1945 dated using the serial number! oops! i thought i had the original manual guess not. bought by my great grandfather to run the vacuume pump for the milking machine in the cow barn! just needs a tune up and it will start and run better! 2hp 1500 rpm flywheel 750rpm camshaft in this video i have it belted to my smaller Early goulds hi-speed piston pump which i restored a few years ago. i also have a bigger version of this pump! it can build up more pressure and shoot water farther than i show it! i have actually blown the relife valve on the font of the pump before! be sure to visit my channel for more cool vids!
