Original Becker carbon vanes are commonly marked WN 124-034 on the vane edge. This marking can therefore be particularly useful when identifying a replacement vane removed from a pump.
WN 124-034 is a 170 × 39 × 4 mm carbon graphite vane used in a range of Becker DVT, KDT and KVT dry-running rotary vane pumps.
The Becker 901330-series references shown on this page relate to different quantities of the same WN 124-034 vane. The quantity required depends on the Becker pump model. Looking for WN 124-034 or a Becker 901330-series vane? Check the vane dimensions and compatible pump models below. If you are unsure which quantity or reference is required, contact VacAir with your Becker pump model. |

Many maintenance engineers and factory service departments replace Becker carbon vanes in-house as part of routine vacuum pump servicing.
When replacing WN 124-034 vanes, check the pump model to ensure the correct quantity is fitted. It is also good practice to inspect the pump for other signs of wear or damage, including:
✓ Rotor and rotor shaft condition
✓ Cylinder body condition
✓ Bearings
✓ Inlet filter
✓ Relief valve operation
✓ Signs of overheating or contamination inside the pump
Replacing worn vanes without correcting the underlying cause of abnormal wear may reduce vane life and result in continued pump performance problems.
