Hi Speedbound,

In the boiler section of this forum you will find my small boiler project. I had to build a pump to test said boiler. This link will take you to the right page.

You will find plans and photographs there that should help.

Cheers

Rich's version of a pump utilizes "O" rings to seal the valves and main plunger stem as opposed to merely steel balls as clack valves, which there is nothing wrong with but getting a steel ball to seat well can be a real pain sometimes. I'd like to build them both as there are features I like on either one.
