Old air compressor

I have an old air compressor pump that I would like to know the model and who manufactured the pump.


There are no markings on the tank or pump and the electric motor is missing.

These pictures I found are identical to what I have.

The cylinder is in good shape and it pumps air when turning by hand. I am trying to determine the proper pump rpms and was curious if parts are still available.

That's very cool. I have wondered why there's usually a dash...

Thanks for the tip - there are lists out there...

3 digit number on compressor pump?
by: Paula

If the pictured one has a model number, the first 3 numbers are the manufacturer. Sears uses many different ones.

So the bore /stroke is about 7cu in, or about 250 revs for a cubic foot. At 1000 rpm, about 4CFM.

So, I think I'd go with a 1 or maybe 1.5 HP 1750rpm motor with a 4 inch pulley for 900RPM, which ought to get something over 3CFM output. The 4 inch pulley looks about right from your photo.

You're free to do your own, of course...

This is a very old Campbell Hausfeld pump. I doubt parts will be easy to find.

Just looking at the pic, if that motor is 1750rpm, then the pulleys look like you'd be close to 1000rpm, which is reasonable. And from the look of the pump, I'd guess 1 or maybe two HP for it.

If you can get ballpark close to the bore and stroke of the pump, we can make a somewhat more accurate guesstimate.

May as well give the pump sheave diameter, too.
