Risks in the event of malfunctions
WARNING
Danger to life from the turbopump breaking away in the event of a fault
Sudden jamming of the rotor generates high destructive torques in accordance with ISO 27892. If the
turbopump is
not
properly secured, it can shear off. The energy that this would release could throw
the entire turbopump or shattered pieces from its interior through the surrounding space. Potentially
dangerous gases can escape. There is a risk of very serious injuries, including death, and extensive
property damage.
► Follow the installation instructions for this turbopump.
► Observe the requirements regarding stability and design of the counter flange.
► Use only original accessories or fixing material approved by Pfeiffer Vacuum for the installation.
WARNING
Risk of injury caused by the turbopump breaking away with the vibration compensator in the
event of a malfunction
Sudden jamming of the rotor generates high destructive torques in accordance with ISO 27892.
When using a vibration compensator, this will probably lead to the turbopump being sheared off in
use. The energy that this would release could throw the entire turbopump or shattered pieces from its
interior through the surrounding space. Potentially dangerous gases can escape. There is a risk of
very serious injuries, including death, and extensive property damage.
► Take suitable safety precautions on-site for the compensation of the occurring torques.
► Before installing a vibration compensator, you must first of all contact Pfeiffer Vacuum.
WARNING
Danger to life from poisoning where toxic process media leak from damaged connections
Sudden twisting of the turbopump in the event of a fault causes fittings to accelerate. There is the risk
of damaging on-site connections (e.g., fore-vacuum line) and resulting leaks. This results in leakage
of process media. In processes involving toxic media, there is a risk of injury and danger to life due to
poisoning.
► Keep masses connected to the turbopump as low as possible.
► Use flexible lines to connect to the turbopump where necessary.
WARNING
Health hazard through poisoning from toxic contaminated components or devices
Toxic process media result in contamination of devices or parts of them. During maintenance work,
there is a risk to health from contact with these poisonous substances. Illegal disposal of toxic sub-
stances causes environmental damage.
► Take suitable safety precautions and prevent health hazards or environmental pollution by toxic
process media.
► Decontaminate affected parts before carrying out maintenance work.
► Wear protective equipment.
