Fore-Vacuum Pump Connection

A flange KF 25 NW is available to connect the Special Turbo-V 1K-G
pump to the fore-vacuum pump. A hose or vacuum 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 bellows.
The Special Turbo-V 1K-G pump is characterized by its high compression ratio
NOTE
also for oil vapors. When using a mechanical oil-sealed pump, it is advisable to
install a suitable trap between the turbopump and the fore-vacuum pump in
order to prevent oil backstreaming.

Electrical Connection

Figure 38
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 and F are connected to the temperature sensor (NTC type, 30 KΩ
resistance at 25 °C) and pin E is connected to the pump ground; pins
G and H are not connected. If the temperature sensor is
disconnected, the pump will not start. To prevent damage to the
pump when the temperature exceeds 60 °C, the sensor automatically
cuts out the power supply.
