Becker WN124-247 Vanes 90141000007, 90139900007

IDENTIFYING BECKER VANE WN 124-247

BECKER PUMPS USING WN 124-247 VANES

WN 124-247 replacement vanes are used in the Becker DX 4.25 and VX 4.25 dry-running rotary vane pumps. The current Becker reference is 90141000007.

REPLACING BECKER WN 124-247 CARBON VANES

VacAir Superstore stocks and supplies Becker WN 124-247 replacement carbon vanes for the Becker DX 4.25 and VX 4.25 dry-running rotary vane pumps. The vanes measure 63 × 41 × 4 mm and are available under VacAir reference VA901410. The current Becker OEM part number is 90141000007, which supersedes the earlier reference 90139900007.

Both the DX 4.25 and VX 4.25 use seven carbon vanes per pump. Maintaining the correct vane dimensions, quantity and profile is essential when carrying out a service. Although other Becker pumps use carbon vanes with superficially similar dimensions, the WN 124-247 identification and corresponding OEM reference should be checked rather than selecting replacements solely by appearance.

A new WN 124-247 carbon vane has a height of 41 mm. During normal pump operation, the vane gradually wears as it moves within the rotor slot and maintains contact with the cylinder running surface. The specified minimum wear height is 28 mm. Measuring the height of the removed vanes provides a useful indication of their remaining service life, but physical condition and wear pattern are equally important.

Once a vane reaches the 28 mm wear limit, the complete seven-vane set should be replaced. We recommend replacing all seven together, rather than combining new carbon vanes with older, partially worn components. Cracking, chipped edges, abnormal dust accumulation or markedly uneven wear can also justify replacement and further inspection before the stated minimum height is reached.

For customers maintaining older Becker DX 4.25 or VX 4.25 pumps, the original parts information may specify 90139900007. This is the previous Becker reference for WN 124-247; the current number is 90141000007. VacAir retains both references to help maintenance departments, purchasing teams and service engineers identify the correct replacement vanes without confusion.

Replacing the vanes is also an opportunity to assess the general mechanical condition of the pump. Check that the rotor slots are clean and undamaged, inspect the cylinder running surface, and investigate any unusual bearing noise, restricted cooling airflow or contamination. New vanes should not simply be fitted over an unresolved fault that caused premature wear or failure of the previous set.

WN 124-247 inspection and maintenance checklist:

FITTING AND VANE ORIENTATION Before fitting new WN 124-247 replacement carbon vanes, remove the old set and thoroughly clean the rotor slots. Check for damaged edges, trapped carbon dust and signs that the previous vanes have been sticking or binding during operation. Each replacement vane must move freely in its slot without requiring force. The higher edge of the carbon vane is the leading edge. The chamfer follows behind, as illustrated in the fitting diagram. Confirm the correct vane orientation for the pump’s direction of rotation and follow the applicable Becker manufacturer’s instructions. The Becker DX 4.25 and VX 4.25 each require seven vanes. Install a complete matched set, taking care not to damage the carbon edges during handling. Inspect the rotor, cylinder and bearings before reassembly, particularly where the removed vanes have suffered abnormal wear. VacAir’s experienced engineers can assist with correct vane identification, fitting advice and professional pump servicing. Where damage extends beyond normal vane wear, our workshop can investigate the cause and carry out repairs before the pump is returned to operation.

More than 40 years of combined former Becker UK agent experience. Our senior team has extensive practical knowledge of Becker vacuum pumps, their operating characteristics and the spare parts required to maintain them. That experience is valuable when older OEM references are involved, a vane marking is difficult to read or a customer needs to understand why a replacement set has worn prematurely.

Competitive prices backed by our Price Promise. We work hard to provide quality replacement carbon vanes at attractive prices without compromising technical support. Our Price Promise and Customer Promises set out the conditions under which we will match a qualifying lower UK price for a genuinely comparable replacement vane. Customers can request a quotation with confidence that we understand both the product and its application.

ISO 9001:2015 certified and committed to customer satisfaction. VacAir operates an externally audited ISO 9001:2015 quality management system. We place considerable importance on accurate technical information, dependable service, consistent processes and honest customer relationships. Our reputation has been built through years of supplying the correct products and supporting the people who rely on them.

OEM-trained engineers and specialist repair facilities. VacAir can provide much more than a replacement vane set. Our experienced engineers can fit carbon vanes, inspect the internal condition of a pump and investigate faults that may have caused premature wear or mechanical failure. Our dedicated Becker vacuum pump repair and refurbishment workshop offers professional servicing, fault diagnosis and repairs at competitive rates.

Becker spares, filters and complete pump support. In addition to WN 124-247 carbon vanes, we stock and supply a comprehensive selection of Becker spare parts, including OEM components, replacement filters and routine service items. Customers can deal with a specialist supplier capable of helping with both straightforward maintenance and more involved pump problems.
