Checking the WN code on the existing carbon vane is a useful way of confirming the correct replacement set. For positive identification, the vane code should be considered together with the Becker pump model and part-number reference.
WN 124-246 vanes are fitted to Becker DX 4.10 and VX 4.10 dry-running rotary vane pumps. The current Becker reference is 90141300007, superseding the previous part number 90139800007.
A new WN 124-246 vane measures 55 × 26 × 3 mm. The new vane height is 26 mm, and the minimum wear height is 18 mm. The replacement set contains 7 carbon vanes. Searching for 90141300007 or 90139800007 Becker vanes? Both part numbers relate to the WN 124-246 vane used in Becker DX 4.10 and VX 4.10 pumps. VacAir lists 90141300007 as the current reference while retaining 90139800007 to help customers cross-reference older parts and documentation. |

The carbon vanes in a dry-running rotary vane pump are designed to wear gradually during operation. Their height should therefore be checked during servicing so that the set can be replaced before the minimum permissible dimension is reached.
When inspecting a DX 4.10 or VX 4.10, it is also sensible to check the surrounding pump components and operating condition:
✓ Measure all seven vanes and compare their condition
✓ Confirm the vanes move freely within the rotor slots
✓ Inspect the internal running surfaces for scoring or damage
✓ Check inlet filters and cooling airflow
✓ Check bearings for excessive noise, play or deterioration
✓ Investigate unusual carbon dust or uneven vane wear
A new WN 124-246 vane has a height of 26 mm. The minimum wear height is 18 mm. Once the vanes reach 18 mm, the complete set of seven should be replaced.

Check vane height during routine servicing and compare the measurement with the specified wear limit.
