Design Outreach (DO) developed a new hand pump called the LifePumpTM to alleviate the depth limitations and reliability issues of commonly used standard hand pumps. In partnership with World Vision and The Collaboratory at Messiah College, Design Outreach piloted its LifePump in five African countries, beginning in November 2013. Researchers at Messiah College independently evaluated the LifePump pilot in order to study its field and laboratory performance. The LifePump operates at twice the depth of (up to 100 meters) and requires much less maintenance than standard hand pumps. The design is less prone to sudden failures than standard hand pumps due to its progressive cavity pumping element and heavy-duty components. Additionally, select LifePumps are equipped with SonSet Solutions’ remote satellite monitoring technology that transmits information on pump performance to DO so that it can be monitored via the web. This paper describes the LifePump technology as well as the pilot project context, activities, and implementation strategy.
Here is another article on the LifePumpTM from Bixler and his colleagues:
Just what we need - another quality, durable, hand pump. I am not being sarcastic.
