Check the gland packing during commissioning. Adjust the gland packing, if
required.
The gland packing must leak slightly during operation.
Prior to commissioning
1. Only lightly tighten the nuts of the gland follower by hand.
2. Use a feeler gauge to verify that the gland follower is mounted centred and at a
right angle to the shaft.
ð The gland must leak after the pump has been primed.
After five minutes of
operation
The leakage can be reduced.
1. Tighten the nuts of 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:
Switch off the pump set immediately!
Loosen the gland follower and repeat start-up.
Checking for 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 at minimum inlet pressure.
