Help Support and Requests

We are using your standards Diaphragm pumps that we got from Best Value Vacs. What is the best pump for Falling Film and Whipe Film systems?

[Pro Series 5.6CFM Corrosion Resistant Two Stage Vacuum Pump](

This is one of the pumps. Pretty standard. However - we are looking for oilless pumps and we want to achieve that next level. Does anyone have any experience with Edwards? Any help would be greatly appreciated.

WFE and FFE require different vacuum levels.

a diaphragm pump will work for your FFE, you need considerably more pump for a WFE.

have you tried Search results for 'vacuum pump recommendations' - Future4200 ?

Ive been looking at the diffusion pump…does anyone have experience with those? How does elevation affect overall vac compared to a standard pump?
