Carbon vanes are wearing components in dry-running rotary vane pumps and compressors. Over time, normal contact with the pump’s internal running surfaces reduces vane length and may affect performance. When servicing a Rietschle DTA 140, KTA 140 or VTA 140 using the 523885 vane specification, inspect the existing vanes for wear, chipping, fractures and uneven contact marks. Before fitting replacement vanes, check: ✓ Rotor slots and free vane movement ✓ Internal running surfaces for scoring ✓ Bearings and rotor condition ✓ Inlet filtration and contamination ✓ Signs of overheating or uneven wear Replace all vanes in the pump together, using the correct quantity for the model. Follow the manufacturer’s service instructions and verify vane dimensions and orientation before reassembly. Engineering advice:
If a vane has fractured, chipped or become jammed, identify the cause and inspect the pump for internal damage before restarting. Ensure all dust and fragments are cleared from all chambers. |
Inspect the pump before installing a new set of carbon vanes. |
