The Elmo Rietschle KLT 25 relies on carbon vanes as part of its dry-running rotary vane pumping mechanism. Over time, these components wear through normal operation and should be checked during scheduled maintenance. VacAir supplies replacement vanes to help keep KLT 25 pumps operating reliably.
Each KLT 25 requires 6 carbon vanes measuring 85 × 39 × 4 mm for a complete change. The corresponding Rietschle OEM reference is 513431, with VacAir replacement reference VA513431.
Identifying vanes by both pump model and original part number helps avoid ordering errors, especially where the same carbon vane specification is used across different Rietschle pump families. This page covers the six-vane requirement for the KLT 25, while our master product page provides the shared OEM reference information.
VacAir can also assist with Elmo Rietschle spare parts and vacuum pump servicing and repairs.

Carbon vanes are consumable components within the KLT 25 vacuum pump. As the rotor turns, the vanes operate against the internal cylinder surface and gradually wear. Their condition should be monitored according to the manufacturer’s maintenance recommendations. When a complete replacement is required, fit six correctly specified 513431 carbon vanes. The opportunity should also be taken to inspect the condition of the pumping chamber and other components that may influence vane life. Inspection points include: ✓ Rotor slots for cleanliness and free vane movement
✓ Cylinder surfaces for scoring or abnormal wear
✓ Bearings and rotor condition
✓ Inlet filtration and possible restrictions
✓ Carbon dust or fragments from damaged vanes
✓ Evidence of excessive temperature or uneven wear
Before fitting new vanes: If the pump has experienced a vane breakage, unusual noise or premature wear, investigate the cause and inspect the internal components. Follow the manufacturer’s fitting instructions and service limits.

Our business history dates back to 1996, and we work with customers who need reliable replacement components and knowledgeable technical support. For a planned KLT 25 overhaul, our team can assist with identifying additional parts using the pump model, serial number and existing component references. This can help maintenance teams prepare the components they require before taking a pump out of service. ✓ Replacement carbon vanes and vane sets

VacAir supports customers carrying out their own KLT 25 maintenance by supplying the six 513431 carbon vanes required for a complete change. The correct dimensions and part references make it easier to identify replacement components before dismantling the pump.
Where a pump has been running with excessively worn vanes, it may be necessary to inspect the rotor, cylinder and bearings before fitting replacements. This is especially important following a vane fracture or repeated premature wear.
Customers who prefer professional assistance can use VacAir’s OEM factory-trained engineers for carbon vane fitting, vacuum pump servicing and repairs.
Our service team can assist with both planned maintenance and the investigation of pumps that have developed performance problems or mechanical faults.
