☞ The diameter of the inlet and outlet pipeline should be at the least as large as the
diameter of the pump connection pipelines.
To the best of our knowledge the equipment is in compliance with the requirements of
the applicable EC-directives and harmonized standards (see “Declaration of conform-
ity”) with regard to design, type and model, especially directive IEC 1010. This directive
gives in detail conditions, under which the equipment can be operated safely (see also
IP degree of protection).
☞ Adopt suitable measures in case of differences, e. g. using the equipment outdoors,
installation in altitudes of more than 1000 m above mean sea level, conductive
pollution or dewiness.
Pay attention to symbol ”hot surfaces” on the equipment.
☞ Adopt suitable measures to prevent any danger arising from the formation of hot
surfaces or electric sparks.
The pumps have no approval for operation in or for pumping of potentially ex-
plosive atmospheres.
If pumping different substances, purge the pump with inert gas prior to changing the
pumped media in order to pump out residues and to avoid reactions of the pumped
substances with each other with and the pump material. Ensure that the materials of
the wetted parts are compatible with the pumped substances, see section ”Technical
data”.
Take into consideration interactions and chemical reactions of the pumped media.
The pumps are not suitable for pumping substances which may form deposits inside
the pump.
☞ If there is a danger of the formation of deposits in the pump chamber (check inlet
and outlet of the pump) inspect the pump chamber regularly and clean if necessary.
The pumps are not suitable to pump unstable substances and substances which
react explosively under impact (mechanical stress) and/or when being exposed to
elevated temperatures without air.
The pumps are not suitable to pump self inflammable substances, substances which
are inflammable without air and explosive substances.
The pumps are not suitable for pumping dust and have no approval for operation
below ground.
Ensure that the materials of the wetted parts are compatible with the pumped
substances, see section ”Technical data”.
☞ Adopt suitable measures to prevent the release of dangerous, explosive, corrosive
or polluting fluids.
☞ Use inert gas for gas ballast if necessary.
☞ The user must take suitable precautions to prevent any formation of explosive
mixtures in the expansion chamber or at the outlet. In case of e.g. a diaphragm
crack, mechanically generated sparks, hot surfaces or static electricity may ignite
these mixtures.
☞ Take adequate precautions to protect people from the effects of dangerous sub-
stances (chemicals, thermal decomposition products of fluoroelastomers), wear
appropriate safety-clothing and safety glasses.
☞ Comply with applicable regulations when disposing of chemicals. Take into consid-
eration that chemicals may be polluted.
The motor is shut down by a thermal cutout in the winding.
☞ Manual reset is necessary. Switch off the pump or isolate the equipment from mains.
Wait approx. five minutes before restarting the pump.
☞ Avoid high heat supply (e. g. due to hot process gases).
☞ Ensure sufficient air admittance if pump is installed in a housing.
