2.1 Operating environment

When using the
TURBOVAC
magnetic induction at the pump housing surface may not
exceed the following values:
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 of 2500 Nm will have to be absorbed by the
system. To accomplish this, 10 clamping bolts are requi-
red when securing an ISO-K type high-vacuum flange.
Clamping bolts made of steel must be torqued down to
35 Nm, those made of stainless steel to 50 Nm.
You will find the order numbers for the (clamping) bolts
in the Leybold Catalog.
The clamping bolts are not included as standard equip-
ment with the pump.
