SCREWLINE Vacuum Pumps for Pumping Pure Oxygen

Cologne, Germany 2007-03-07

The dry compressing SCREWLINE screw type vacuum pumps are a true alternative for utmost

reliability and safety. Special versions of these pumps are now available for processes involving

increased quantities of oxygen up to 100 percent. The SCREWLINE O2 pump versions attain a

higher level of operational safety. During production and assembly of certain processes, freedom

from hydrocarbons must be ensured widely so as to prevent a self-ignition of organic materials

like oils, greases, and sealing materials when being exposed to increased oxygen

concentrations.

For this reason, only selected materials are used in the manufacture of the SCREWLINE vacuum

pumps qualified for oxygen applications, and the manufacturing process is subject to special

quality assurance measures. In this way it is ensured that the SCREWLINE vacuum pumps can

be employed for the evacuation of gases containing oxygen concentrations of over 21% or even

for pumping of pure oxygen.

As O2 versions, these pumps are equipped as standard with the SCREWLINE monitoring system

and a seal gas monitoring unit. As add-on components, an exhaust silencer and a RUVAC Roots

pump adapter are available. With the RUVAC Roots pumps which are also qualified for pumping

oxygen, complete pump systems can be built.

Further typical areas of application for SCREWLINE O2 pumps can be found for example, in filling

systems for oxygen cylinders, in plasma cleaning, in space technology and research, as well as

in the area of coating technology. Today, commonly oil-sealed pumps using expensive PFPE oil

as the sealant and lubricant are used in these applications. Through the dry compressing

SCREWLINE O2 pumps, the customers can expect a significant savings potential.
