Key Evaluation Matrix

Metric	Typical Range	Why It Matters
Thickness Tolerance	+/- 0.01 mm	Ensures free sliding in the rotor slot without gas leakage.
Slot Fit	Length, width, thickness, and edge chamfer from sample	A tight vane can seize; a loose vane reduces vacuum and accelerates wear.
Impregnation	Resin or specialty treatment by pump duty	Impregnation changes wear rate, strength, and self-lubricating behavior.
Failure Mode	Chipping, edge wear, cracking, or short service life	The current failure pattern is the fastest route to material selection.

Engineering Datasheet

Product-Level Technical Specifications

Values below are RFQ planning targets, not blanket guarantees. Final acceptance criteria should be frozen against drawings, process conditions, equipment model, and buyer qualification requirements.

Parameter	Target / Typical Scope	Engineering Note
Pump interface	Pump model, rotor slot size, vane count, and original vane sample or drawing	Replacement vanes must be matched to the rotor slot and operating condition, not sold as generic graphite strips.
Vane dimensions	Length, width, thickness, radius, chamfer, groove, and edge profile by drawing	Thickness and edge geometry control sliding, sealing, and breakage risk.
Material grade	Fine-grain, resin-impregnated, or metal-impregnated graphite selected by speed, pressure, and medium	Impregnation route should match dry running, chemical exposure, and expected wear life.
Operating speed and load	RPM, vacuum level, pressure differential, duty cycle, and start-stop frequency	High speed and frequent starts can increase impact and shattering risk.
Surface finish	Sliding faces, sealing edges, chamfers, and contact surfaces finished to buyer requirement	Poor surface finish can increase wear, heat, leakage, and rotor-slot sticking.
Lot matching	Set-level dimensional and material consistency for pump maintenance kits	Mixed vane thickness or hardness within a set can shorten pump life and cause unstable vacuum performance.

Trace Impurity Review Table

Semiconductor programs should define restricted elements before sample production. The table helps procurement and process teams turn purity expectations into a measurable qualification file.

Element	Typical Limit	Why Controlled
Resin impregnation consistency	Material route defined by pump duty and medium	Impregnation controls strength, wear, self-lubrication, and chip resistance.
Hardness / density	Buyer or sample-matched acceptance boundary	Wrong hardness can wear the cylinder wall or fail before expected service interval.
Edge chips / cracks	Zero loose chips on sealing edges by visual release	Cracks and chipped edges can shatter in the rotor slot and damage the pump.
Oil / chemical compatibility	Reviewed by pumped gas, solvent, humidity, and service temperature	Graphite grade and impregnation must match the process medium and cleaning route.

RFQ Evidence Package

These records reduce ambiguity before sample approval and repeat-order release.

Vane drawing or sample report with length, width, thickness, radius, chamfer, groove, and edge profile.
Material route showing graphite grade, impregnation type, density or hardness target, and wear-risk review.
Dimensional report for thickness, sliding faces, sealing edges, and set-level matching.
Visual inspection photos for edge chips, cracks, chamfers, and contact surfaces.
Packed maintenance-kit photos with separated vanes, labels, and lot traceability.

Equipment Compatibility Review

Compatibility should be treated as an engineering review, not a catalog claim. Equipment-family language helps buyers route the RFQ, while final production still depends on drawings, samples, coating allowance, and acceptance criteria.

Equipment Family	Compatible Part Scope	Buyer Validation Required
Dry rotary vane vacuum pumps	Graphite vanes, rotor slot vane sets, maintenance kits, and sample-matched replacement parts.	Confirm pump model, vane drawing, RPM, vacuum target, duty cycle, medium, and current vane failure mode.
Compressors and dry-running sliding equipment	Self-lubricating graphite blades, strips, and wear components with tight thickness control.	Confirm pressure differential, speed, temperature, gas composition, lubrication condition, and wear target.
Industrial MRO replacement programs	Reverse-engineered graphite vanes from used samples, drawings, or pump maintenance history.	Confirm annual quantity, batch labeling, spare-kit packing, sample wear pattern, and inspection boundary.

Product Selection Logic

Decision Factor	Selection Logic	Buyer Check
Pump slot fit	Exact thickness, chamfer, and length matter more than a nominal pump model.	Send a new sample, worn sample, or measured drawing with tolerance notes.
Wear mode	Material and impregnation choice should follow the observed failure: chipping, cracking, dust, or short life.	Share operating speed, vacuum level, duty cycle, and current service interval.
Batch stability	For MRO programs, stable lot tracking matters because vanes are replaced repeatedly.	Confirm annual demand, stocking plan, and acceptance dimensions.

Manufacturing and QC Flow

Stage	Production / QC Checkpoint	Buyer Evidence
1. Sample or drawing intake	Capture exact vane dimensions, chamfer, surface finish, and pump duty.	New sample, worn sample, or measured drawing.
2. Grade matching	Select graphite grade and impregnation by wear, strength, and self-lubrication need.	Material proposal with current failure-mode notes.
3. Precision machining	Machine thickness, length, edge profile, and flatness for slot movement.	Inspection record for thickness and edge condition.
4. Fit validation	Confirm sliding fit, sealing expectation, and batch consistency.	Sample approval before repeat MRO supply.
5. Stocking plan	Align lot tracking, packaging, and annual demand for maintenance cycles.	Demand forecast and reorder trigger.

Buyer FAQ

Can you supply replacements for major pump brands?

Yes, we can manufacture dimensionally matched replacement vanes based on drawings, samples, and service requirements.

Is a pump model number enough to quote graphite vanes?

A model number helps, but a sample or measured drawing is better because vane thickness, chamfer, and slot fit control pump performance.

How do you improve vane service life?

We review operating speed, vacuum level, duty cycle, and failure mode, then select graphite grade and impregnation accordingly.

Can replacement vanes be stocked for repeat orders?

Yes. Once samples are approved, batch records and stocking plans can support repeat MRO demand.
