Becker WN124-243 Vanes 90141200007

IDENTIFYING BECKER VANE WN 124-243

The vane identification code is a useful way of confirming the correct replacement set for a Becker dry-running rotary vane pump. Where possible, the vane code should be checked together with the pump model and part-number reference.
WN 124-243 vanes are fitted to Becker DX 4.16 and VX 4.16 pumps. The latest Becker reference is 90141200007. The same vane set may also be identified by the earlier/alternative reference 90139600007.

A new WN 124-243 vane has a height of 34 mm. The minimum permissible wear height is 21 mm. Each pump requires a complete set of 7 vanes.

Searching for 90141200007 or 90139600007 Becker vanes?

Both references identify the WN 124-243 vane set used in the Becker DX 4.16 and VX 4.16. VacAir lists the latest 90141200007 reference as the primary part number while retaining 90139600007 for cross-reference and identification.

CHECKING WN 124-243 VANE WEAR

Carbon vanes gradually reduce in height as part of normal pump operation. Measuring them during servicing allows vane wear to be assessed before the minimum permissible height is reached.
When servicing a DX 4.16 or VX 4.16, the complete vane set and associated pump components should be inspected:
✓ Measure all seven vanes and compare their wear
✓ Check that the vanes move freely within the rotor slots
✓ Inspect internal running surfaces for scoring or damage
✓ Check filters and cooling airflow
✓ Inspect bearings for noise, play or deterioration
✓ Investigate abnormal carbon dust or uneven vane wear
A new WN 124-243 vane has a height of 34 mm. The minimum wear height is 21 mm. Once the vanes reach 21 mm, the complete set of seven should be replaced.
