2 Safety chapter
The following signal words are used in these operating instructions
to denote different severities of danger:
Signal word Meaning
WARNING Denotes a possibly dangerous
situation. If this is disregarded,
you are in a life-threatening sit‐
uation and this can result in
serious injuries.
CAUTION Denotes a possibly dangerous
situation. If this is disregarded,
it could result in slight or minor
injuries or material damage.
The following warning signs are used in these operating instruc‐
tions to denote different types of danger:
Warning signs Type of danger
Warning – hand injuries.
Warning – high-voltage.
Warning – danger zone.
nOnly use the pump to meter liquid metering chemicals.
nIn potentially explosive atmospheres in zone 1, device category
II 2G, explosion group II C, only operate the pump with the

Conformity) for pumps for use in areas at risk of explosion in
compliance with Directive 94/9/EC in accordance with the
European guidelines. The explosion group, category and
degree of protection specified on the label should correspond
to or be better than the conditions given in the intended field of
application.
nOnly start up the pump after it has been correctly installed and
commissioned in accordance with the technical data and speci‐
fications contained in the operating instructions.
nObserve the general limitations with regard to viscosity limits,
chemical resistance and density - see also ProMinent Resist‐
ance List (in the Product Catalogue or at
www.prominent.com/en/downloads)!
nAll other uses or modifications are prohibited.
nNever operate pumps without the relevant nameplate (and the
respective EC Declaration of Conformity) for pumps for use in
atmospheres at risk from explosion in atmospheres potentially
at risk from explosion.
nThe pump is not intended for the metering of gaseous media or
solids.

Explanation of the terms:
Technical personnel
A qualified employee is deemed to be a person who is able to
assess the tasks assigned to him and recognise possible dangers
based on his/her technical training, knowledge and experience, as
well as knowledge of pertinent regulations.
Note:
A qualification of equal validity to a technical qualification can also
be gained by several years employment in the relevant work area.
Electrical technician
Qualification of personnel
Safety chapter
7

Electrical technicians are deemed to be people, who are able to
complete work on electrical systems and recognise and avoid pos‐
sible dangers independently based on their technical training and
experience, as well as knowledge of pertinent standards and regu‐
lations.
Electrical technicians should be specifically trained for the working
environment in which they are employed and know the relevant
standards and regulations.
Electrical technicians must comply with the provisions of the appli‐
cable statutory directives on accident prevention.
Instructed person
An instructed person is deemed to be a person who has been
instructed and, if required, trained in the tasks assigned to him/her
and possible dangers that could result from improper behaviour, as
well as having been instructed in the required protective equipment
and protective measures.
Customer Service
Customer Service department refers to service technicians, who
have received proven training and have been authorised by ProMi‐
nent or ProMaqua to work on the system.
CAUTION!
These operating instructions include notes and
quotes from German guidelines relating to the
system operator's scope of responsibility. This
information does not discharge the operator from
his responsibility as an operator and is intended
only to remind him or make him aware of specific
problem areas. This information does not lay claim
to being complete, nor applicable to every country
and every type of application, nor to being uncon‐
ditionally up-to-date.

WARNING!
– Observe the European Operator Directive
99/92/EC (ATEX 137), implemented in Ger‐
many by the Industrial Health and Safety Reg‐
ulation and the German Ordinance on Haz‐
ardous Substances, for the installation and
operation of equipment in areas at risk from
explosion.
– Observe the European standards EN 1127-1,
EN 60079-10, EN 60079-14, EN 60079-17 and
EN 60079-25 and EN 50039 for inherently safe
electrical circuits. (In Germany these standards
are partly implemented by VDE 0165 and VDE
0118).
–Adhere to the respective national regulations
outside of the EU.
– Ensure that installations in areas at risk from
explosion are checked by a "recognisably
trained" skilled operative. This applies specifi‐
cally to intrinsically safe electrical circuits.
– The following information relates essentially to
the unique characteristics in areas at risk from
explosion but does not replace the standard
operating instructions.
– Only clean plastic parts carefully with a damp
cloth to avoid electrostatic charges and sparks.
WARNING!
Warning of dangerous or unknown feed chemical
Should a dangerous or unknown feed chemical be
used: It may escape from the hydraulic compo‐
nents when working on the pump.
– Take appropriate protective measures before
working on the pump (e.g. safety glasses,
safety gloves, ...). Observe the safety data
sheet for the feed chemical.
– Drain and flush the liquid end before working
on the pump.
WARNING!
Danger from hazardous substances!
Possible consequence: Fatal or very serious inju‐
ries.
Please ensure when handling hazardous sub‐
stances that you have read the latest safety data
sheets provided by the manufacture of the haz‐
ardous substance. The actions required are
described in the safety data sheet. Check the
safety data sheet regularly and replace, if neces‐
sary, as the hazard potential of a substance can be
re-evaluated at any time based on new findings.
The system operator is responsible for ensuring
that these safety data sheets are available and that
they are kept up to date, as well as for producing
an associated hazard assessment for the worksta‐
tions affected.
Safety chapter

CAUTION!
Warning of feed chemical spraying around
Feed chemical can spray out of the hydraulic com‐
ponents if they are manipulated or opened due to
pressure in the liquid end and adjacent parts of the
system.
– Disconnect the pump from the mains power
supply and ensure that it cannot be switched
on again by unauthorised persons.
– Depressurise the system before commencing
any work on hydraulic parts.
CAUTION!
Warning of feed chemical spraying around
An unsuitable feed chemical can damage the parts
of the pump contacted by the chemical.
– Take into account the resistance of the mate‐
rials which will come into contact with the
chemical when selecting the feed chemical -
see the ProMinent Product Catalogue or visit
www.prominent.com/en/downloads.
CAUTION!
Danger of personnel injury and material damage
The use of untested third party parts can result in
personnel injuries and material damage.
– Only fit parts to metering pumps, which have
been tested and recommended by ProMinent.
CAUTION!
Danger from incorrectly operated or inadequately
maintained pumps
Danger can arise from a poorly accessible pump
due to incorrect operation and poor maintenance.
– Ensure that the pump is accessible at all times.
– Adhere to the maintenance intervals.
In the event of an electrical accident, disconnect the mains cable
from the mains or press the emergency cut-off switch fitted on the
side of the system!
If feed chemical escapes, also depressurise the hydraulic system
around the pump as necessary. Adhere to the safety data sheet for
the feed chemical.
