Third-party listings (Maschinensucher.de + eBay). WAVE verifies every pump before purchase. Prices and availability without guarantee.
WAVE AI estimate from photo + specs only — not a substitute for our physical pre-purchase check.
We only handle pumps that survive water vapour and reach ≤ 0.1 mbar — oil-sealed rotary vane with gas ballast, dry-scroll, dry-screw or Roots. Membrane, water-ring and claw pumps are not suitable for freeze drying.
Found a listing anywhere? Send it — free check.
eBay, Aurena, a local dealer — paste any pump listing URL and we'll review it within one business day. We tell you if it's suitable, what to negotiate, and the all-in cost (purchase + check + electrical + shipping).
