Hi sharma,

Can you give me a little more information? Why do you want to replace a vacuum ejector?

Typically, I found vacuum feeds to be more reliable as there are no moving parts.

Thanks for helping me understand your specific scenario.

I can suggest you the supplier of dry motor driven pump for vacuum replacing ejectors.
You can let me know your location then I can give you contact details.
Also you can go thru my comparison on ejector vs pump for vacuum on my blog Chemical Professionals at
