§
Only use tools and lifting gear that are approved for use in potentially
explosive atmospheres.
Handling of hazardous media Upon breakage of the diaphragm and/or leaks, the transferred medium
mixes with the air in the surroundings and/or in the pump housing. Make
sure that a dangerous situation cannot arise as a result.
When pumping hazardous media, observe the safety regulations for the
handling of said media.
Handling of combustible media Make certain that the temperature of the medium is always sufficiently be-
low the ignition temperature of the medium so as to prevent ignition or ex-
plosion. This also applies for abnormal operating situations.
Note that the temperature of the medium increases when the pump com-
presses the medium.
Therefore, make certain that the temperature of the medium also remains
sufficiently below the ignition temperature of the medium even when it is
compressed to the maximum permissible operating pressure of the pump.
The maximum permissible operating pressure of the pump is stated in
Chapter
.
Make certain that the permissible ambient temperature (
is not exceeded.
Where applicable, also take into account external energy sources (such as
radiated heat sources) that could additionally heat the medium.
In case of doubt, contact KNF Customer Service.
Environmental protection Protect all replacement parts in storage according to environmental regula-
tions and dispose of all replacement parts according to regulations. Ob-
serve both the respective national and international regulations here. This
applies in particular to parts that are contaminated with toxic substances.
EU/EC directives/standards See EC/EU Declaration of Conformity
