Becker carbon vanes can often be identified from the WN reference marked on the edge of the original vane. This provides a useful way of confirming the replacement required when servicing a dry-running rotary vane pump.
This vane is identified as WN 124-205 and is used across a number of Becker DTLF and VTLF pump models. Depending on the particular pump, a complete replacement set contains either 8 or 10 vanes.
The WN 124-205 carbon vane measures 220 × 88 × 6 mm. Because several Becker OEM references are associated with this vane, the pump model should be checked against the compatibility information below before ordering. Searching for Becker WN 124-205 or 901373 vanes? VacAir supplies WN 124-205 replacement carbon vanes under our reference VA901373. Use the model table below to identify the correct Becker part number and set quantity for your pump. |

The carbon vanes in a dry-running rotary vane pump wear progressively during operation. Measuring their height during routine servicing provides a simple way of assessing the remaining vane life.
When checking WN 124-205 vanes, it is also good practice to inspect the surrounding pump components and operating condition:
✓ Rotor and rotor shaft condition
✓ Cylinder bore condition
✓ Bearings
✓ Inlet filter condition
✓ Relief valve operation
✓ Carbon dust, contamination or signs of excessive heat
A new WN 124-205 vane has a height of 88 mm. The minimum wear height is 60 mm. Vanes at or below 60 mm should be replaced as a complete set using the correct quantity for the pump model.

Checking vane height during servicing helps identify when replacement is required.
