CHECKING WN 124-252 VANE WEAR
|
Carbon vanes gradually reduce in height during normal dry-running operation. Measuring the vanes during servicing allows their remaining usable height to be compared with the specified wear limit.
When checking WN 124-252 vanes:
✓ Measure the height of every vane in the set
✓ Inspect vane faces and edges for damage or cracking
✓ Check that the vanes slide correctly in the rotor slots
✓ Look for uneven wear across the complete vane set
✓ Check filters and cooling arrangements during servicing
✓ Investigate abnormal carbon dust or internal scoring
New WN 124-252 vane height: 37.4 mm.
Minimum wear height: 26 mm.Once the vanes have reached the minimum height, replace the complete set – either 4 vanes or 7 vanes according to the pump model. |
Measure vane height and inspect condition during routine pump maintenance.
