WN 124-252 identifies the carbon vane used in a number of Becker DVX, KDX and KVX dry-running rotary vane pumps. VacAir supplies this vane under reference VA901401.
There are two Becker set part numbers for WN 124-252 because different pumps use different quantities of the same vane. 90140100004 is a set of 4 vanes, while 90140100007 is a set of 7 vanes.
Each new WN 124-252 carbon vane measures 170 × 37.4 × 4.3 mm. The vane height when new is 37.4 mm and the minimum wear height is 26 mm. What do the final digits of the Becker part number indicate? 90140100004 = 4 WN 124-252 vanes 90140100007 = 7 WN 124-252 vanes |

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.
