IDENTIFYING BECKER VANE WN 124-205

BECKER PUMP COMPATIBILITY

Becker WN 124-205 vanes are fitted to the following DTLF and VTLF dry-running rotary vane pumps. The OEM reference reflects the quantity and application, so check both the pump model and set quantity when identifying the correct replacement.

REPLACING BECKER WN 124-205 CARBON VANES

VacAir Superstore stocks and supplies Becker WN 124-205 replacement carbon vanes for compatible DTLF and VTLF dry-running rotary vane pumps. These large carbon graphite vanes are used in industrial equipment where dependable vacuum or pressure performance is important. Regular inspection and replacement at the appropriate wear limit help protect the pump and reduce the risk of an unexpected production stoppage.

A new WN 124-205 carbon vane measures 220 × 88 × 6 mm, with an original height of 88 mm. The specified minimum wear height is 60 mm. Each vane should be measured individually during servicing and examined for cracks, chipped corners, uneven wear or signs of overheating. Any significant difference in wear across the set should be investigated before replacement vanes are fitted.

Correct vane quantity is particularly important for WN 124-205. Although the carbon vane dimensions are the same, the Becker DTLF and VTLF pump families listed on this page use different quantities depending on the model. The DTLF 2.400, DTLF 2.500, VTLF 2.400 and VTLF 2.500 require eight vanes, corresponding to Becker OEM reference 90137301008. The DTLF 400, DTLF 500, VTLF 400 and VTLF 500 require ten vanes, corresponding to Becker OEM reference 90137301010.

When requesting replacement vanes, provide the complete pump model and, where necessary, its serial-number information. This helps ensure that the correct eight-vane or ten-vane set is supplied. The WN marking identifies the vane family, but it does not by itself establish the quantity needed for every compatible pump.

Replacing the complete matched set is normally preferable to combining new carbon vanes with partially worn components. If the previous set has suffered breakage, excessive dust generation or abnormal wear, inspect the pump’s internal components before installing replacements. A damaged cylinder, restricted rotor slot or worn bearing can cause further problems even when new carbon vanes have been fitted.

WN 124-205 maintenance inspection checklist:

CORRECT CARBON VANE ORIENTATION Before installing Becker WN 124-205 replacement carbon vanes, thoroughly clean the rotor slots and remove accumulated carbon dust or fragments from the previous set. Inspect each slot for damage and confirm that the new vanes can move freely without binding. Restricted vane movement can affect pump operation and contribute to premature wear. The higher edge of the vane is the leading edge. The chamfer follows behind the leading edge, as illustrated in the adjacent VacAir fitting diagram. Confirm the vane profile and the correct orientation for the particular pump’s direction of rotation before installation. Fit the correct complete set for the pump model: eight vanes for DTLF/VTLF 2.400 and 2.500 models, or ten vanes for DTLF/VTLF 400 and 500 models. Check the rotor, cylinder running surface, shaft and bearings before fitting new carbon. If previous vanes have fractured or worn unevenly, investigate the cause rather than simply installing replacements. Always follow the relevant Becker manufacturer’s maintenance and fitting instructions. VacAir’s experienced engineers can assist with vane identification, professional fitting, pump inspection, servicing and mechanical repairs where required.
