WARNING!
It is mandatory that you read the safety information and
specifications in the "Storage, Transport and Unpacking"
chapter prior to shipping the pump.
WARNING!
Fire hazard with flammable media

oxygen.
– The pump may not work if there is a mixture of feed
chemical with oxygen in the liquid end. A specialist
may need to take appropriate actions (using inert
gas, ...).
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.
Third-party spare parts for the pumps may result in prob‐
lems when pumping.
Only use original spare parts.
