7.7.7.1 Checking the lubricant reservoir for leakage
After reassembly, the mechanical seal area/lubricant reservoir must be checked for
leakage. The leak test is performed at the lubricant filler opening.
Observe the following values for leak testing:
▪ Test medium: compressed air
▪ Test pressure: 1 bar maximum
▪
Test duration: 5 minutes

Symbol Description
FD
Always apply a liquid sealant (e.g. Hylomar SQ32M) to sealing surfaces
marked with this symbol.
1. Undo screw plug 903.03 and joint ring 411.03 of the lubricant reservoir.
2. Screw the testing device tightly into the G 1/2 plug thread.
3. Carry out the leak test with the values specified above.
ð
The pressure must not drop during the test period.
ð If the pressure does drop, check the sealing elements and screwed
connections.
4. Repeat the leak test if required.
5. If the leak test has been successful, remove the testing device. Apply a thread-
locking agent to the screw plug and screw it back in together with a new joint
ring.
6. Fill in lubricant. ( ð Section 7.4.1.4, Page 59)
7.7.7.2 Checking the leakage chamber for leakage
After reassembly, the mechanical seal area/lubricant reservoir must be checked for
leakage. The leak test is performed at the lubricant filler opening.
Observe the following values for leak testing:
▪
Test medium: compressed air
▪ Test pressure: 0.8 bar maximum
▪ Test duration: 2 minutes
▪ Opening: hole of screw plug 903.02
