VacAir supplies Rietschle 523399 replacement carbon vanes for the Rietschle DFT 250 and VFT 250 dry-running rotary vane pumps. Measuring 320 × 55 × 6 mm, these large-format carbon vanes are used in industrial vacuum and pressure applications, with four vanes required per pump.
The DFT 250 and VFT 250 use the same replacement vane reference, making identification straightforward when the pump model and part dimensions are known. Both machines use carbon vanes as wearing components, requiring inspection and replacement in accordance with the manufacturer’s maintenance recommendations.
The 523399 vane is considerably longer than those used in many smaller Rietschle pumps. Correct dimensions, suitable carbon material and careful inspection of the pump’s internal condition are important when preparing for a vane change, particularly where the original vanes have fractured or worn unevenly.
Rietschle OEM reference: 523399
Vane dimensions: 320 × 55 × 6 mm
DFT 250: 4 vanes per pump
VFT 250: 4 vanes per pump
Our VacAir replacement reference is VA523399. If you are identifying parts from an existing vane, pump nameplate or maintenance record, our technical team can assist with confirming the correct replacement.

The carbon vanes in Rietschle DFT 250 and VFT 250 pumps are wearing components. As the rotor turns, the vanes move within their slots and form the working chambers used to move air through the pump. Over time, normal operation causes wear. Routine inspection and timely replacement help maintain performance and reduce the risk of internal damage associated with excessively worn or fractured vanes. When inspecting the pump, check: ✓ Rotor slots and free vane movement
✓ Rotor and shaft condition
✓ Internal running surfaces for scoring
✓ Bearings and excessive movement
✓ Inlet filtration and contamination
✓ Signs of overheating or uneven wear
With a vane length of 320 mm, careful handling and inspection are particularly important. Check all four rotor slots, confirm the replacement dimensions and follow the manufacturer’s instructions for safe dismantling and reassembly. If the existing vanes have fractured or worn unevenly, investigate the cause before installing replacements. Damage to the rotor or internal running surfaces may require repair rather than a vane change alone.

Inspect the rotor slots and internal running surfaces before fitting replacement carbon vanes.

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 523399 replacement vane is a large-format carbon component measuring 320 × 55 × 6 mm. Our master product page brings together the DFT 250 and VFT 250 applications, making it easier to identify the correct replacement when searching by pump model or original part number.
Accurate vane identification is important for industrial rotary vane pumps. Matching the OEM reference, dimensions and number of vanes helps avoid delays during planned maintenance or unexpected repairs. Both listed models require four vanes per pump.
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 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.
