Glossary
Accumulator
The accumulator serves to compensate for
pressure losses in the piping system downstream
of the pressure booster system which may be
caused by the consumption of small quantities of
water. As a result, the frequency of starts of the
pressure booster system is minimised.
Braking resistor
Takes up the braking power produced during
generator operation.
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.

The warranty relating to the operating reliability and safety of the pressure booster
system supplied is only valid if the equipment is used in accordance with its intended
use. (ðSection2.2,Page8)
2.9 Electromagnetic compatibility (EMC)
2.9.1 Interference emission requirements
The EN61800-3 EMC product standard is relevant for electric variable speed drives/
control systems. It specifies all pertinent requirements and refers to the relevant
generic standards for complying with the EMC Directive.
Frequency inverters are commonly used by operators as a part of a system, plant or
machine assembly. It should be noted that the operator bears all responsibility for
the final EMC properties of the equipment, plant or installation.
A prerequisite or requirement for complying with the relevant standards or the limit
values and inspection/test levels referenced by them is that all information and
descriptions regarding EMC-compliant installation be observed and followed.
In accordance with the EMC product standard, the EMC requirements to be met
depend on the purpose or intended use of the frequency inverter. Four categories
are defined in the EMC product standard:
Table4: Categories of intended use
Category Definition Limits to EN55011
C1 Frequency inverters with a supply voltage under 1000V installed in the
first environment (residential and office areas).
Class B
C2 Frequency inverters with a supply voltage under 1000V installed in the
first environment (residential and office areas) that are neither ready to
be plugged in/connected nor are mobile and must be installed and
commissioned by specialist personnel.
Class A, Group 1
C3 Frequency inverters with a supply voltage under 1000V installed in the
second environment (industrial environments).
Class A, Group 2
C4 Frequency inverters with a supply voltage over 1000V and a nominal
current over 400A installed in the second environment (industrial
environments) or that are envisaged for use in complex systems.
No borderline/
boundary1)
The following limit values and inspection/test levels must be complied with if the
generic standard on interference emissions applies:
Table5: Classification of installation environment
Environment Generic standard Limits to EN55011
First environment (residential and office areas) EN/IEC61000-6-3

Category to EN 61800-3 Limits to EN55011
≤ 11 ≤5 C1 Class B
The EN61800-3 standard requires that the following warning be provided for drive
systems that do not comply with category C1 specifications:
This product can produce high-frequency interference emissions that may necessitate
targeted interference suppression measures in a residential or office environment.
2.9.2 Line harmonics requirements
The product is a device for professional applications as defined by EN 61000-3-2. The
following generic standards apply when establishing a connection to the public
power grid:
▪EN 61000-3-2
for symmetric, three-phase devices (professional devices with a total power of up
to 1kW)
▪EN 61000-3-12
for devices with a phase current of between 16A and 75A and professional
devices from 1kW up to a phase current of 16 A.
2.9.3 Interference immunity requirements
In general, the interference immunity requirements for a frequency inverter hinge on
the specific environment in which the inverter is installed.
The requirements for industrial environments are therefore higher than those for
residential and office environments.
The frequency inverter is designed such that the immunity requirements for
industrial environments and, thus, the lower-level requirements for residential and
office environments, are met and fulfilled.
The following relevant generic standards are used for the interference immunity test:

Design The fully automatic pressure booster system is equipped with vertical high-pressure
pumps (2) (all of which are speed-controlled) for pumping the fluid handled to the
consumer installations in the set pressure range.
Function Either two or three pumps (2) are controlled and monitored by motor-mounted
frequency inverters.
As the demand increases or decreases, pumps are started and stopped automatically.
As soon as the demand increases again after one pump has been stopped, another

5 Description
17 of 68
KSBDeltaSolo / KSBDeltaEco
pump which has not been in operation before is started up.
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; the actual pressure is measured by an analog pressure
measuring device (pressure transmitter).
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.
The use of variable speed pumps reduces wear as well as the frequency of pump
starts in parallel operation. If a duty pump fails, the next pump is started up
immediately. A fault is output, which can be reported via volt-free contacts (e.g. to
the control station).
If the demand drops towards 0, the pressure booster system slowly runs down to the
stop point.
As standard, one of the pumps is on stand-by. The control system defines each of the
pumps as stand-by pump in alternation. This prevents stagnation of water in any of
the pumps. Via a parameter in the control system the stand-by pump function can be
disabled in order to operate the system without stand-by function.
The pressure booster system is designed with integrated electronic dry running
protection.
A digital lack-of-water indicator can be connected to the corresponding contacts.
During commissioning and after every power failure, the pressure booster system fills
the piping system slowly, to prevent any damage to the piping by surge pressure.
5.6 Noise characteristics
Pressure booster systems are available with different numbers and sizes of pumps.
Therefore, the expected total sound pressure level in dB(A) needs to be calculated.
Refer to the pump's operating manual for the noise characteristics of the individual
pumps.
Calculation example:
Number of pumps Expected total sound pressure level
in dB(A)
Single pump . . . . . dB(A)
2 pumps, total +3 dB(A)
3 pumps, total +4,5 dB(A)
4 pumps, total +6 dB(A)
5 pumps, total +7 dB(A)
6 pumps, total +7,5 dB(A)
Example Single pump 48 dB(A)
4 pumps, total +6 dB(A)
54 dB(A)
The expected total sound pressure level of 54dB(A) for this configuration may
develop when all four pumps are running under full-load conditions.
Refer to the pumps' operating manual for the noise characteristics of the individual
pumps.

6 Installation at Site
6.1 Installation
Install pressure booster systems either in the technical equipment room or in a well-
ventilated, frost-free, lockable room used for no other purpose. No harmful gases are
allowed to enter the place of installation. An adequately sized floor drain (leading to
a sewer or equivalent) must be provided.
The pressure booster system is designed for a maximum ambient temperature of 0°C
to +40°C at a relative humidity of 50%.
NOTE
Do not install pressure booster systems next to sleeping or living quarters.
The anti-vibration mounting of the pressure booster system provides adequate
insulation against solid-borne noise. If expansion joints (KSB accessory) are used for
damping vibrations, their fatigue strength (endurance limit) must be given due
consideration. Expansion joints must be easily replaceable.
6.2 Checks to be carried out prior to installation
Place of installation
WARNING
Installation on mounting surfaces which are unsecured and cannot support the
load
Personal injury and damage to property!
▷Use a concrete of compressive strength class C12/15 which meets the
requirements of exposure class X0 to EN206-1.
▷The mounting surface must have set and must be completely horizontal and
even.
▷Observe the weights indicated.
NOTE
The anti-vibration mounts of the pressure booster system provide adequate
insulation against solid-borne noise.
Thanks to level-adjustable feet (KSB accessory) the pressure booster system can also
be installed in a horizontal position on uneven floors.
For pressure booster systems with Movitec 2, 4, 6, 10 and 15, level-adjustable feet are
available as accessories.
Check the structural requirements.
All structural work required must have been prepared in accordance with the
dimensions stated in the outline drawings.
6.3 Installing the pressure booster system
WARNING
Top-heavy pressure booster system
Risk of personal injury by pressure booster system tipping over!
▷Pressure booster systems awaiting final installation must be secured against
tipping over.
▷Firmly anchor the pressure booster system.

6 Installation at Site
20 of 68 KSBDeltaSolo / KSBDeltaEco
Remove all packaging before installing the pressure booster system. Connect the
pressure booster system's inlet line and discharge line to the corresponding site
distribution lines.
NOTE
In order to avoid transmission of piping forces onto the pressure booster system
and transmission of solid-borne noise, we recommend installing length-limited
expansion joints.
Allow sufficient space for maintenance and repair work.
üAll structural work required has been checked.
üThe dimensions of the concrete foundation are correct, and the concrete has set
firmly.
1. Mark out the anchoring holes on the floor as shown in the outline drawing.
2. Drill the holes (max. diameter: 12mm).
3. Insert plug fixings of appropriate size.
4. Set the pressure booster system down in its correct installation position.
5. Use suitable bolts to firmly anchor the pressure booster system.
6.4 Installing the piping
Make sure that piping is installed without transmitting any stresses or strains. The use
of length-limited expansion joints (see accessories) is recommended.
CAUTION
Air pockets in suction line
Pressure booster system cannot prime!
▷Lay piping with a continuously rising slope (as shown).
Suction lift operation
Incorrect Correct
NOTE
For suction lift operation install suitable swing check valves at the suction line ends
which are submerged in the fluid handled. Take into account the head losses
caused by these swing check valves.
Do not exceed the maximum suction lift of the pumps.
6.4.1 Fitting an expansion joint
DANGER
Sparks and radiant heat
Fire hazard!
▷Take suitable precautions to protect the expansion joint if any welding work is
carried out nearby.
