3.2 Conforming Utilisation
The RUVAC pumps are vacuum pumps which in connection with suitable
backing pumps are capable of pumping gases and vapours.
They are employed to increase the pumping speed of backing pumps below
10-100 mbar by a very significant factor or for the purpose of attaining a
lower ultimate pressure.
Accessories which have not been specified by Leybold may only be used
after approval by Leybold.
3.2.1 Non-conforming Utilisation
Non-conforming utilisations for the pump are among others:
■
Pumping of gases and vapours for which the materials of the pump are not
suited.
■
Pumping of condensable vapours without adequately controlling the tem-
perature of the pump. Upon compression in the pump, these vapours may
condense or form deposits.
■
Pumping of dusts and solids without suitable screens and filters
■
Pumping of liquids
■
Pumping of ignitable gas mixtures
■
Operation at an impermissibly high differential pressures
■
Pumping of process gases which form hard or sticky deposits which may
cause the pump to seize.
■
The use of pump and frequency converter in the explosion hazard areas
■
Non-compliance with the described maintenance and service intervals.
■
Use in systems and pump systems in which the pressure may increase
over 1.2 bar abs.
■
Operation with an inadequately affixed pump.
■
Operation without suitable backing pump.
■
Operation at impermissibly high gas temperatures
■
Use in systems where pump, frequency converter and cables are sub-
jected to impact stresses.
■
Operation on movable systems or system components (locks or mobile
pump systems).
■
Use of pump, fitted ad-on components, drive electronics, flanges and
cables to climb onto the system.
■
Removing, covering or obstructing warning notices.
■
Standstill or storing of pump and drive electronics without suitable sealing
and drying. When stored in a humid atmosphere corrosion can occur.
■
Conversions, manipulations and maintenance work by persons not authori-
sed by Leybold.
