VacAir supplies Rietschle 524003 replacement carbon vanes for the Rietschle DFT 140 and VFT 140 dry-running rotary vane pumps. Also identified by the alternative OEM reference 523556, these carbon vanes measure 180 × 55 × 6 mm, with four vanes required for a complete replacement in either pump model.
The DFT 140 and VFT 140 are industrial dry-running rotary vane machines used for pressure and vacuum generation respectively. Although the two models serve different applications, both use the same carbon vane specification. This allows replacement parts to be identified using either the pump model or the Rietschle OEM reference.
The 524003 carbon vane is a relatively large component compared with those used in smaller dry-running pumps. Its 180 mm length makes correct dimensional identification, suitable material selection and careful inspection of the pump’s internal condition important during maintenance.
Carbon vanes operate within the rotor slots, moving against the internal running surface as the rotor turns. Gradual wear is expected during normal service, but excessively worn or fractured vanes can reduce performance and potentially damage other internal components.
Primary OEM reference: 524003
Alternative OEM reference: 523556
VacAir reference: VA524003
Vane dimensions: 180 × 55 × 6 mm
DFT 140: 4 vanes per pump
VFT 140: 4 vanes per pump
The OEM references 524003 and 523556 identify the same replacement-vane specification for the models listed above. VacAir uses VA524003 as its primary product reference. If you are unsure which replacement is required, our technical team can assist with identification.

The carbon vanes fitted to Rietschle DFT 140 and VFT 140 pumps are wearing components. During operation, the vanes move within the rotor slots, helping to form the working chambers that generate the required pressure or vacuum. As the vanes wear, their dimensions gradually reduce. Continued operation beyond the manufacturer’s recommended wear limits may affect pump performance and increase the risk of damage to internal components. The four 180 × 55 × 6 mm carbon vanes should be checked for uneven wear, cracks, chipping and signs of abnormal contact with the internal running surfaces. When replacement is required, we recommend changing the complete set. Before installing replacement vanes, inspect: ✓ Rotor slots and free vane movement
✓ Internal running surfaces for scoring
✓ Rotor and shaft condition
✓ Bearings and excessive movement
✓ Inlet filtration and contamination
✓ Signs of overheating or uneven wear
Confirm the replacement vane dimensions and follow the manufacturer’s maintenance instructions when removing and installing new vanes. Care should be taken when handling the 180 mm components to avoid damaging their edges or corners. If the original vanes have fractured, investigate the cause before installing replacements. Scoring, contamination, bearing wear or damage to the rotor may require additional repair work.

VacAir has supplied replacement vacuum pump vanes and spares since 1996, supporting industrial users, engineers, distributors and specialist repair companies throughout the UK and overseas.
The Rietschle 524003 replacement carbon vane, also identified as 523556, is used in both the DFT 140 and VFT 140. Our master product page brings these two applications and both OEM references together, helping customers identify the correct replacement whether searching by part number or pump model.
Correct vane identification is particularly important for industrial dry-running rotary vane pumps. Both models require four carbon vanes measuring 180 × 55 × 6 mm. Checking the part reference, dimensions and quantity required helps avoid ordering errors and unnecessary maintenance delays.
Our technical team can assist with replacement-vane identification and related pump enquiries. VacAir also offers vacuum pump servicing, workshop repairs and fault investigation where damaged vanes or reduced pump performance may indicate additional mechanical problems.
Our Price Promise reflects our commitment to competitive replacement-vane pricing, supported by specialist product knowledge and practical engineering assistance.
What size are Rietschle 524003 carbon vanes?
Rietschle 524003 replacement carbon vanes measure 180 × 55 × 6 mm.
Are Rietschle 524003 and 523556 the same replacement vane?
Yes. Both OEM references identify the same 180 × 55 × 6 mm carbon vane specification for the Rietschle DFT 140 and VFT 140 pumps.
Which Rietschle pumps use 524003 carbon vanes?
Rietschle 524003 carbon vanes are listed for the DFT 140 and VFT 140 dry-running rotary vane pumps.
How many carbon vanes does a Rietschle DFT 140 require?
The Rietschle DFT 140 requires four carbon vanes per pump.
How many carbon vanes does a Rietschle VFT 140 require?
The Rietschle VFT 140 requires four carbon vanes per pump.
Should all four Rietschle 524003 vanes be replaced together?
VacAir recommends replacing all four vanes together during a complete vane change. The rotor slots and internal running surfaces should also be inspected for wear, contamination or damage.
What should I inspect before fitting replacement vanes?
Inspect the rotor slots, internal running surfaces, bearings and inlet filtration. Check for contamination, scoring, overheating or abnormal wear, particularly if the original vanes have fractured.
Can VacAir supply Rietschle 524003 vanes internationally?
