Operation conditions
The devices have no approval for operation in or
for pumping of potentially explosive atmospheres.
The devices 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,
- self inammable substances,
- substances which are inammable without air and
- explosive substance
The devices have no approval for operation below
ground.
+ The devices are not suitable for suction of dust.
Take into consideration interactions and chemical
reactions of used media.
Ensure that the materials of the wetted parts are com
patible with the pumped substances, see section ”Tech
nical data”.
Safety during operation
Adopt suitable measures to prevent the release of dan
gerous, toxic, explosive, corrosive, noxious or polluting
uids, vapors and gases. In such cases, install an ap
propriate collecting and disposal system and take pro
tective action for pump and environment.
If the equipment is used in combination with hazardous
materials (e. g., in medical-microbiological labora-
tories) check all relevant safety and health require
ments and determine the applicability of regulatory
limitations prior to use if necessary.
