Leybold TRIVAC D16B Rotary Vane Vacuum Pump – Product No. 11265

Up for sale is a genuine Leybold TRIVAC D16B two-stage oil-sealed rotary vane vacuum pump. This is the single-phase 230V model (Cat. No. 11265) – the exact unit shown in all photos with every factory label fully legible.

Removed from a commercial laboratory environment (unable to verify due to power requirements). Manufactured in Germany by Leybold GmbH (Cologne) in 2018 (Fab. Date 27.2018). Serial number 31001783179 (matches both pump and motor labels). I was told it works and I have a suspicion It may have never been run because there’s zero oil in it and how clean it is… but that’s pure speculation.
