• Check the inlet and outlet of the pump and its oil condi-
tion, if there is a danger of forming deposits inside the
pump, e.g., in the pump unit of the rotary vane pump or
in the pump chamber of the diaphragm pump. Inspect
the pump regularly and clean if necessary.
• Install a cold trap in front of the pump if pumping ag-
gressive or corrosive gases or vapors.
• Consider interactions and chemical reactions of
the pumped media. Ensure that the materials of the
pump’s wetted parts are compatible with the pumped
substances, see section “Technical data”, pg. 19.
When changing the substances pumped, we recom-
mend purging the pump with air or inert gas prior to
changing the pumped media. Purging the pump will
pump out residues and it will reduce the possibility of
reactions of the pumped substances with each other
and with the pump’s materials.
Safety during operation
➨
Adopt suitable measures to prevent the release of dan-
gerous, toxic, explosive, corrosive, noxious or pollut-
ing fluids, vapors and gases. To prevent any emission
of such substances from the pump outlet, install an
appropriate collecting and disposal system and take
protective action for pump and environment.
➨
You must take suitable precautions to prevent any for-
mation of explosive mixtures in the expansion cham-
ber, in the oil reservoir, in the pump chamber of the
diaphragm pump, or at the outlet of the pump. In case,
e.g., of a diaphragm failure, mechanically generated
sparks, hot surfaces or static electricity may ignite
these mixtures. Use inert gas for gas ballast or vent-
ing, if necessary.
➨
Drain appropriately or otherwise remove any poten-
