WARNING
Unprotected rotating parts
Risk of personal injury!
▷ Do not touch rotating parts.
▷
When the pump is running, perform any work with utmost caution.
The leakage can be reduced.
1. Tighten the nuts on the gland follower by 1/6 turn.
2. Monitor the leakage for another five minutes.
Excessive leakage:
Repeat steps 1 and 2 until the minimum value has been reached.
Not enough leakage:
Slightly loosen the nuts at the gland follower.
No leakage:
Immediately switch off pump set!
Loosen the gland follower and repeat commissioning.
Checking the leakage
After the leakage has been adjusted, monitor the leakage for about two hours at
maximum fluid temperature.
Check that enough leakage occurs at the gland packing at minimum fluid pressure.
6.1.7 Shutdown
CAUTION
Heat build-up inside the pump
Damage to the shaft seal!
▷
Depending on the type of installation, the pump set requires sufficient after-
run time – with the heat source switched off – until the fluid handled has
cooled down.
CAUTION
Backflow of fluid handled is not permitted
Motor or winding damage! Mechanical seal damage!
▷
Close the shut-off elements.
ü The shut-off element in the suction line is and remains open.
1. Close the shut-off element in the discharge line.
2. Switch off the motor and make sure the pump set runs down smoothly to a
standstill.
NOTE
If the discharge line is equipped with a non-return or check valve, the shut-off
element may remain open provided that the system conditions and system
regulations are considered and observed.
For prolonged shutdown periods:
1. Close the shut-off element in the suction line.
2. Close any auxiliary lines.
If the fluid to be handled is fed in under vacuum, also supply the shaft seal with
barrier fluid during standstill.
