Connection A - HIGH VACUUM FLANGE

To connect the Turbo-V551/701 pump to the ISO
inlet flange, remove the outer ring and position the
centering ring as shown in the figure.
Then fix the two flanges with the clamps or claws
as shown in the figure.

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. Repeat
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.
