2.1 Operating environment

When using the
TURBOVAC
magnetic induction at the pump housing surface may not
exceed the following values:
50: B = 7 mT
TURBOVAC
151 – 1000:
TURBOVAC
B = 5 mT in case of radial impingement
B = 15 mT in case of axial impingement
Provide suitable shielding measures if these values are
exceeded.
The standard version is resistant to radiation at levels up
3
to 10 Gy.

2.2 Connecting the pump to
the vacuum chamber
Remove the packing flange from the high-vacuum
flange. Pay attention to maintaining maximum clean-
liness during connection work.
Warning
The high-vacuum flange must be securely
attached to the vacuum chamber . If the
pump were to become blocked, insufficient
attachment could cause the pump to break
away from its mount or allow internal pump
parts to be discharged. Never operate the
pump (in bench tests, for instance) without
its being flanged to the vacuum chamber.
If the pump should suddenly seize, the ensuing deceler-
ation torque will have to be absorbed by the system. To
accomplish this, the following are required when secur-
ing an ISO-K type high-vacuum flange:
