Original Becker carbon vanes are commonly marked WN 124-120 on the vane edge. This marking can therefore be particularly useful when identifying a replacement vane removed from a pump.
WN 124-120 is a 63 × 36 × 4 mm carbon graphite vane used in a range of Becker DT, T and VT dry-running rotary vane pumps.
Becker OEM reference 90134700007 is a set of seven WN 124-120 vanes for the compatible Becker pump models listed on this page.
Check the vane dimensions and compatible pump models below. If you are unsure whether this is the correct vane for your Becker pump, contact VacAir with your 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 124-120 vanes, it is 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.
