Limits of use of the product
2.6 Proper use
► Use the vacuum pump for vacuum generation only.
► When pumping media with an oxygen concentration level of ≥ 21 %, only use perfluorinated, syn-
thetic oils (F4, F5, A113) as operating fluid.
► Adhere to the installation, commissioning, operating, and maintenance instructions.
► Do not use any accessory parts other than those recommended by Pfeiffer Vacuum.
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 of corrosive media (exception: C version of the rotary vane vacuum pumps)
● Pumping radioactive media
● Pumping of gases that introduce an ignition source to the suction chamber
● Pumping of gases that contain impurities such as particles, dust, or condensate
● Pumping explosive media
● Pumping of media with a propensity to sublimation
● Pumping of fluids
● Use of the vacuum pump in potentially explosive atmospheres
● Use of the vacuum pump outside the specified area of application
● Use for pressure generation
● Use in strong electrical, magnetic, or electromagnetic fields
● Connection to vacuum pumps or equipment which are not suitable for this purpose according to
their operating instructions
● Connection to devices with exposed live parts
● Use of accessories or spare parts not listed in these instructions
● Use of operating fluids other than those specified by Pfeiffer Vacuum
● Use of D1 or mineral oil as operating fluid with an oxygen concentration level of > 21%.
Mineral oils are combustible and ignite at high temperatures and when they come into contact with
pure oxygen. These oils oxidize heavily and thus lose their lubricating capacity.
