Traceable assessment
How each pump is assessed
AI helps read images and listing text. The final suitability result is calculated by a fixed engineering rule using evidenced values.

- 1
Identify the item
The title and photos are checked first to confirm that the listing is a complete vacuum pump — not an accessory, spare part or pump head only.
- 2
Establish evidence
The type plate and listing provide specific facts. Manufacturer values are used only for a confirmed model; family-level values stay clearly labelled.
- 3
Compare engineering data
Pumping speed, water-vapour capacity and ultimate pressure are compared with the selected WAVE machine and the chosen safety margins.
- 4
Assess condition separately
A photo or a seller saying “runs” does not replace a vacuum test. Unknown data remain unknown and never become an automatic green recommendation.
