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?

I use the Amazon Zeny Pumps. I was hesitant thinking I wouldn’t get many runs out of it, buts it been holding up. And it’s only like 80 bucks.

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.

Sounds like your bench is similar to mine, but I have a designated bench area for my fume hood where I do my boil downs. And a spot on the bench where I set up my vacuum pump. And my main workbench is where I do all my prep and seedlings and planting of other plants.
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)

They are easy to repair and maintain.
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.
