2.4 Connecting the MAG to
the vacuum chamber
The MAG is shipped in a sealed PE bag with desiccant.
Do not open the package until immediately before instal-
ling.
Do not remove the covers and blanking flanges until you
are ready to make the connections, to ensure that the
MAG is installed under the cleanest possible conditions.
Pay attention to maximum cleanliness when connecting.
Remove the transport seal from the intake flange. To do
so unscrew the screws (15/2) and remove the aluminum
cover. We recommend saving the transport seal for
maintenance.
Foreign objects entering the pump through the high-va-
cuum flange can cause serious damage to the rotor.
That’s why the splinter guard must always be installed.
Damages caused during operation without the splinter
guard are excluded from warranty.
Warning
The pump must be securely attached. If the
pump should suddenly seize, inadequate
attachment could cause the pump to break
away or allow internal pump parts to be dis-
charged. Never operate the pump (in bench
tests, for instance) without its being con-
nected at the vacuum chamber.
If the pump should suddenly seize, the dec-
celeration torque of 30,000 to 65,000 Nm
will have to be absorbed by the system. To
accomplish this, use all bolts provided by
Leybold for fastening the high-vacuum flan-
ge; see one of the Fig. 16 to 24.
Mount the MAG as close as possible to the vacuum
chamber. If the MAG is permanently flanged to a vacu-
um chamber with a weight exceeding 500 kg, it will not
be necessary to secure it in any other way.
The vacuum chamber must be securely attached to the
floor or a solid wall.
In case of lighter vacuum vessels secure the pump addi-
tionally. The pump’s bottom is equipped with tappered
holes for fastening a support; see dimensional drawing.
