Safety information
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.
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.
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.
