ELMO RIETSCHLE TR 81DVV REPLACEMENT CARBON VANES
For servicing the Elmo Rietschle TR 81DVV dry-running rotary vane pump, VacAir Superstore supplies correctly identified replacement carbon vanes. Whether you are planning a preventative maintenance shutdown or responding to a pump fault, our team can help you establish the appropriate vane specification and replacement quantity.
A complete TR 81DVV vane change requires seven carbon vanes. Each replacement measures 95 × 59 × 6 mm and is identified by Rietschle reference 514870 (extended reference 5148700000). VacAir identifies this vane as VA514870.
In the TR 81DVV, the carbon vanes move within the rotor slots as the pump operates. Friction during normal running gradually reduces their height. The vane starts at 59 mm high; the specified minimum permitted height is 45 mm. Measuring the vanes during servicing is important, but cracking, uneven wear or restricted movement also warrants investigation.
Although the TR 81DVV uses the same 95 × 59 × 6 mm vane dimensions as certain related pumps, the quantity in a complete set varies. The TR 81DVV, TR 81 and TR 80DVV take seven vanes; the TR 80D, TR 80DV and TR 80V take six. Check the full model designation before ordering.
VacAir also supplies Elmo Rietschle spare parts and provides vacuum pump servicing and repairs when a TR 81DVV service calls for more than a straightforward vane replacement.

RIETSCHLE TR 81DVV VANE INSPECTION & REPLACEMENT
|
During scheduled TR 81DVV maintenance, remove and inspect all seven carbon vanes in accordance with the pump manufacturer’s instructions. Record their measured heights and look for damage that could indicate problems with the rotor, filtration or internal running surfaces. Each new vane measures 95 × 59 × 6 mm, giving an initial height of 59 mm. Do not allow the vanes to wear below the 45 mm minimum height. A vane with chips, cracks or abnormal wear may require attention even if its measured height remains above the limit. TR 81DVV maintenance inspection checklist: ✓ Measure the height of all seven carbon vanes ✓ Inspect vane edges for chips or fractures ✓ Check the vanes slide freely in the rotor slots ✓ Examine the cylinder wall for scoring or damage ✓ Inspect the rotor and shaft condition ✓ Check bearings for excessive wear or movement ✓ Inspect inlet filtration and accumulated carbon dust ✓ Check for contamination or evidence of overheating ✓ Investigate any abnormal or uneven vane wear
TR 81DVV minimum vane height: The original height is 59 mm and the minimum permitted height is 45 mm. When renewal is required, replace all seven vanes together and check for the cause of any unusual wear before restarting the pump.

ELMO RIETSCHLE TR 81DVV SPARE PARTS
|
Alongside TR 81DVV replacement carbon vanes, VacAir can assist with identifying filters and other spare parts needed for planned servicing or repair work. Providing the complete pump designation and, where available, its serial number helps our team check the required components. A TR 81DVV service is an opportunity to examine the condition of the inlet filter, rotor slots, bearings and cylinder surface. Excessive carbon dust, dirt or mechanical damage can affect vane movement and may shorten the life of a newly installed set. Since 1996, VacAir has supported industrial customers with vacuum pump vanes and spare parts. For this model, quote TR 81DVV and Rietschle reference 514870 or 5148700000 (VacAir VA514870) to help identify the correct vane. ✓ Rietschle 514870 replacement carbon vanes ✓ Inlet filters and maintenance components ✓ Vacuum pump spare parts and repair support ✓ Technical assistance identifying correct parts |

TR 81DVV VANE FITTING & PUMP SERVICING
The TR 81DVV uses seven Rietschle 514870 carbon vanes. VacAir can supply the replacement set to your maintenance team, or you can enquire about professional vane fitting and wider pump servicing.
Before installing replacements, measure the existing vanes against the 45 mm wear limit and examine the internal running surfaces. Check that the rotor slots are clean and the vanes can move freely, and assess the condition of the bearings and inlet filtration.
Broken vanes, overheating, increased noise or loss of performance should prompt further checks before the TR 81DVV is returned to service. Fitting seven new vanes will not correct a scored cylinder, defective bearing or another underlying mechanical fault.
Where in-house fitting is not practical, VacAir’s OEM factory-trained engineers can assist with pump inspection, fault finding, carbon vane replacement and servicing.
