IDENTIFYING BECKER VANE WN 124-220
|
Becker replacement vanes can often be identified from the WN code marked on the original vane. Matching this code with the pump model helps confirm that the correct replacement set has been selected.
WN 124-220 is used in the Becker DT 4.8 pressure pump and VT 4.8 vacuum pump. Both models require a complete set of 5 carbon vanes, corresponding with Becker OEM reference 90138800005.
A new WN 124-220 vane measures 41 × 18 × 3 mm. The new vane height is 18 mm, with a minimum wear height of 12.5 mm. Looking for Becker WN 124-220 or 90138800005 vanes? VacAir supplies WN 124-220 replacement carbon vanes under our reference VA901388 for both the Becker DT 4.8 and VT 4.8. |

WHEN SHOULD WN 124-220 VANES BE REPLACED?
|
Vanes are normal wearing components in dry-running rotary vane pumps. Their height gradually reduces during operation, so checking vane dimensions during routine maintenance provides a straightforward indication of remaining service life.
When inspecting WN 124-220 vanes, it is also sensible to check the general condition of the pump and components that can influence vane life:
✓ Check all five vanes for consistent wear
✓ Inspect rotor slots for contamination or damage
✓ Examine the cylinder and internal running surfaces
✓ Check the inlet filter and cooling airflow
✓ Inspect bearings for excessive play or noise
✓ Look for excessive dust, heat or unusual wear patterns
A new WN 124-220 vane has a height of 18 mm. The minimum wear height is 12.5 mm. Vanes at or below 12.5 mm should be replaced as a complete set of five.

Regular vane measurement helps identify when the replacement limit has been reached.
