WARNING!
Warning of dangerous or unknown feed chemical
Should a dangerous or unknown feed chemical be used: It
may escape from the hydraulic components 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.
CAUTION!
Warning of feed chemical spraying around
Feed chemical can spray out of the hydraulic components 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 unauthor‐
ised persons.
– Depressurise the system before commencing any work
on hydraulic parts.
Cause
The wrong mains voltage or no
mains voltage is connected.
Cause
The operating diaphragm of the
metering diaphragm has ruptured.
WARNING!
Warning of escaping feed chemical
When metering critical or combustible feed chemicals or in
hazardous locations, under no circumstances must the
second diaphragm also rupture.
– If the pump membrane rupture sensor triggers, stop the
pump immediately and only restart once a new multi-
layer safety diaphragm is fitted.
Remedy
The specified mains voltage can
be found on the nameplate.
Remedy
