BECKER KDT 3.140 REPLACEMENT VANES

The Becker KDT 3.140 uses a set of 4 carbon graphite vanes. VacAir supplies replacement vanes manufactured to the correct 240 × 48 × 4 mm dimensions for this model.

The vane fitted to the KDT 3.140 is identified by Becker vane code WN 124-031. The Becker OEM reference for the complete four-vane set is 90133400004, with VacAir replacement reference VA901334.

Replacement vanes are held in UK stock, together with service kits, filters and other Becker pump parts. Technical support is also available if you are unsure whether vane wear is responsible for a loss of pump performance.

Need to identify the vane rather than the pump?
See our Becker WN 124-031 replacement vane page for vane dimensions, compatible Becker models and the different 901334-series OEM set references.

REPLACING BECKER KDT 3.140 CARBON VANES

The KDT 3.140 uses four carbon vanes. When carrying out routine maintenance, all four should be inspected for wear, damage or abnormal wear patterns. New WN 124-031 vanes have a height of 48 mm and should be replaced before reaching the 31 mm minimum wear height.
With the pump opened for a vane change, it is also sensible to inspect:
✓ Rotor and rotor slot condition
✓ Cylinder body and internal surfaces
✓ Bearings
✓ Inlet and exhaust filters
✓ Relief valve operation
✓ Carbon dust, contamination or signs of overheating
Broken or chipped vanes can leave carbon fragments inside the pump. Remove all debris and clean the rotor slots thoroughly before installing the replacement vanes.

KDT 3.140 VANE FITTING & PUMP SERVICING

Worn vanes can result in reduced pump performance, but loss of pressure, excessive noise or increased carbon dust can also indicate other mechanical or service issues.
