campbell hausfeld pump ID needed

[bobcatman]

I am trying to ID an older Speedaire/Campbell compressor pump so that I can order new flapper valves for it. It may be an old Sears compressor unit altho there isn't any ID left on the tank. It uses a ribbed flat belt and has a twin cylinder vertical pump. The pump has a #3 cast into the lower area, and, from the best I can read them, the numbers G0168 cast into the side of the pump. I have attached a pic of a pump like mine. I need to know what flapper valve kit to order. There are 4 valves (2 thin valves and 2 retainers) under the plate on top of the head and 4 more valves on lower area of the head in the cylinder. Any help would be greatly appreciated!

That is the ubiquitous "VT" series pump. Made for decades in various forms.

CH has parts manuals/parts lists online under "service and support". Put "VT" in the "find model" search box and you will get an extensive list.

Mine happens to be a "VT611900" pump circa 1983. It seems to be like what is in your photo. Put that in the search box and you will get the link to the parts list. Also it will show links to valve replacement instructions.
