5.7 Aligning the pump and motor
After having installed the pump set and connected the piping, check the coupling
alignment and, if required, re-align the pump set (at the motor).

The coupling guard and the footboard for the coupling guard, if any, have been
removed.
1. Check the coupling alignment.
2. Unscrew the hexagon head bolts (1) at the motor and the locknuts (3) at the
baseplate.
3. Turn the levelling screws (2) by hand or by means of an open-jawed wrench
until the coupling alignment is correct and all motor feet rest squarely on the
baseplate.
4. Re-tighten the hexagon head bolts (1) at the motor and the locknuts (3) at the
baseplate.
5. Check that the coupling and shaft can easily be rotated by hand.
WARNING
Unprotected rotating coupling
Risk of injury by rotating shafts!
▷
Always operate the pump set with a coupling guard.
If the customer specifically requests not to include a coupling guard in KSB's
delivery, then the operator must supply one!
▷
Observe all relevant regulations for selecting a coupling guard.
DANGER
Risk of ignition by frictional sparks
Explosion hazard!
▷
Choose a coupling guard material that is non-sparking in the event of
mechanical contact (see DIN EN 13463-1).
6. Re-install the coupling guard and the footboard for the coupling guard, if any.
7. Check the distance between coupling and coupling guard.
The coupling and coupling guard must not come into contact.
5.7.2 Motors without levelling screw
Any differences in the centreline heights of the pump and motor shafts are
compensated by means of shims.
