Trying to find rings for this older compressor

I don't have much info, but I know this is a single stage, 2 cylinder, pump.


I am helping my uncle from a few hundred miles away, and he can't find any other numbers, letters, or data plates aside from the picture of the B's ?

He thought it was a speedaire, but I'm not so sure. I'm having zero luck finding rings by size. I can't even find the size of rings in the "details" for the models that look close.

Any ideas what make/model this might be, or even just where I can get a set of rings (2 compression, 1 oil) that measure measure 3.19" x 3.42" x .1220".

Jerry, I called hastingspistonrings and they were super helpful. I still have no idea what model this pump is, but the rings are not an "available" size, so they recommended having a machinist trim them down, or bore the cylinders out to make something fit.

Apparently, this pump has no parts available so it’s either Frankenstein it, or junk it.

That’s my experience with this one.

Hope you have better luck.

I think we have the same pump and issue
by: Jerry

I posted yesterday with the 4 cylinder that has no name or model on it, my pump has the same markings as yours

Brunner

This is a Brunner, although without the metal tag attached to it, it will be hard to figure out which model.

Have you tried

Those dimensions don't seem to be standard, but you can probably round up or maybe down a bit to find something.

Good luck.
