Pump Fixing
WARNING!
Failure to comply with these installation instructions could result in the pump
detaching from the system in the event of a rotor failure, which could cause
property damage or serious injury or death.
The TwisTorr 404 FS can be installed in any position. Fix the
TwisTorr 404 FS in a stable position, mounting the inlet flange of the
turbopump to the system counter-flange, with a connection capable
of withstanding a torque of 25000 Nm around its axis.
WARNING!
For safety reasons, it is recommended to use only flexible connections
between the foreline and vent of the pump and the rest of the system.
ISO-K flange can be secured by means of high-resistance steel clamps,
class 12.9 (Agilent IC 63250 DCMZ type).
The following table shows, for each flange, the necessary number of
IC63250DCMZ clamps and the relevant fixing torque.
