Hey guys, first post here. I have been working with composites for a couple years now doing small infusions in my garage. I mostly make small motorcycle parts. I currently work at a wind turbine manufacturer running most of the infusions on turbine blades. I think it is time for me to upgrade my vacuum pump. I dont plan on making anything too big, the biggest thing I could see myself making would be about the size of a car hood. That being said, I would like the ability to make something larger than that if needed.
I recently bought 5 vacuum pumps on Craigslist that need rebuilding for $100 total. Here is what I bought:
I got two Welch duo-seal vacuum pumps model #1402.
I also have two Edwards high vacuum pumps “Speedivac” model #ED200
And the last one I got is a Welch Duo-Seal vacuum pump model #1400
All the pumps need some work to get running. Some are better than others, although all pumps are salvagable.
I plan on building a EVS system with an automatic on/off switch so I can run the pump when needed unattended.
Which pump would you guys recommend me rebuilding for this project? Pros and Cons of each one? Thanks!
