accumulator must be
1.6 bar.
Checking the pre-charge pressure
1. Close the shut-off elements fitted underneath the membrane-type accumulator.
2. Drain the membrane-type accumulator via the drain valve.
3. Remove and store the protective cap of the membrane-type accumulator valve.
4. Check the pre-charge pressure using suitable equipment (e.g. tyre pressure
gauge).
5. Fit the protective cap of the membrane-type accumulator valve.
1983.811/02-EN
Filling the membrane-type accumulator
1. Remove and store the protective cap of the membrane-type accumulator valve.
2. Add nitrogen through the valve.
