FASCO / Cole Parmer Diaphragm Pump. 115V@60Hz, 1.1A. Model 71637137, Type U63B1, P/N D-1728. I do not see a Cole Parmer logo or model number on the pump head, but it has a Cole Parmer patent number on it.
Pump worked and sounded good before removal. This was installed inside machinery, so it is very clean as you can see.
