Fore-Vacuum Pump Connection

A flange KF 40 NW is available to connect the Turbo-V 2300 TwisTorr
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 Turbo-V 2300 TwisTorr 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.

Connection C-Electrical

The turbopump is connected to the controller through an 8-pin
connector and a 6 pin connector.
8-pin connector
