Rietschle Vacuum Pump Vanes
CARBOLVE manufactures model-matched carbon and composite vanes for selected Rietschle dry-running vacuum pumps, compressors, pressure-vacuum units and selected oil-lubricated pumps. Each request is reviewed against the complete pump model, vane dimensions, material construction and operating conditions before quotation.

Compatible Vanes for Selected Rietschle Pump Series
Rotary vane performance depends on the relationship between the vane, rotor slot, cylinder surface, operating medium and pump conditions. A replacement selected only by brand name can still have the wrong dimensions, edge geometry or material.
CARBOLVE evaluates replacement and custom vane projects from the full pump model, original part number when available, drawing, physical sample and operating data. This supports current equipment, discontinued models, maintenance replacements and repeat-order programs without assuming that one material or vane design fits every Rietschle pump.

Rietschle Replacement Vane Range
Select the operating role first, then confirm the complete pump model and vane construction. Series names below are compatibility references rather than a claim that every model uses the same vane.
Dry-Running Vacuum Pump Carbon Vanes
Model-matched carbon graphite vanes for selected dry-running rotary vane vacuum pumps. Application-matched carbon graphite can provide low friction, self-lubricating behavior, controlled wear and dimensional stability without an oil-lubricated compression chamber.
Selection cue Confirm the complete pump model, vane quantity, thickness, width, length, edge geometry and vacuum duty.
Dry-Running Compressor Carbon Vanes
Carbon vanes evaluated for selected dry-running rotary vane compressors. Positive-pressure operation changes the thermal and mechanical conditions, so a vacuum-pump vane should not be assumed to be interchangeable.
Selection cue Confirm working pressure, speed, temperature, duty cycle, gas or medium and complete vane geometry.
Pressure-Vacuum Combination Pump Carbon Vanes
Carbon vanes for selected units that generate vacuum and pressure in the same equipment. Material direction and geometry must be evaluated against both operating sides rather than matched from the series name alone.
Selection cue Confirm the complete model, vacuum and pressure conditions, vane orientation, dimensions and operating cycle.
Composite Vanes for Selected Oil-Lubricated Pumps
Carbon-fiber composite, resin-impregnated carbon or glass-fiber composite vanes can be evaluated for selected oil-lubricated Rietschle pump applications when the original construction and operating conditions require these materials.
Selection cue Confirm the original vane material, lubrication method, oil compatibility, temperature, dimensions and pump model. Aluminum vanes are outside the confirmed supply scope.
Why Model Name Alone Is Not Enough
Similar model names, different vane details
A series name may cover more than one pump size or revision. Ordering from an incomplete model reference can lead to incorrect length, thickness, quantity or edge geometry.
CARBOLVE reviews the complete nameplate model, original part number when available, dimensions, drawing or sample before confirming the manufacturing direction.
A worn sample may not show the original size
An operating vane can become shorter, thinner or unevenly worn. Copying one worn dimension without checking the pump model and other geometry can reproduce the wear rather than the intended fit.
Where possible, combine the sample with the complete model, original part number, multiple measurements and photographs of chamfers, slots and contact faces.
The wrong material can change pump behavior
Dry-running carbon graphite, resin-impregnated carbon, carbon-fiber composite and glass-fiber composite are not automatic substitutes for one another. Lubrication, temperature, humidity, gas exposure and mating surfaces influence material selection.
CARBOLVE reviews the material direction together with the operating conditions instead of selecting from appearance alone.
Small geometry differences affect installation
Chamfer position, slot geometry, edge condition and dimensional clearance affect how a vane moves inside the rotor slot.
Custom machining can cover thickness, width, length, chamfers, slots and grade direction based on a verified drawing, sample and operating information.
Choose by Pump Function Before Choosing Material
| Pump function | Series examples | Typical vane direction | Main conditions to confirm |
|---|---|---|---|
| Dry-running vacuum | VTE, VTN, VTR, VLT, VTA | Application-matched carbon graphite | Vacuum level, speed, temperature, humidity, duty cycle and complete vane dimensions |
| Dry-running pressure | DTE, DTN, DTR, DLT, DTA | Application-matched carbon graphite | Working pressure, discharge temperature, gas or medium, speed and continuous or intermittent duty |
| Combined pressure and vacuum | KTN, KTR, KLT, KTA | Carbon graphite selected for the complete operating cycle | Vacuum and pressure conditions, model revision, vane orientation, dimensions and quantity |
| Selected oil-lubricated pumps | V-VC, VCA/VCE, VCB, VCS, VGD | Carbon-fiber composite, resin-impregnated carbon or glass-fiber composite where specified | Original construction, lubricant, temperature, pump model, sample or drawing and dimensional details |
Series references help identify the project but do not establish interchangeability. The exact model, vane construction and dimensions must be reviewed before production.
How to Compare Vane Materials
The correct material is the one that matches the pump design and operating environment. Material appearance alone is not a reliable identification method.
Carbon Graphite
Best-fit direction: Selected oil-free and dry-running vacuum, pressure and combination pumps.
What it offers:
Application-matched carbon graphite can provide low friction, self-lubricating behavior, controlled wear and dimensional stability in dry-running systems.
What to verify:
Pump speed, temperature, humidity, gas or medium, contact surfaces, duty cycle and required grade direction.
Resin-Impregnated Carbon
Best-fit direction: Selected applications that specify an impregnated carbon construction.
What it offers:
Resin impregnation is commonly used to reduce open porosity and modify mechanical properties. The resin system also creates temperature and chemical-compatibility limits that must be reviewed.
What to verify:
Original material specification, impregnation system, temperature, lubricant or medium and dimensional requirements.
Carbon-Fiber Composite
Best-fit direction: Selected pump designs that specify a reinforced composite vane.
What it offers:
A reinforced composite construction can provide a different balance of mass, strength and dimensional behavior from conventional carbon graphite.
What to verify:
Original construction, fiber and resin direction, lubrication, rotor and cylinder compatibility, temperature and edge geometry.
Glass-Fiber Composite
Best-fit direction: Selected oil-lubricated pump designs that specify a glass-fiber-reinforced vane.
What it offers:
Glass-fiber composite vanes are application-specific components and should be matched to the original resin system, reinforcement and wear conditions.
What to verify:
Pump model, original vane construction, lubricant, temperature, dimensions, contact surfaces and duty cycle.
Closing note: Do not replace an original carbon, composite or metal vane with another material solely because the dimensions appear similar. Material substitution requires an application review.
Information Needed to Identify a Replacement Vane
A complete identification package helps separate visually similar vanes and reduces avoidable specification mismatches.
- 1 Record the full pump brand, model and nameplate information.
- 2 Include the original part number or vane-set reference when available.
- 3 Measure thickness, width and length at multiple points.
- 4 Photograph and measure chamfers, bevels, slots, radii and unusual edge details.
- 5 Show the orientation of asymmetrical features relative to rotation when applicable.
- 6 Confirm the number of vanes required for one pump or one set.
- 7 Describe vacuum or pressure conditions, speed, temperature, humidity, gas or medium and duty cycle.
- 8 State the required quantity, destination country and any identification or packing requirements.
Caution note: A used vane may be below its original dimensions. A drawing or original specification should take priority when available; otherwise the worn sample must be reviewed together with the pump model and operating information.
From Vane Identification to Finished Components
Multiple Material Routes
CARBOLVE can manufacture carbon graphite, resin-impregnated carbon, carbon-fiber composite and glass-fiber composite vane products. The material route is selected from the original component and operating requirements, not from a generic brand cross-reference.
Drawing- and Sample-Based Custom Machining
Available customization includes thickness, width, length, chamfers, slots, contact features and grade direction. Projects can be evaluated from technical drawings, physical samples, photographs and equipment information.
Model-Matched Replacement Support
Replacement vane requests are reviewed for selected pump models rather than presented as universal interchange parts. This supports current equipment, maintenance requirements and obsolete-component replacement projects.
Inspection Before Shipment
CARBOLVE’s production workflow includes incoming material review, in-process checks, surface inspection and final verification of agreed dimensions, appearance, quantity, identification and packing.
Supply Options for Different Replacement Programs
Equipment Maintenance
Replacement vanes can be reviewed for planned maintenance, worn-vane replacement and equipment restoration. Confirm the service limit from the applicable pump manual before using symptoms alone to decide replacement timing.
Distributor and Repeat Orders
For repeat purchasing, maintain one approved specification for each pump model, vane material, dimensions, quantity per set and identification requirement. Do not combine visually similar vanes under one item without confirming interchangeability.
Custom and Obsolete Components
When an original part is unavailable, CARBOLVE can evaluate a drawing or physical sample together with pump information and operating conditions. A worn sample is treated as a reference, not automatically as the original dimensional standard.
Manufacturing and Inspection for Custom Vane Projects
CARBOLVE manufactures carbon and graphite components for equipment manufacturers, distributors and maintenance companies. Production is evaluated from drawings, physical samples, equipment models, dimensions, material requirements and operating conditions.
Relevant processes include grinding, drilling, slotting, surface finishing and drawing-based machining of custom geometries. Incoming material review, in-process checks, surface inspection and final verification are followed by protective packing and international delivery coordination.
- Technical review before material and dimension confirmation
- Sample or prototype stage when required by the project
- Inspection of agreed dimensions, surface and edge condition
- Identification, protective packing and export communication

- Original Construction
- Operating Conditions
Are CARBOLVE vanes genuine Rietschle parts?
How can I confirm whether a vane is compatible with my pump?
Start with the full nameplate model rather than a shortened series name. Add the original part number when available, the number of vanes per set, complete dimensions and clear photographs of every edge feature. Also identify whether the pump operates as a vacuum pump, compressor or combined pressure-vacuum unit.
Compatibility should cover geometry, material and operating conditions. A vane with matching length and width may still be unsuitable if its thickness, chamfer, slot, material construction or operating environment differs.
What are common signs of worn carbon vanes?
Possible signs include reduced vacuum or pressure, longer pump-down time, unusual noise, higher operating temperature, increased carbon dust or unstable output. These symptoms can also come from filters, seals, bearings, leakage or other pump conditions, so they are not a complete diagnosis.
Inspect and replace vanes according to the applicable pump manual and model-specific wear limits. Isolate the equipment from power and pressure before inspection, and use a qualified technician where required.
How should carbon vanes be inspected?
Check each vane for remaining height, uneven wear, chipping, cracks, scoring, burned areas and damaged chamfers or slots. Confirm that the vane can move correctly in a clean rotor slot and examine the cylinder and rotor for conditions that could damage a new set.
Do not publish one universal minimum vane dimension. Wear limits and replacement procedures are model-specific and should come from the correct pump documentation.
How can vane service life be supported?
Keep inlet filtration, cooling and ventilation in the condition specified by the pump manufacturer. Prevent unsuitable dust, liquid or process media from entering the pump, and follow the recommended inspection interval for the actual duty cycle.
Correct material, slot cleanliness, vane orientation and pump operating conditions all matter. A longer-life claim is not meaningful unless the vane and pump are compared under the same model, load, environment and maintenance conditions.
What affects the price of a replacement vane set?
Quotation depends on the material construction, complete dimensions, geometry, quantity per set, order quantity, inspection requirements, identification and packing. A model name alone may not provide enough information for an accurate quotation.
Compare more than unit price. Confirm whether the quotation covers the correct material, a complete set or individual vanes, dimensional verification and the required packing and identification.
What should be checked before installing composite vanes?
Confirm that the composite construction matches the original pump requirement. Check the complete model, lubrication method, vane orientation, rotor-slot condition, contact surfaces and the applicable installation manual.
Installation should be completed with the equipment isolated from power, vacuum and pressure. Clean the rotor slots using the method permitted by the pump manufacturer, never force a vane into a slot, and follow the manual’s requirement for replacing individual vanes or a complete set.
What should I verify when selecting a replacement-vane supplier?
Ask the supplier to identify the proposed material route, dimensional basis, geometry review, inspection criteria and whether the product is an original or independently manufactured replacement. Provide enough pump and operating information for the supplier to evaluate suitability instead of relying on a brand-name lookup alone.
CARBOLVE supports review from equipment information, drawings, samples and operating conditions, followed by material and dimension confirmation before production.
