Hi Joseph-

The BLUELab team from the University of Michigan is in the process of redesigning the treadle pump – with steel cylinders and stronger support. I will publish when the new drawings become available.

Good work on this prototype. To my knowledge no one has succeeded on the market with a treadle pump with plastic cylinders because they are not durable enough. Glad to see someone is still working on this, as PVC is much easier to work with than metal. My two comments looking at your photographs and manual. First I think the cylinders are not well enough supported and will not take any abuse. Test the pump with children or teenagers:) Second I think the piping is too small diameter relative to the cylinders and the majority of your energy will be spent overcoming pipe friction, resulting in a greatly reduced flow rate.

Joe-

I copied this to the Treadle Pump team. If you don’t hear from them in a few days re-contact me here and I will do what I can to help you.

CleanPwr is serving a major non-profit agriculture organization in West Africa, who have need of a large number of snall irrigation pumps. Capacities and head have not yet been defined. They have asked for design of a solar-powered system, with which we will comply, but treadle pumps could be much more cost-effective. We have downloaded and are printing your open plans, and would like to assist them in manufacturing the U. Michigan pumps in West Africa.
With whom can we correspond to move on with this plan?

Thank you for your attention.

It is a great job. I am a design student in China. I am very interested in this project. I this my hometown is also very needed of that kind of pump. I really want to join you and do something, design for the other 90%. Could you send me the drawings of the prototype pump and other documents.
Good for you. Cheers!
