I got this pump from an old Sanborn compressor, but there are no serial numbers or model numbers on this pump. It's twin cylinder, and it has no oil site glass. It works very well.....I just don't know anything about it! Could anyone identify it, please?

Update: I found out it's a Sanborn 64BL150 , but that's all I know about it. I can't find any other information, unfortunately.

Thanks for the confirmation. Right now, I have this pump mounted to a 20 gal. Campbell Hausfield tank, but my neighbour gifted me with a 60 gal. tank that I will be switching over to. Do you see any problems with this?

Yes, I figured it would take longer to fill the larger tank, but I plan on running the pump in 3 or 4 stage intervals to not over work the pump, giving it time to cool down between stages. I use synthetic oil in the pump, as I'm a big believer in synthetic oil.
I don't use the compressor every day....it's more of a use as needed compressor. I just wanted the larger capacity tank so it wouldn't cycle as often as a smaller tank would. The air filters are checked regularly as needed, too.

Thanks very much for your quick response. Much appreciated.

Note: Ironically, the tank is made by Sanborn! I thought that was a funny coincidence.

By the way...you sent me 2 emails just now, but there was nothing in them. Just thought you'd like to know.
