Has anyone considered re-purposing a mechanical water pump off an engine? The have a pretty good flow rate. The older ones off things like GM 350s would be quite easy to mod I would think.

Not hard to build a pump at all. look up Ctsephon or Hero of Alexandria. If you've ever seen an old horse drawn fire pump that's it. Archimedes screw is simple, wrap a hose screw fashion around a frame, a barrel works well. put it at something less than 15 degrees from horizontal and turn it so the immersed end gulps up water.  A simple force pump can be made by joining several lengths of pipe with check valves. Use a larger diameter pipe as a guide, plunge the first pipe up and down until water comes out.

I wonder if you could power a centrifugal type with a bicycle.

But the Money Maker is pretty hard to beat if you are looking for a pump at less than $40

to move a volume of water quickly and efficiently there's always the treadle pump !

There's always the force pump, which is a bicycle pump with some valves.

I think they'd be easier to build than the screw for an archimedean pump.

There is just something about the archim. screw that I really like.  Someday maybe I'll figure that out and move on.

I know what you mean - but I really don't fancy making the screw bit !

Archimedes screw on of the simplest water pumps to make.  Very easy to make the size you need and easy to run by mechanical means only.

Here's the link.
