Safety

At the same time, note that the temperature of the medium
rises as the pump compresses 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 permis-
sible operating pressure of the vacuum system. The maxi-
mum permissible operating pressure of the vacuum system is
given in Chapter 4 Technical data [} 13].
Make certain that the permissible ambient temperature (see 4
Technical data [} 13]) is not exceeded.
Where applicable, also take into account external energy
sources (such as radiated heat sources) that might heat the
medium further.
In case of doubt, contact KNF Customer Service.
3.6 Use
3.6.1 Foreseeable misuse
The pumps must not be operated in explosive atmospheres.
The pumps are not suitable for transferring the following:
§
Dusts
§
Liquids
§
Aerosols
§
Biological and microbiological substances
§
Fuels
§
Fibers
§
Oxidizing agents
§
Foodstuffs.
As standard, the pumps must not be used for simultaneous
generation of a vacuum and positive pressure.
No overpressure may be applied to the suction side of the
pump.
The pump must not be used if reactive explosive, or otherwise
dangerous mixtures can occur (e.g. with the medium) when
the gas ballast valve of the pump is open.
