EMAS Handpumps

Pumps – EMAS high quantity handpump from EMAS on Vimeo.

Make your own low cost water pump (about $12) with a few pieces of PVC pipe. This is a fantastic find. Thanks to Jay, the reader who recommended it.

“All EMAS handpump designs use glass marbles and standard PVC fittings and pipes as return valves. Different pump designs are available for high pressure, high quantity, hand-powered, pedal-powered, and windmill powered. This pump design is specially designed for pumping larger quantities.”

Our goal for more than twenty years has been to provide worldwide as many people as possible with clear drinking water. We are proud to present you our association, its concept and as well its several projects and technologies. Through our web presence, we appeal to everybody interested in this subject who wants to support this project. Specially we want to address those who want to apply our technologies by themselves (see particularly: Downloads)!

  1. Assalam to emas personal, i have drill out a tube well about 2 inch diameter and about 20 feet deep and iam using the emas hand pumping mathode to build the pump. i modefide abit where iam place the first valve at above about 3 feet from upper and the place the other at foot of pump. My questian is, is it neserry to put all two valve at bottam of water level

  2. Thanks for promoting what EMAS is accomplishing. They deserve the publicity. I have massive respect for what they are doing. There are many people doing excellent work in the world, and EMAS is certainly among the best.

    I think EMAS pump construction could also become an ideal cottage industry in remote and lower income areas. (If you check back to your cottage industry post, I suggested the link to EMAS there as well, but my comments were probably inadequate in conveying the nature of the work that EMAS does.)

    The beauty of EMAS pumps as a cottage industry is that lower income people can be trained to build pumps that can be sold to nearby medium income areas.

    How many medium income gardeners would love to have a pump built and installed for their rain catchment irrigation, or their backyard well?

    The income generated by selling pumps to medium income consumers would finance the needs of the materials to build pumps for the lower income areas. No charity required. Just a good profitable business that lower income people could do for themselves to improve their own situation.

    Everybody wins.

    Not to mention the other potential uses for these pumps, they could be used to pump any fluid. Perhaps pumping ingredients in a small biodiesel plant?

    Anyone that needs a pump to move a fluid… this is a very inexpensive option.

    • I added EMAS water pumps to that appropriate technology blog post, thanks. I’m currently working on a similar top 10 cottage industry appropriate tech list. New suggestions welcome. I’m mostly evaluating the ones on that previous list for ease of construction, impact on community and potential profitability. I’ve also pulled together a blog post about EMAS ferrocement boats. That project is very well presented in their video. Coming soon.

      Cottage industries: I agree with your analysis. This is what Jerry Epps (see blog post about composting toilets) is doing — looking for select products, matching them with developing countries and then providing training and educational materials that includes small business advice. And as you know, it goes way beyond just creating jobs and making a buck. The products have a big impact on local communities. Ex: water filters that help prevent disease, etc.

  3. We’ve all heard the stats about how many people die every year from contaminated water and associated diseases. Access to clean drinking water is clearly one if not the top necessity for life. Low cost pumps like these could save millions of lives, as well as boost agricultural production that increases income and reduces hunger.
