NOTE:
The axial deviation of the two coupling halves may be a max. of
0.1 mm in every state, i.e. even at the operating temperature and
when inlet pressure is applied.
• When correctly aligned, connect the coupling halves and mount the
coupling protection. The tightening torques of the coupling are listed
in Tab. 6.
Tightening torques for set screws and coupling halves
(see also Fig. 15 and Fig. 16 ):

Alignment of the pump unit
All deviations in the measuring results indicate a misalignment. In this
case, the unit must be realigned to the motor.
• To do this, loosen the hexagon head bolts and the counter nuts on the
motor.
• Place shims under the motor feet until the height difference is com-
pensated. Pay attention to the axial alignment of the coupling.
• Tighten the hexagon head bolts again.
• Finally, check the function of the coupling and shaft. The coupling
and shaft must be easy to turn by hand.
• After correct alignment, mount the coupling protection.
