Usage limits of the vacuum pump
2.5 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 (F5) as lubricant.
► Use sealing gas as appropriate for the process.
► Operate the vacuum pump within the application limits of the product and in compliance with the
technical data.
► Adhere to the installation, commissioning, operating, and maintenance instructions.
► Use only accessory parts recommended by Pfeiffer Vacuum.
2.6 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:
● Transport, installation or operation of the vacuum pump in an impermissible spatial position
● Pumping media which are corrosive to materials of the vacuum pump
● Pumping explosive media
● Pumping radioactive media
● Pumping media prone to exothermic reactions
● Pumping media that introduce an ignition source to the suction chamber
● Pumping media that form adhesive deposits inside the suction chamber and cause the pistons to
touch or jam
● Pumping fluids - flushing media for cleaning are permissible
● Using the vacuum pump to generate pressure
● Using the vacuum pump in systems in which sporadic loads and vibrations or periodic forces act
on the unit
● Using the vacuum pump in potentially explosive atmospheres
● Using the vacuum pump in areas with strong electrical, magnetic or electromagnetic fields
● Use of the vacuum pump with open vacuum and/or fore-vacuum flange open to the atmosphere
● Using lubricants not specified by Pfeiffer Vacuum
● Lifting the vacuum pump without the prescribed eye bolts, for example on piping.
