Warning – danger zone.
nOnly use the pump to meter liquid feed chemicals.
nOnly use the pump after it has been correctly installed and started up
in accordance with the technical data and specifications contained in
the operating instructions.
nObserve the general limitations with regard to viscosity limits, chem‐
ical resistance and density - see also ProMinent® resistance list (In the
product equipment catalogue or at www.prominent.com !
nAll other uses or modifications are prohibited.
nThe pump is not intended for the metering of gaseous media and
solids.
nThe pump is not intended to meter extremely hazardous media or
media harmful to life.

WARNING!
Warning of hazardous feed chemical
Should a dangerous feed chemical be used: it may
escape from the hydraulic components when working on
the pump, material failure or incorrect handling of the
pump.
– Take appropriate protective measures before
working on the pump (e.g. safety glasses, safety
gloves, ...). Adhere to the material 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 injuries.
Please ensure when handling hazardous substances
that you have read the latest safety data sheets provided
by the manufacture of the hazardous substance. The
actions required are described in the safety data sheet.
Check the safety data sheet regularly and replace, if
necessary, 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 workstations affected.
WARNING!
Danger of electric shock
A mains voltage may exist inside the pump housing.
– If the pump housing has been damaged, you must
disconnect it from the mains immediately. It may
only be returned to service after an authorised
repair.
CAUTION!
Warning of feed chemical spraying around
Feed chemical can spray out of the hydraulic compo‐
nents 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 that come into contact with the chemical.
– Take into account the resistance of the wetted mate‐
rials and the ProMinent Resistance List when
selecting the feed chemical - see the ProMinent
Product Catalogue or visit ProMinent.

CAUTION!
Danger of personnel injury and material damage
The use of untested third party parts can result in per‐
sonnel 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 main‐
tained 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.
All isolating protective equipment must be installed for operation:
nDrive front cover
nMotor fan cowling
nMotor terminal box cover
nPlug (Pos. 9 in Fig. 6 in Chap. "Repair")
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.
Sound pressure level LpA < 70 dB according to EN ISO 20361

3 Carrying out repairs
WARNING!
Only return the metering pump for repair in a cleaned
state and with a flushed liquid end - refer to the chapter
"Decommissioning"!
Only return metering pumps with a completed Decon‐
tamination Declaration form. The Decontamination Dec‐
laration constitutes an integral part of an inspection /
repair order. A unit can only be inspected or repaired
when a Declaration of Decontamination Form is sub‐
mitted that has been completed correctly and in full by
an authorised and qualified person on behalf of the
pump operator.
The "Decontamination Declaration Form" can be found
at www.prominent.de.

CAUTION!
Warning of feed chemical spraying around
PTFE seals, which have already been used / com‐
pressed, can no longer reliably seal a hydraulic connec‐
tion.
– New, unused PTFE seals must always be used.
CAUTION!
Danger of personnel injury and material damage
The use of untested third party parts can result in per‐
sonnel injuries and material damage.
– Only fit parts to metering pumps, which have been
tested and recommended by ProMinent.

nIf necessary take protective measures.
nAdhere to the material safety data sheet for the feed chemical.
nEnsure that the system is at atmospheric pressure.
1. Empty the liquid end (turn the liquid end upside down and allow the
feed chemical to run out; flush out with a suitable medium; flush the
liquid end thoroughly when using hazardous feed chemicals!)
2. Turn the stroke adjustment dial as far as 0% stroke length when the
pump is running (the drive axle is then difficult to turn).
3. Switch off the pump and secure it to prevent it being switched on
again.
4. Unscrew the hydraulic connectors on the discharge and suction
side.
5. Remove the screws.
