Has anyone converted from wet rotary vane vacuum pumps to dry scroll vacuum pumps?
Although we love to sell vacuum pump oil we know that botanical extraction is very hard on the internals of the pumps, possible contamination from oil mist and maintaining consistent vacuum levels. These are some of the reasons we are getting more inquiries for “dry” scroll pumps.
What are your thoughts on the Cost/Benefit of dry pumps versus “wet” dual stage rotary vane pumps? Which dry or wet models have worked or failed in your process?
We have actively sold Edwards, Agilent, Pfeiffer, Leybold and Anest Iwata in other industries with similar demands against particulate and moisture. They tend to work well but are much more money upfront and have a different service schedule to follow.
Going to a dry pump seems to be on many peoples short list of upgrades for the future. What are your thoughts?
