Becker WN124-243 Vanes 90141200007, 90139600007

IDENTIFYING BECKER VANE WN 124-243

BECKER PUMP COMPATIBILITY

WN 124-243 replacement vanes are used in the Becker DX 4.16 and VX 4.16 dry-running rotary vane pumps. The current Becker part number is 90141200007, with 90139600007 retained as an alternative reference. Both pumps require 7 vanes.

REPLACING BECKER WN 124-243 CARBON VANES

VacAir Superstore stocks and supplies Becker WN 124-243 replacement carbon vanes for the DX 4.16 and VX 4.16 dry-running rotary vane pumps. These replacement vanes are supplied under VacAir reference VA901412 and correspond to the current Becker OEM part number 90141200007. The earlier or alternative Becker reference 90139600007 identifies the same vane set, making both numbers useful when sourcing replacements for existing equipment.

A new WN 124-243 carbon vane has a height of 34 mm, with a specified minimum wear height of 21 mm. During operation, carbon vanes gradually wear against the cylinder running surface. Measuring their remaining height during routine maintenance helps establish when replacement is necessary. Vanes at or below the 21 mm limit should be replaced, and any cracks, chipped edges or abnormal wear patterns should also be investigated.

Both the Becker DX 4.16 and VX 4.16 require a complete set of seven WN 124-243 carbon vanes. Although the pump models differ, the replacement vane specification and quantity are the same. We recommend changing all seven vanes together rather than combining new carbon vanes with components that have already experienced significant wear.

Two Becker references, one replacement vane specification. Customers searching for 90139600007 replacement carbon vanes may encounter the later reference 90141200007. VacAir retains both part numbers for identification purposes, helping maintenance teams and purchasing departments match older records, existing vane markings and current replacement requirements. If there is any uncertainty, our specialists can help confirm the correct part from the pump model and available identification details.

Before fitting replacement vanes, inspect the internal condition of the pump. Excessive carbon dust, restricted rotor slots, cylinder scoring, bearing wear or inadequate cooling can contribute to premature vane failure. Where the existing set has fractured or worn unevenly, the underlying cause should be established before new components are installed.

WN 124-243 maintenance inspection checklist:

CORRECT CARBON VANE ORIENTATION Before installing Becker WN 124-243 replacement carbon vanes, thoroughly clean the rotor slots and remove any accumulated carbon dust or fragments from the previous set. Inspect the slots for scoring, damage or contamination that could restrict vane movement. Each replacement vane should slide freely into its rotor slot without binding. 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. Check the actual vane profile and confirm the correct orientation for the particular pump and its direction of rotation before installation. Both the DX 4.16 and VX 4.16 require seven replacement vanes. Fit a complete matched set and inspect the cylinder running surface, rotor shaft and bearings before reassembly. If the previous vanes have suffered unusual wear or breakage, investigate the cause before returning the pump to operation. Always follow the relevant Becker manufacturer’s fitting and maintenance instructions. VacAir’s experienced engineers can provide advice on vane identification, professional fitting, pump inspection, servicing and mechanical repairs where required.
