Aligning Motor
CAUTION: The motor bracket must be aligned precisely to prevent damage
to the coupling and the pump.
For this reason, after assembly first check alignment at low speed (5 min‐
1
).
1. Line up the shafts of the motor and the pump and check whether the two
shafts are aligned vertically and horizontally. If necessary, loosen the
pump, adjust it, then tighten it crosswise with 25 Nm (220 lbin) torque.
For information on the coupling, refer to Important Regarding Coupling in
this section.
2. Attach the coupling to the pump shaft without using force (no jolts or
pounding). Torque: 36 Nm (320 lbin).
3. Insert the motor shaft (1, Fig. 7‐24) in the coupling such that the shaft
lines up with the first coupling element or protrudes no more than 1 to
2 mm (0.04 - 0.08 in).
4. The axial offset, meaning the sum of the four gaps (4, Fig. 7‐24), must
result in at least 2 mm (0.08 in) of air to accommodate the heat expansion
during operation.
Permitted radial offset: 1 mm (0.04 in)
Permitted angular offset: 1 °
5. Tighten the coupling screws (3, Fig. 7‐24). Torque: 36 Nm (320 lbin).
6. Attach the motor bracket with the aid of an angle on the melter chassis.

7. Tighten the motor bracket screws. Torque: 20 Nm (177 lbin).
