1. Equip the pump cover (53) with an O-ring (54) .
2. Unscrew the forcing screws (52) . The forcing screws should
be flush with the inside wall of the pump cover.
3. Slide the pump cover onto the pump casing (55) .
4. Screw the pump cover onto the pump casing with nuts (51) .
See the following table for the tightening torques:
10.10 Shaft Bearing Replacement
► Contact Fristam .
10.11 Coupling Replacement
► Use only couplings that have been approved by Fristam . The
coupling must conform to the characteristic of the pump. If
you have any queries, contact
Fristam .
Procedure
1. Turn off the motor and prevent it from being able to be
turned on accidentally.
2. Remove the coupling guard.
3. Loosen the gear motor from the base frame or the founda-
tion and remove.
4. Loosen the coupling according to the coupling manufactur-
er's specifications.
5. Dispose of the old coupling parts in an environmentally
friendly manner.
6. Mount new coupling parts on the pump shaft and the motor
shaft.
7. Place the pump on the base frame or the foundation so that
the pump shaft can be connected to the motor shaft with
the coupling.
8. Screw the pump loosely onto the base frame or the founda-
tion.
9. Check the parallel and angular misalignment of the shafts.
Fig. 38 Parallel misalignment
Fig. 39 Angular misalignment
10. Minimize deviations from the angular and parallel misalign-
ment. Realign or shim the shafts if necessary.
11. Screw the pump and gear motor to the base frame or the
foundation.
12. Fasten the coupling according to the coupling manufactur-
er's specifications.
13. Mount the coupling guard.
10.12 Gear Motor Replacement
Coupling
The coupling installation manual can be found in the supplier
documentation.
NOTICE
Gear Motor Oversized
Use of an incorrectly sized gear motor can result in serious dam-
age to the pump unit.
► Only replace the gear motor with one with the same rating;
see motor supplier documentation.
Procedure
1. Turn off the gear motor and prevent it from being able to be
turned on accidentally.
2. Remove the coupling guard.
3. Loosen the coupling according to the coupling manufactur-
er's specifications and remove.
4. Take the coupling parts off of the gear motor.
5. Detach the old gear motor from the base frame or the foun-
dation.
6. Dispose of the old gear motor. (see Chapter 2.7, "Disposal,"
page 7 ).
7. Remove protective coatings and grease from all coupling
parts.
8. Mount the coupling parts on the pump shaft and the motor
shaft.
9. Place the replacement motor on the base frame or the foun-
dation and fasten.
10. Continue as described in "Check the parallel and angular mis-
alignment of the shafts" in Chapter 10.11, "Coupling Replace-
ment," page 25, starting with step 9.
