Connection configurations
Connection B - FORE-VACUUM PUMP
A flange KF 40 NW is available to connect the Tur-
bopump to the fore-vacuum pump. A hose or vac-
uum approved pipe can be used. If a rigid pipe is
used, any vibration generated by the mechanical
pump must be eliminated through the use of bel-
lows.
NOTE
The Turbo pump is characterized by its high com-
pression ratio also for oil vapors. When using a
mechanical oil-sealed pump, it is advisable to in-
stall a suitable trap between the turbopump and the
fore-vacuum pump in order to prevent oil back-
streaming.
Then fix the two flanges with the clamps or claws
as shown in the figure.
