Welch 2163B01 2163B-01 BTpro Series

New for Botanical Oils processor for post-extraction purification preparation for distillation.  Welch’s BT pro vacuum pump family has the necessary flow and vacuum level to provide fast performance for your size of rotary evaporator, falling film evaporator, filtering setup, filtering tables, and purge ovens

These chemical duty PTFE diaphragm pumps are oil-free.  All 5 models are certified CSA or c-UL-us to help satisfy regulatory requirements.

The pumping action and deep vacuum comes from the movement of PTFE diaphragms within PTFE heads. All wetted services in the flow path are made of fluoroplastic making each BT pro pump highly chemically resistant. As a result, the BT pro vacuum pump series is near-zero maintenance. A cold trap placed in-line with your BT pro pump is needed if terpenes are part of the flow path.

  • High flow for faster processing
  • Deep vacuum for higher purity
  • Chemically resistant for long service interval
  • Oil-free for low maintenance


  • Rotary Evaporators and Falling Film Evaporators
  • Vacuum Purge Ovens
  • Vacuum Filtering Flask Setups, Filter Table Setups (Winterized Oil)
