First generation sump pump..I think...
This is in that 1846 Long Island Farmhouse...name on it is "Pernathy" ? Mad Dog

It is just a bang that says "unsafe" if you hover over it. I want to see since I have seen some pedestal pump that look to be from around the dawn of the availability of electric motors.

You mean "Penberthy"? They still make them:

Yes, I think they invented the sump pump. If they didn't, they were certainly one of the first in the game.
PENBERTHY
But I don't think they became a thing until the mid 1900s, maybe early 1900s but it doesn't seem like it.
The earliest stuff I've seen on a remotely modern looking sump pump is 1950s.

Right, @Mad Dog_2 . That looks like a jet pump. It is descended from Penberthy injectors, which were used to feed water to steam locomotive and other high-pressure boilers when they were under enough pressure that a regular pump or water service would not work. Go to any American railroad museum where they have steam locomotives and you'll probably see one.
In this application you'd need something under pressure to operate the jet. This could be steam or water. I bet compressed air would probably work too.
I wonder if we could use or modify a Penberthy jet to add vacuum back to a Paul or similar system?

Interesting, but could we really expect something from Harbor Freight to stand up to the demands of a heating system?

I wouldn't use that vacuum pump on anything refrigeration related.
It looks like they claim it'll do 28.3" of mercury, or 40,000 microns. We're supposed to pull below 500 microns in refrigeration, I usually aim for 100-200.
I have a compressed air vacuum generator made by Gast I use for vacuum tables at the shop that works well but it's loud and uses a lot of air. I think 12 CFM the entire time it's in use. I'm sure it would hold up, but doubt it's remotely practical for such an application like a steam system. Still not remotely good for refrigeration work either.

I dint' say it was a good idea, but you could make a vacuum with compressed air. When I looked at those before i knew much of anything about refrigeration about 15 years ago the consensus seemed to be they could pull enough of a vacuum to remove the air but not the moisture.

How much vacuum would one need? @Pumpguy , what are your thoughts?

It is enough vacuum, it is more the amount of compressed air you need that is the concern.

It almost looks like a venturi water pump...It's pre-1910 I'd think from the looks of it..All Galvanized. Mad Dog
