DANGER
Risk of potentially explosive atmosphere by incompatible fluids mixing in the
auxiliary piping
Risk of burns!
Explosion hazard!
▷ Make sure that the barrier fluid or quench liquid are compatible with the fluid
handled.
DANGER
Shaft seal failure caused by insufficient lubrication
Hot or toxic fluid could escape!
Damage to the pump!
▷
Before starting up the pump set, vent the pump and suction line and prime
both with the fluid to be handled.
CAUTION
Increased wear due to dry running
Damage to the pump set!
▷
Never operate the pump set without liquid fill.
▷ Never close the shut-off element in the suction line and/or supply line during
pump operation.
1. Vent the pump and suction line and prime both with the fluid to be handled.
Connection 6D can be used for venting (see drawing of auxiliary connections).
2. Fully open the shut-off element in the suction line.
3. Fully open all auxiliary feed lines (barrier fluid, flushing liquid, etc.), if any.
4. Open the shut-off element, if any, in the vacuum balance line and close the
vacuum-tight shut-off element, if any. ( ð Section 5.4.3, Page 25)
NOTE
For design-inherent reasons some unfilled volume in the hydraulic system cannot be
excluded after the pump has been primed for commissioning/start-up. However,
once the motor is started up the pumping effect will immediately fill this volume
with the fluid handled.
6.1.4 Final check
1. Remove the coupling guard and its footboard, if any.
2. Check the coupling alignment; re-align the coupling, if required.

Section 5.6, Page 27)
3. Check proper functioning of coupling/shaft.
Check that coupling/shaft can be easily rotated by hand.
4. Fit the coupling guard and its footboard, if any.
5. Check the distance between coupling and coupling guard.
The coupling guard must not touch the coupling.
