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 304 FS can be installed in any position. Fix the
TwisTorr 304 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 1000 Nm around its axis.
The ISO-K flange can be fixed using high strength steel clamps (like
Agilent model IC63250DCMZ).
The following table shows, for each flange, the necessary number of
IC63250DCMZ clamps and the relevant fixing torque.
FLANGE FIXING DEVICE N. FIXING TORQUE
ISO 100 K M10 clamps 4 22 Nm
ISO 160 K M10 clamps 4 22 Nm
The turbopump with ConFlat inlet flange must be fixed to the
vacuum chamber by means of the appropriate Agilent hardware. See
the appendix "Technical Information" for a detailed description.
NOTE
The TwisTorr 304 FS cannot be fixed by means of its base.
