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!
Warning of feed chemical spraying around
An unsuitable feed chemical may cause premature wear
to the pump hose.
– Observe the pump hose's resistance and "Chemical
Resistance List DFXa" available at www.promi‐
nent.com when selecting the feed chemical.
CAUTION!
Warning of feed chemical spraying around
Pumps which are not fully installed hydraulically can
eject feed chemicals from the outlet openings of the dis‐
charge valves as soon as they are connected to the
mains.
– The pump must first be hydraulically installed and
then electrically.
– In the event that you have failed to do so, press the
[STOP/START] button or press the emergency-stop
switch.
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!
Danger of injury to personnel and material damage
The use of untested third party components can result in
injury to personnel and material damage.
– Only fit parts to metering pumps that have been
tested and recommended by ProMinent.
