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.

Method version: 5 August 2026

  1. 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. 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. 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. 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.
