Becker WN124-219 Vanes 90138700005

IDENTIFYING BECKER VANE WN 124-219

BECKER PUMP COMPATIBILITY

WN 124-219 replacement vanes are used in the following Becker DT and VT dry-running rotary vane pumps. All four models use Becker reference 90138700005 and require a complete set of 5 vanes.

REPLACING BECKER WN 124-219 CARBON VANES

VacAir Superstore stocks and supplies Becker WN 124-219 replacement carbon vanes for the DT 4.2, DT 4.4, VT 4.2 and VT 4.4 dry-running rotary vane pumps. These compact carbon graphite vanes are an important service component, helping the pump maintain its intended operation as the rotor turns. Regular inspection allows worn or damaged vanes to be identified before they contribute to reduced performance or an unexpected pump failure.

A new WN 124-219 vane measures 32 × 16 × 3 mm, with an original vane height of 16 mm. The specified minimum wear height is 11 mm. This leaves a relatively small absolute wear allowance, making accurate measurement important. During servicing, inspect the entire vane for cracks, chipped corners, uneven wear and signs of overheating rather than relying solely on the measured height.

The Becker DT 4.2, DT 4.4, VT 4.2 and VT 4.4 models listed on this page each require five WN 124-219 carbon vanes. The complete five-vane replacement set corresponds to Becker OEM part number 90138700005 and is supplied by VacAir under reference VA901387. We recommend replacing the complete matched set rather than combining new vanes with components that have already experienced significant wear.

Although these are small pump components, the condition of the surrounding rotor and cylinder remains important. Carbon dust, restricted rotor slots, poor inlet filtration or mechanical wear may shorten vane life. If the previous set has suffered premature wear or breakage, inspect the pump thoroughly before fitting new carbon to avoid repeating the same problem.

WN 124-219 maintenance inspection checklist:

CORRECT CARBON VANE ORIENTATION Before installing Becker WN 124-219 replacement carbon vanes, carefully clean the rotor slots and remove carbon dust or fragments from the previous set. Each replacement vane must move freely within its slot without binding. Because these vanes are only 32 mm long, even small deposits or damage within a slot may interfere with their movement. 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 correct orientation for the pump’s direction of rotation before installation. All four compatible Becker models require a complete five-vane set. Before fitting the new vanes, inspect the cylinder running surface, rotor, shaft and bearings. If the previous vanes have broken, worn unevenly or shown signs of overheating, investigate the cause before reassembling the pump. Always follow the relevant Becker manufacturer’s fitting and maintenance instructions. VacAir’s experienced engineers can provide guidance on vane identification, professional fitting, pump inspection and mechanical repairs where required.
