Becker WN124-220 Vanes 90138800005

IDENTIFYING BECKER VANE WN 124-220

BECKER PUMP COMPATIBILITY

WN 124-220 vanes are fitted to the following Becker DT and VT dry-running rotary vane pumps. Both applications use Becker reference 90138800005 and require 5 vanes per pump.

REPLACING BECKER WN 124-220 CARBON VANES

VacAir Superstore stocks and supplies Becker WN 124-220 replacement carbon vanes for the Becker DT 4.8 pressure pump and VT 4.8 vacuum pump. Although these two pumps serve different applications, both use the same carbon vane specification and require a complete set of five vanes. Keeping the vanes within their specified wear limit is an important part of maintaining dependable pump performance.

A new WN 124-220 carbon vane measures 41 × 18 × 3 mm, with an original vane height of 18 mm. The specified minimum wear height is 12.5 mm. During routine servicing, measure the remaining height of each vane and examine the running edges for cracks, chipped corners, uneven wear or damage. Vanes that have reached or fallen below the specified wear limit should be replaced.

The complete five-vane replacement set corresponds to Becker OEM part number 90138800005. VacAir supplies this specification under reference VA901388. The vane identification may be written as WN 124-220 or WN124-220. Both designations refer to the same replacement vane family.

For the DT 4.8, vane condition can influence the pump’s ability to deliver the required pressure for its intended application. In the VT 4.8, worn vanes may affect vacuum performance. If either pump is showing reduced output, unusual noise, excessive carbon dust or signs of overheating, the vanes should be inspected alongside the other mechanical and service components rather than assuming that worn carbon is the only possible cause.

Replacing all five vanes as a matched set avoids combining new carbon components with vanes that have already experienced significant wear. Before installing replacements, check that the rotor slots are clean, the cylinder running surface is in suitable condition and the vanes can move freely. Investigating the cause of abnormal wear can help prevent repeated failures and unnecessary production downtime.

WN 124-220 maintenance inspection checklist:

CORRECT CARBON VANE ORIENTATION Before installing Becker WN 124-220 replacement carbon vanes, carefully clean the rotor slots and remove carbon dust, debris or fragments from the previous set. Each new vane must slide freely within its slot without binding. Check the full length of each slot and inspect the rotor for damage that could restrict vane 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 actual vane profile, direction of rotation and manufacturer’s fitting instructions for the particular pump before installation. The Becker DT 4.8 pressure pump and VT 4.8 vacuum pump both require five WN 124-220 vanes. Fit the complete matched set and inspect the cylinder, rotor shaft and bearings before reassembly. If the previous vanes have worn unevenly or fractured, establish the reason before returning the pump to service. Always follow the relevant Becker manufacturer’s maintenance and fitting instructions. VacAir’s experienced engineers can assist with replacement vane identification, professional fitting, pump servicing, fault diagnosis and mechanical repairs where required.
