Risks in the event of faults
WARNING
Danger of death due to the turbopump tearing off in the event of a fault
Sudden blocking of the rotor generates high destructive torques in accordance with ISO 27892. If it is
not
fastened correctly, the turbopump will tear off. The energy released in this way can propel the
entire pump or broken pieces from the inside of the pump through the room. Potentially dangerous
gases may escape. There is a risk of serious injury, potentially even fatal, and significant equipment
damage.
► Follow the installation instructions from the manufacturer.
► Observe the requirements for stability and the design of the counter flange.
► Only use approved original accessories or mounting elements approved by Pfeiffer Vacuum for
the installation process.
WARNING
Danger of death due to the turbopump with vibration damper is tearing off in the event of a
fault
Sudden blocking of the rotor generates high destructive torques in accordance with ISO 27892.
These result in the turbopump tearing off when using a vibration damper. The energy released in this
way can throw the entire pump or broken pieces from the inside of the pump through the space. Po-
tentially dangerous gases may escape. There is a risk of serious injury, potentially even fatal, and
significant property damage.
► Provide suitable safety measures on customer's side to compensate the torques arising.
► Please contact Pfeiffer Vacuum before installing a vibration damper.
