Connection A – HIGH VACUUM FLANGE
For ISO-K flange connections, fix the two flanges
with the clamps as shown in the figure.
WARNING!
It is mandatory to connect the pump in such a way
to withstand the torque specified in the "IN-
STRUCTION FOR USE" section. Specifically pay
attention to clamp design, material of clamps and
bolts and bolt fixing torque.
Connection configurations
For ConFlat flange connections we recommend
using Varian hardware.
To facilitate assembly and dismantling, apply Fel-
pro C-100 high temperature lubricant to the screw
threads protruding from the flange and between
the nuts and flange.
Note that the connections can be made only with
the bolt in the lower side.
Attach the units and tighten each one in turn. Re-
peat the sequential tightening until the flange faces
meet.
Exercise care when tightening nuts and bolts to
avoid creating dents in the envelope as this may
cause the pump rotor to lock.
