What to look for on this family

Two-stage oil-sealed with gas-ballast. Make sure the model code ends in 'B' (= B-Variant with built-in gas-ballast valve). Check oil sight glass and that the exhaust filter is clean.

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.
