Hazards due to different substances
Pumping different substances or media can cause the substances
to react with one another.
Working materials which get into the vacuum pump with the gas
flow can damage the vacuum pump. Hazardous substances can
be deposited in the vacuum pump.
Possible protective measures, depending on the application:
>
Purge the vacuum pump with inert gas or air before changing
the medium to be pumped.
>
Use inert gas to dilute critical mixtures.
>
Prevent the release of hazardous, toxic, explosive, corrosive
fluids, gases or vapors or those that are harmful to health or
the environment, for example, through suitable laboratory facil ‑
ities with a fume hood and ventilation control.
>
Protect the inside of the vacuum pump from deposits or mois‑
ture, e. g, through the provision of a gas ballast.
>
Be aware of interactions and possible chemical reactions of
the pumped media.
>
Check the compatibility of the pumped substances with the
wetted materials of the vacuum pump.
