ELMO RIETSCHLE KTA 40 REPLACEMENT CARBON VANES
The Elmo Rietschle KTA 40 uses carbon vanes as part of its dry-running rotary vane pumping mechanism. These vanes are wearing components and require inspection and eventual replacement as part of the pump’s maintenance programme.
VacAir supplies replacement carbon vanes for the KTA 40 under reference VA523879, corresponding to Rietschle OEM number 523879. Each vane measures 135 × 37 × 4 mm, and the pump requires six vanes for a complete replacement.
The KTA range includes several pump sizes, with different carbon vane dimensions and part numbers. Identifying the correct vane by its OEM reference is therefore important, particularly when maintaining multiple Rietschle pumps. This page covers the KTA 40 specifically, while the associated master page provides the consolidated information for part number 523879.
Alongside carbon vanes, VacAir supplies Elmo Rietschle spare parts and offers vacuum pump servicing and repairs for customers who need engineering support.

REPLACING KTA 40 CARBON VANES
|
The carbon vanes fitted to the Elmo Rietschle KTA 40 gradually reduce in height through normal operation. New replacement vanes measure 135 × 37 × 4 mm, with a minimum permitted vane height of 27 mm. Regular inspection and measurement help identify when replacement is necessary. If any vane has reached the 27 mm minimum height, the vanes should be replaced. The KTA 40 requires six carbon vanes for a complete change. Before fitting new vanes, inspect the rotor slots, cylinder surfaces and other internal components for signs of abnormal wear or damage. Recommended inspection points include: ✓ Rotor slots for cleanliness and unrestricted movement
✓ Cylinder walls for scoring or unusual wear
✓ Bearings and rotor condition
✓ Inlet filtration and possible airflow restrictions
✓ Carbon fragments or excessive deposits
✓ Signs of overheating or uneven vane wear
Important maintenance advice: If a vane has fractured, establish why it failed before installing replacements. Broken fragments or damaged internal surfaces may require additional attention.

For KTA 40 maintenance, our team can help identify suitable spare parts using the pump model, serial number and component references. This can be particularly useful when preparing for a scheduled shutdown or arranging a more extensive repair. ✓ KTA 40 carbon vanes and replacement sets

KTA 40 VANE FITTING & PUMP SERVICING
Customers with their own maintenance facilities can obtain the six 523879 replacement carbon vanes required for a KTA 40 vane change directly from VacAir.
Where a pump has developed unusual noise, reduced performance or repeated vane failures, a more thorough inspection may be appropriate. Problems involving the rotor, bearings or cylinder surfaces should be addressed rather than simply fitting another set of carbon vanes.
VacAir’s experienced OEM factory-trained engineers provide professional vacuum pump servicing, vane fitting, fault investigation and repairs. We can assist with both preventative maintenance and unexpected breakdowns.
Whether your KTA 40 needs routine attention or a more substantial repair, contact our engineering team to discuss the options available.
