Installation and operating instructions Wilo-Rexa NORM 21
INSTALLATION English
Alignment hydraulics/motor and coupling
checking
The pump has been aligned at the factory. During
transportation or installation, however, there may
be impairments. For the pump to run properly, the
alignment of the hydraulics/motor and the coup-
ling must be checked and adjusted if necessary.
NOTICE
The hydraulics are fixed by the connection to
the pipeline system. Therefore, the motor must
always be aligned with the hydraulics!

4 Lamellae package
5 Measuring point
1. Dismantle coupling guard
- Loosen the screws of the floor plate on the
coupling guard and remove the floor plate.
- Loosen the screws of the coupling guard on
the baseplate and remove the coupling guard
upwards.
2. For checking, the distance between the coupling
connections on the motor and hydraulics side
must be measured.
The measured values must not exceed or fall
below the following values!
Permissible distances

S
1max
11 mm (0.43 in) 10.7 mm (0.42 in) 11.3 mm (0.44 in)
3. If the measured values are out of tolerance, the
coupling must be removed, the motor realigned,
and the coupling reinstalled.
4. Install the coupling guard
- Place the coupling guard from above over the
coupling on the baseplate and fasten it to the
baseplate with 4 screws.
- Insert the floor plate into the coupling guard
from below and fasten it to the coupling guard
with the screws.

1. Dismantle coupling guard.
2. Dismantle coupling spacer » see instructions
from manufacturer
3. Install attachment points on the motor » see
instructions from manufacturer
4. Fasten the lifting equipment to the attachment
points.
5. Loosen the motor fixation on the baseplate.
6. Slowly raise the motor by 1-2 mm (0.04-0.08 in).
7. Place alignment plate underneath
8. Drain motor
9. Check alignment.
10. Reattach the motor to the baseplate and disman-
tle the attachment points.
11. Reinstall the coupling spacer and align it correctly
» see instructions from the manufacturer
12. Install the coupling guard.
5.5. Install the motor (if supplied separately)
CAUTION! Centre of gravity extension!
The motor can be installed before the pump.
In this case, there is a centre of gravity exten-
sion of the entire unit. The attached centre of
gravity marker is then no longer valid. Mate-
rial damage may occur due to the unit tipping
over. Do not install the motor until the pump
has been mounted at the installation site.

Depending on the size, the motor may be supp-
lied separately. In this case, the motor must be
installed on the baseplate on-site.
1. Dismantle coupling guard
- Loosen the screws of the floor plate on the
coupling guard and remove the floor plate.
- Loosen the screws of the coupling guard on
the baseplate and remove the coupling guard
upwards.
2. Attach the lifting equipment to the attachment
points on the motor » see instructions from
manufacturer
3. Lift the motor and position it over the baseplate
4. Align the motor with the motor mounting and
lower it slowly.
5. Check the alignment of the motor to the pump
with a straight edge. Max. deviation: 0.1 mm
(0.04 in).
6. If the deviation is greater, the motor must be
aligned with the pump using alignment plates or
levelling screws.
7. If the alignment is correct, fix the motor to the
baseplate with the fastening screws.
8. Remove the lifting equipment and dismantle the
attachment points from the motor. Keep the
attachment points on the pump for dismantling
the motor later.
