Flexible Coupling; Check Winding Element Coupling Arrangement -H - Landustrie LANDY BTP62-40 Operation & Maintenance Manual

7.6 Flexible coupling:

Between motor and pump a flexible coupling is used to absorb vibrations and misalignment.
Also the dismounting of the bearing housing or motor will become easy.
(Not applicable for version -K).
For maintenance and renewal of elastomers version -H, see 7.6.1 and 7.6.2.
For version -V see 7.6.3 and 7.6.4
When working on the pump make sure it cannot start unexpectedly !
Inspection of flexible couplings arrangement "H"
Is your installation equipped with a "Winding element" coupling,
then go to paragraph 7.6.1
Is your installation equipped with a "Spider" coupling,
then go to paragraph 7.6.3
7.6.1 Check winding element coupling arrangement –H:
-1. The radial deviation (R) max 0.4mm.
-2. Radial deflection (R)max. 0.4mm.
-3. Angular deflection (A) max. 1
To correct the alignment, use skims underneath the motor and pump fixing bolts.
Re-install the spacer, elastomers, rings and protecting hood.
The pump is now ready to use.

Subject to modifications
- Remove the protective cover from the coupling.
- Check that the spacer (4) has no play
compared to the solid parts (1)
- Remove both mounting pieces (pos 2) by
unscrewing the fastening screws.
- Remove the rubber elements (3) and check for
wear. If the metal parts (1) and (4)
need to be replaced, continue with
chapter 7.6.2.
- Check that the shaft ends of the pump and motor
are in Line up with each other by a row on the
two fixed coupling parts (1). Do this on both
the top and on the side of the coupling.
