Diaphragm pump unsuitable as primary vacuum source for WAVE freeze dryers.
Condition from photo
Exterior clean, no visible oil leaks or damage. Aluminum heat sink and red housing intact. Labels legible.
Watch out for
- Diaphragm pump: designed for mass spectrometer backing, not freeze-dryer primary
- No ultimate vacuum specification provided; typical diaphragm pumps reach only ~0
- Pump type mismatch: WAVE freeze dryers require rotary vane or rotary piston pump

What to look for on this family
Generic Pfeiffer vacuum pump — the exact model family was not detected automatically. Suitability remains unverified until the model or type plate is clear.
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.
