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. Improper use is any, even unin-
tended, use, which is contrary to the product purpose; and 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 of 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
● Use of the vacuum pump in potentially explosive atmospheres
● Use of 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.
