2.7 Foreseeable improper use
Improper use of the product invalidates all warranty and liability claims. Any use that is counter to the
purpose of the product, whether intentional or unintentional, is regarded as improper use; in particular:
● pumping media which are corrosive to or too aggressive for the vacuum pump materials
● pumping media that introduce an ignition source to the suction chamber
● pumping pyrophoric or corrosive media, or media releasing FKM
● pumping media prone to spontaneous, specific exothermic reactions
● pumping media that contain impurities such as particles, dust, or condensate
● pumping media that can condense or cause adhering deposits to form in the suction chamber
● pumping media with a propensity to sublimation
● pumping pressurized media (> atmospheric pressure)
● pumping fluids
● pumping radioactive media
● using the vacuum pump outside the specified area of application
● using the vacuum pump in systems in which sporadic loads and vibrations or periodic forces act
on the unit
● using the vacuum pump in strong electrical, magnetic, or electromagnetic fields
● using for media being pumped for which the ignition temperature drops below a temperature limit
of T4, at pressures greater than atmospheric pressure
● using pipes to lift the vacuum pump
● using accessories or spare parts not listed in this manual
● using the vacuum pump as a climbing aid
● painting the vacuum pump, motor and accessories
● using operating fluids that have not been approved by Pfeiffer Vacuum
● using mineral-based operating fluids such as P3, with an oxygen concentration > 21 %.
Mineral-based operating fluids are combustible and ignite at high temperatures, and when they
come into contact with pure oxygen. These operating fluids oxidize heavily and thus lose their lu-
bricating capacity.
