CAUTION
Improper mounting of elastomers
Elastomers' sealing function reduced!
▷
Never use elastomeric parts again which have been heated.
▷ As a general rule, always use new elastomeric parts.
Mount all coupling hubs which have not been fitted.
Make sure that the markings on all coupling components to be connected are
identical.
5.7.1 Checking the shaft ends for run-out
Fig. 11: Checking the shaft ends for run-out
NOTE
Observe the marking between coupling hub and shaft. ( ð Section 7.3.4, Page 82)
1. Permissible tolerance at the pump shaft ≤ 0.03 mm/ 0.0012 inch. If this value is
exceeded, inform KSB.
2. After every 90° turn, read measured values again.
3. Permissible tolerance at the motor shaft, see the data provided by the
manufacturer.
5.7.2 Fitting the coupling hubs (with key)
1. Carefully clean the shaft ends and bores of the coupling hubs and check them
for dimensional accuracy.
2. Slightly deburr the hub keyways and insert the key.
Fig. 12: Clearance between keyway and key
3. Check the protruding dimension of the key. Observe tolerance in accordance
with the figure "Clearance between keyway and key".
