Technical Information
Connection of the Fore-Vacuum Pump
Connection of the Fore-Vacuum Pump
A flange KF 25 NW is available to connect the Turbo-V 750/850
TwisTorr Pumping System 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 750/850 TwisTorr Pumping System is characterized by its high
NOTE
compression ratio also for oil vapors. When using a mechanical oil-sealed pump,
it is advisable to install a suitable trap be-tween the turbopump and the fore-
vacuum pump in order to prevent oil backstreaming.
