An earthquake can result in contact with the safety bearings. All forces occuring hereby
are safely absorbed by the properly installed flange connections.

Pfeiffer Vacuum centering rings with splinter shield or protection screen in the high vac-
uum flange protect the turbopump against foreign bodies coming from the chamber.
Thus, the pumping speed of the pump is reduced.
Splinter shield DN 200
Protection screen DN 200
Danger from the turbopump and vibration damper being torn-off
In case of sudden blocking of the rotor, an applied vibration damper cannot compensate
any of the occurring forces. There is a danger of the turbopump being torn-off and there-
by resulting severest injuries and property damages. Applicable safeguards must be
taken to compensate possible occurring torques.
 Definitely consult with Pfeiffer Vacuum.
 Do not exceed the max. permissible temperature at the vibration damper (100 °C).
When using dry backing pumps, Pfeiffer Vacuum HiPace pumps are designed for instal-
lation in any orientation.
 Support pipes in front of the vacuum pump or remove them. No force from the pipe
system may be exerted on the fixed pump.
