I would like a vacuum pump to use for vacuum filtration and vacuum concentrating extracts. In the old days I would have used a water aspirator for this. A chemical resistant diaphragm pump would also do. Looking on Amazon for a pump I see only imports of unknown brands. Can anyone recommend where to look to find good and suitable pump?

Thanks. Yeah, at that price a pump like that is worth a try, I looked in the catalog of a large industrial hardware company and a similar pump there was many hundreds of dollars.
Or, perhaps I will go the water aspirator route. A water aspirator is what I used to use for solvent stripping and vacuum filtration once upon a time. My work bench is in my greenhouse, I have running water and power but I would use a recirculating pump and water bucket to power the aspirator.

Always battling sqft’age, but thank god i have the space in my basement in the first place. Could always be worse. Haha.
The reviews on that Zeny pump are mixed as in people have gotten only 1 use. And reviews like me where it’s been holding up. (Personally I think the bad reviews are user error)

Simple stainless steel Reed valves under the cover. Susceptible to hard water lime and calcium build up. Some CLR solution and a soft toothbrush gets them clean and then a little silicon grease to keep them clean. Don't be afraid to pop the cover and look when performance degrades.
