Technical help and UK stock availability.
The Becker DTLF 250 requires five carbon graphite vanes for a complete vane replacement. VacAir supplies the correct WN 124-196 vane from UK stock for servicing and maintenance of this pump model.
Each vane measures 355 × 65 × 5 mm. When new, the vane height is 65 mm, with a confirmed minimum wear height of 41 mm. These measurements provide a useful reference when checking the condition of vanes removed from an existing DTLF 250.
The VacAir replacement reference is VA901367. The associated Becker OEM reference is 90136701005, while WN124-196 is the vane identification code that may be used when identifying the component itself.
Because WN 124-196 is shared by a number of Becker VTLF, DTLF and DVTLF pumps, this page is specifically focused on the DTLF 250 installation: five vanes per pump, the confirmed wear dimensions and the dedicated DTLF 250 service kit.

Vanes are wearing components, so their height reduces progressively during operation. The DTLF 250 uses five WN 124-196 vanes, and the condition of the set can be checked by measuring vane height during planned maintenance.
A new vane is 65 mm high. The confirmed minimum wear height is 41 mm, providing a straightforward reference when measuring vanes that have been removed from the pump.
If replacement is required, VacAir can supply the complete five-vane requirement or individual replacement vanes. For customers carrying out a wider DTLF 250 maintenance programme, a dedicated service kit containing the vane set and filtration components is also available.

When the DTLF 250 is receiving more than a straightforward vane change, VacAir can also supply the model-specific DTLF 250 service and maintenance kit. The kit brings together the complete five-vane requirement with the filtration components listed for this model. It contains 5 × WN 124-196 carbon vanes, together with a 909534 inlet filter and two 909510 exhaust filters. This gives customers carrying out planned DTLF 250 maintenance a convenient option where the vanes and filters are being renewed together rather than ordered as separate items. ✓ 5 × WN 124-196 replacement vanes

Supplying the correct parts is only one part of VacAir’s support for Becker pumps. If your own maintenance team is replacing the DTLF 250 vanes, we can supply the vane set, service kit and associated spare parts required for the work.
For customers who require engineering support, VacAir has highly experienced OEM factory-trained engineers who can replace the DTLF 250 vanes on site or carry out servicing in our specialist workshop.
Our workshop can also undertake a full pump overhaul where the DTLF 250 requires more extensive attention than routine vane and filter replacement.
