    Every tenth.
    Every millimetre.
    Every rotation.

    A vane is not defined by length alone. Thickness, width, edge chamfer, surface finish and material can all affect fit and operational behaviour.

    Engineered geometry

    We assess nominal dimensions, orientation, edges and relevant characteristics of your sample or drawing.

    Material in context

    Vacuum level, temperature, working environment and lubrication are considered before recommending an option.

    04 / A SIMPLE PROCESS

    You share the details
    We assess the solution

    You do not need to know the spare-part number: the pump information is enough to begin the assessment.

    01 / 03

    Tell us about your equipment

    Send the make, model, previous reference and vane dimensions, if available. Photos, drawings and samples are welcome.

    03 / 03

    Receive a tailored offer

    We confirm feasibility, suggested material, quantity, price and estimated lead time, subject to technical verification.

    MEASUREMENTS WE NEED

    Provide length, width and thickness in millimetres. You must specify whether the pump runs dry (oil-free) or is oil-lubricated so we can verify compatibility. The rotor vane count also helps.

    Technical checks before manufacturing

    Assessment starts with the actual machine reference, not an approximate geometry. Every critical feature must be checked against the duty conditions and available technical documentation.

    01 / 04

    Dimensions and wear

    We review length, width and thickness at several points. A worn vane may no longer retain its nominal dimensions, so samples, drawings and the equipment manual are compared before tolerances are agreed.

    02 / 04

    Chamfers and grooves

    We check face, position, direction and number of grooves. The reference G11++ vane has three grooves, whereas the Kevlar example has none. Neither layout is assumed correct for another pump.

    03 / 04

    Material and lubrication

    You must identify whether the pump runs dry or is oil-lubricated. HARDVANES® EKVAC EVO+ carbon graphite, epoxy G11++ fibre and other engineered materials are assessed for the intended application.

    04 / 04

    Machining and surface finish

    We assess precise milling, flatness, parallelism and edge finishing. Fine polishing or a mirror-like finish is considered only when the chosen compound and functional specification allow it.

    Minimum manufacturing order: 4 units. Share a drawing or CAD file and request a technical assessment.

    Frequently asked questions

    Fifteen detailed technical answers about custom vacuum-pump and compressor vanes, materials, dimensions and manufacturing.

    15 TECHNICAL ANSWERS

    Which vane material should I choose?

    Carbon graphite is used in many dry-running rotary vane vacuum pumps and compressors. Epoxy G11++ fibre and Kevlar composites are intended for different designs and working conditions. We do not select materials by appearance alone: pump make, model, lubrication, temperature and duty must be assessed before confirming suitability.

    HARDVANES · TECHNICAL REFERENCE

    Can you manufacture custom dimensions?

    Yes. We assess vanes that are not listed in catalogues, difficult-to-source spares and discontinued equipment. We can work from nominal dimensions, an existing sample or a technical drawing. In addition to length, width and thickness, we review the material, bevels, grooves and quantity before confirming feasibility.

    HARDVANES · TECHNICAL REFERENCE

    How do I know if I need a bevel?

    A bevel is a machined feature on one or more vane edges. Its position, direction and geometry may affect installation and movement inside the rotor slot. Not all vanes have a bevel, and there is no universal orientation. If you are unsure, include photographs of both broad faces and the edges.

    HARDVANES · TECHNICAL REFERENCE

    What are grooves and when are they needed?

    These are machined features found on certain technical-fibre vanes. Their number, position and shape depend on the equipment design; they should not be added by default. Our reference G11++ vane has three transverse grooves on its broad face, while the pictured Kevlar Pharaontex 999 vane has none.

    HARDVANES · TECHNICAL REFERENCE

    What is the minimum manufacturing order?

    The minimum order for custom-made vanes is 4 units. You may request 4 or more vanes; we review dimensions, material and application before confirming feasibility, price and lead time. If the equipment manufacturer recommends replacing the complete rotor set, follow that guidance.

    HARDVANES · TECHNICAL REFERENCE

    How should I measure a vane?

    We need three dimensions in millimetres: length (L), width or height (W), and thickness (T). Use a suitable caliper and measure at several points. A worn vane may have lost nominal radial height, so compare the readings with an original reference, drawing or equipment manual whenever possible.

    HARDVANES · TECHNICAL REFERENCE

    Can you supply vanes for different brands?

    We can assess vanes for a range of vacuum-pump and compressor manufacturers, including older models with limited spare-part availability. Brand alone does not establish compatibility. The exact pump reference, geometry, material and operating conditions must be checked before treating a new vane as suitable.

    HARDVANES · TECHNICAL REFERENCE

    Are custom vanes equivalent to original spares?

    A custom vane must reproduce the relevant requirements of the part specified for the equipment, including dimensions, material, finish, bevels and grooves where applicable. Two parts with identical overall dimensions do not necessarily perform identically. We review suitability before quoting rather than claiming universal equivalence.

    HARDVANES · TECHNICAL REFERENCE

    How long do manufacture and delivery take?

    Lead times depend on material availability, machining complexity, necessary checks and the quantity requested. The destination country and shipping method also affect delivery. We provide an estimated manufacturing and dispatch schedule with the quotation after reviewing the request; there is no single lead time for every custom vane.

    HARDVANES · TECHNICAL REFERENCE

    How long does a vane last?

    There is no universal service life expressed in hours. Wear depends on the pump, load, actual operating temperature, rotor-slot condition, cleanliness and vane material. Reduced performance, unusual noise or a measurement outside the manufacturer’s wear limit are reasons to inspect the unit.

    HARDVANES · TECHNICAL REFERENCE

    How are replacement vanes installed?

    Before maintenance, stop the equipment, isolate its power supply and allow it to cool under the applicable safety procedure. Check the rotor, slots and possible wear debris. Bevel orientation and installation sequence vary by model: follow the equipment manufacturer’s instructions and never force the vanes into place. You can also consult our Spanish-language vane replacement and maintenance guide; the equipment manual remains authoritative.

    HARDVANES · TECHNICAL REFERENCE

    Are the materials suitable for high temperatures or harsh media?

    Graphites and composite materials have different thermal, mechanical and chemical properties. A raw material’s temperature rating does not automatically equal the permitted operating temperature of a pump. To assess a suitable vane, we need to know the process, handled medium, lubrication and actual working conditions.

    HARDVANES · TECHNICAL REFERENCE

    What details do you need for a quotation?

    Provide the pump or compressor make and model, previous vane reference if available, length, width, thickness, material and quantity. You must indicate whether the pump runs dry or is oil-lubricated; contact us first if you do not know. Provide photos of both broad faces, bevels and grooves, or a dimensioned PDF drawing. The configurator also accepts CAD, DWG, DXF, STEP, STP, IGES and IGS files (one file, up to 3 MB). These details help us assess feasibility, pricing and expected manufacturing lead time.

    HARDVANES · TECHNICAL REFERENCE

    Can you reproduce a special design?

    Yes. We review special bevels, grooves, machined profiles and other non-standard geometries. A physical sample or dimensioned drawing helps identify critical details. Manufacturing feasibility depends on the shape, material and required tolerances and must be confirmed through technical review.

    HARDVANES · TECHNICAL REFERENCE

    Do you provide technical guidance?

    Yes. We help identify references, check dimensions, explain material differences and prepare custom-vane requests. If a pump has mechanical faults, diagnosis and repairs must be handled by qualified personnel. The aim is to specify a documented replacement appropriate to your application.
