Caution!
Dry running of the mechanical seal when checking the direction of rotation.
► Fill and vent the pump before checking the direction of rotation.
► Make sure that the flushing system (with double mechanical seal) flushes
the mechanical seal.
► Switch on the motor only briefly (1-2 seconds), check the direction of
rotation and correct if necessary.
6.2 Special personnel qualification
The personnel used for setup, installation and connection must be adequately
qualified for this work. See also Section 2.6, Page 15.
6.3 Setup, installation, and connection
6.3.1 Checking smooth running of the rotors
Before installation, check that the rotors are running smoothly.
Perform the following steps:
1.
Remove the motor shroud (only for SUPER version).
2.
Remove the coupling guard.
3.
Carefully rotate the shaft of the coupling.
The shaft must be rotatable without the rotors rubbing. If a rotor rubs against
something, it has some damage that may have happened during transport of
the pump.
If the rotors rub: Contact the GEA Hilge service.
If the rotors rotate freely:
4.
Reattach the coupling guard.
5.
Reattach the motor shroud (only for SUPER version).
→ The rotator has been checked for running smoothly.
