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.
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.
Delta p
Pressure difference between start-up pressure
and stop pressure. The value of delta p depends
on the number of pump stages and is
permanently stored in the control unit.
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.
Noise characteristics
The noise emission to be expected, indicated as
sound pressure level LpA in dB(A)

4.4 Design details
Design
The system consists of two non-self-priming single-stage centrifugal pumps with
suction and discharge side shut-off valves. The shut-off valves enable dismantling of
the pumps or check valves without taking the entire system out of service or draining
the piping system. The check valves (connection types C and V only) on the discharge
side prevent backflow through the pumps during standstill and reduce the load on
the mechanical seals.
An accumulator, a pressure transmitter and a pressure gauge are fitted on the
discharge side of the system.
The control cabinet is mounted on the system baseplate and ready-wired to the
system.

5 Baseplate
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 pressure + 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:

requirements are met:
▪The system has been properly connected to the electric power supply and is
equipped with all protection devices.
▪All relevant VDE standards and/or regulations applicable in the country of use are
complied with.
▪The dry running protection device has been installed.
CAUTION
Dry running of pump
Damage to the pump/pressure booster system!
▷If no dry running protection device is connected when commissioning takes
place, pressure booster systems in manual or test run mode will be stopped
automatically after approx. 10 seconds. If the dry running protection terminal is
disabled by means of a bridge, the operator shall assume responsibility for any
dry running that might occur.
NOTE
The water company and the fire department must be informed in due time prior to
commissioning/test running the system.
6.1.2 Dry running protection
Pressure booster systems can be factory-equipped with pressure switches as dry
running protection devices. Such dry running protection devices will be factory-set to
the inlet pressure values specified in the purchase order.
If the factory settings should not match the site data, set the start and stop pressure
as described in the operating manual of the pressure switch.
