Pulsation Damper with Separating Diaphragm
810.1
Operating Instructions
EN
Before commissioning and during operation of the pulsation damper the respective regulations valid at the place of
installation are to be observed.
The European Directive 97/23/EC is valid in the European Union since 29/05/2002.
sera pulsation dampers are required if for procedural reasons, a pulsation-poor delivery rate is desired or, depen-
ding on the pipe geometry, unacceptable high pressure peaks are to be reduced when operating oscillating dis-
placement pumps. This can require the installation of pulsation dampers on the suction- and pressure side.

Operating Instructions
EN
Please read these operating instructions carefully before the pulsation damper is started or serviced. Observance
of these operating instructions and, in particular, the safety instructions, helps to:
■Avoid dangers to persons, machines, and environment.
■Increase reliability and service life of the pulsation damper and the complete system.
■Reduce repair cost and downtime.
The sera quality management and quality assurance system for pumps, systems, and ttings is certied according
to DIN EN ISO 9001.
sera products comply with the valid safety requirements and accident prevention regulations.
Always keep these operating instructions within reach at the place of instal-
lation!
ATTENTION!
Pay attention to the safety data sheet of the pumped medium! The owner
must take corresponding accident prevention measures to protect opera-
ting personnel from danger through the pumped media used!
CAUTION!
1.3 Marking of notes on the product
Symbols which are directly attached to the pulsation damper, e.g. symbols for uid connections are to be observed
and kept in legible condition.
1.4 Quality instructions
The safety instructions specied in these operating instructions, the national regulations concerning ac-cident pre-
vention as well as internal working-, operating-, and safety instructions of the owner are to be observed.
Inobservance of these safety instructions can result in danger to persons, hazards to the environment and damage
to the pulsation damper.
Inobservance can result in:
■Failure of important functions of the pulsation damper/system.
■Inobservance of prescribed methods for maintenance and servicing.
■Danger to persons through chemical inuences.
■Hazards to the environment through leaking dangerous media.

The following points are to be observed:
■In general, the pulsation damper is designed for uid group I, if nothing to the contrary is specied in the order
conrmation.
■The service life for special steel is ca. 20 years if the regular checks and maintenance intervals are kept. The
owner is responsible that the regular checks according to 97/23/EC are carried out.
sera - pulsation dampers are only to be deployed according to the intended purpose stated in the order conrma-
tion.
sera does not assume any responsibility for damage resulting from an operation which does not conform with the
intended use.
If the pulsation damper is to be used for other applications, then the suitability of the pulsation damper for the new
operating conditions must be discussed with sera beforehand!
Criteria for proper operation of the pulsation damper:
■Max. pressure of the pulsation damper.
■Observe characteristics of the pumped medium – uid group (please see safety- and product data sheet of the
pumped medium – the safety data sheet is to be provided by the supplier of the chemical).
■Resistance of the materials which come in contact with the pumped medium.
■Operating conditions at the place of installation.
■Temperature of the pumped medium.
■Sufcient volume when the pulsation damper is operated together with oscillating displacement pumps.
sera does not assume any responsibility if these criteria are not or only partly observed by the owner/operator.
Secure pulsation dampers by a safety tting which is set to the maximum
permissible pressure according to the valid regulations and the directive for
pressure equipment 97/23/EC.
CAUTION!
The national regulations for pressure vessels must be taken into account!
CAUTION!
The structural design of the pulsation dampers must not be changed!
ATTENTION!

Pulsation Damper with Separating Diaphragm
810.1
Operating Instructions
EN
The system operator may only approve persons to operate or maintain the unit, who are at least eighteen years old
and suitably qualied, and of a physical and mental state to perform the tasks entrusted to them. These persons
must be properly instructed and act responsibly, properly, and reliably. The operating personnel must be familiar
with all applicable accident prevention and safety instructions and regulations.
2.5 Approved installation-, maintenance and operating personnel
In order to avoid risks to health, the provisions of the German Ordinance on Hazardous Substances (GefStoffV)
(§14 Safety Data Sheet) and relevant national safety regulations for the pumped medium and the operating condi-
tions of the pulsation damper must strictly be adhered to.
Wear protective clothing, gloves, and a face protecting mask.
CAUTION!
Personal protective equipment must be provided by the owner!
NOTE!
2.6 Personal protection for maintenance and service
The maximum allowable pressure depends on the operating temperature and the pumped medium. It must not be
exceeded. This is applicable to normal operation as well as lling from the sera pressure measuring- and lling
equipment.
Do not exceed the maximum allowable pressure!
ATTENTION!
For pulsation dampers the permissible pressures according to the operating
temperatures (please see Chapter „Technical specications“) are strictly to
be observed.
ATTENTION!

On delivery, immediately check the packaging for damage. Report any external damage immediately to the trans-
port company, and ll in a damage report. After the transport company has recorded the damage, open the package
and check the contents for damage.
An undamaged packaging protects the unit during subsequent storage and should only be opened when the pul-
sation damper is installed.
Proper storage increases the service life of the pulsation damper and comprises prevention of negative inuences
such as heat, humidity, dust, chemicals etc.
The following storage instructions are to be observed:
■Storage place: cool, dry, dust-free and slightly ventilated
■Storage temperatures between +2°C and +40°C
■Relative air humidity not more than 50%.
If these values are exceeded, metal products should be sealed in foil and protected from condensation water with
a suitable desiccant.
Do not store solvents, fuels, lubricants, chemicals, acids, disinfectants and similar in the storage room.

7Allowable minimum / maximum temperature
During operation of oscillating displacement pumps, pressure
peaks occur. The magnitude of these peaks depends, among
other things, on the pipe length and diameter as well as on the
density of the pumped medium.
Depending on the system conguration, these pressure peaks
may lead to cavitation on the suction side.
On the pressure side, also either excess supply or inadmissibly
high loads on the system may occur.
Pulsation dampers reduce these pressure peaks and provide for
a pulsation-poor ow after the pulsation damper.
With the pulsation dampers described in these instructions, the
conveying medium is separated from the gas cushion (1) by a
diaphragm (2) (pulsation damper with separating diaphragm).
This helps to prevent that the gas is carried away by the pumped
medium (3) during operation. The chamber above the diaphragm
must be precharged with oil-free air or nitrogen to a value of ap-
prox. 60% of the operating pressure to be expected (gas prech-
arge pressure).
The damper can only work pro-
perly if the gas cushion is large
enough. For this reason, always
ensure that this condition is met!
