Clayton Mark Deep Well Pump

[gregguy]

I purchased 2 pumps that were VERY NOS.
They look like a Midland #449.
Where might I find parts for a Clayton Mark deep well pump?
The pump has a slight manufacturing error. The flapper post is bent.
I will see if I can add pictures. (Seems to have worked)
At the very least I need a gasket.

Thanks..........greg

CM cylinders havent been built for a long time. That appears to be the bottom check? If so, most open top pump cylinders have standard pipe threads on the bottom of the barrel. Replace this check wholesale with a regular check valve threaded in to the cylinder bottom. It will work the same, you just wont be able to pull it with the plunger but they are less problematic so ease of service is not so much of an issue

I wouldn’t use a Clayton Mark windmill cylinder if you paid me a lot of money. They’re Chinese made copies of the midland cylinder. I’ve had multiple first hand reports that they don’t pump when installed at the end of a pipe string. When you test them using a bucket of water on the surface they seem to work. This was about 10 years ago so maybe production problems were occurring . I will pay more for american made Midland cylinder that I know will work.
