Today, I helped Manuel Boutreur in building a prototype. An elegant pump for an elegant goal; pumping freshwater from a well. Waterlevels can be as low as 8 meters below ground level. Standard PVC parts and a very basic design make a handdriven membrane-pump. The discharge-head in our test is 8m. The pump works axially, with a stroke varying from approximately 10 to 50 centimeters. Click here and scroll down, to watch video in two parts. Enjoy!
