Connecting Fore-Vacuum Side; Fig. 14: Flange Connection Cf-F, Stud Screw And Tapped Hole; Fig. 15: Flange Connection Cf-F, Stud Screw And Through Hole - Pfeiffer Vacuum HiPace 800 Operating Instructions Manual

Fig. 14:
Connection of the stud screw and tapped hole
1. For the connection of the turbopump, use only the approved mounting kits from Pfeiffer Vacuum.
2. Screw in the required number of stud screws with the shorter end in the holes on the counter
3. If used: Insert the protective screen or splinter shield with clamping lugs downwards in the turbo-
4. Place the seal exactly in the hollow.
5. Connect the flange with the components of the mounting kit according to the figure.
6. Tighten the screw couplings all the way around.
7. Then check the torque, since flowing of the sealing material may make it necessary to re-tighten

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.
