Does this look like it would be ok?

I looked online for specs and can't find any so I was thinking of trying to contact the manufacturer to find out the Max and/or working PSI for this model. Would you guys be concerned about the rust on the cover? Do you know if that mixer can be easily removed? The price isn't bad considering how much it would cost me to have one shipped here.

I believe it's the one listed on this catalog page, but they don't say much about it. Catalog - Asturo HVLP spray guns, Air assisted airless pumps, and more

Any advice would be appreciated. I have been keeping an eye out in Kijiji classifieds for a while now and this is the first one that has come up.

I called the manufacturer and it's rated to 80LBS max PSI and while the mixer is removeable, they do not have anything to plug the hole and it is not threaded or anything... So I'm not sure how I could plug it.

Once I mentioned to the guy on the phone that I was going to buy a used one, his tone changed instantly... It was kinda funny.

Thread the hole with a pipe thread and screw a plug or pressure relief valve in.
