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.

Connection C - ELECTRICAL

The turbopump is connected to the controller
through an 8-pin connector. Pins B, C and D are
the 3-phase supply to the motor, pins A, F and G
are connected to the temperature sensors (NTC
type, 30 KΩ resistance at 20° C) and pin E is con-
nected to the pump ground; pin H is not connected.
If the temperature sensors are disconnected, the
pump will not start. To prevent damage to the
pump when the temperature exceeds 60° C, the
sensors automatically cut out the power supply.
