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

appropriate nameplate (and the respective EC Declaration of

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

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.

Safety notes

Safety chapter

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.
