Ram Water Pump

thingiverse

This is a Ram Pump, which uses liquid pressure behind it to push water uphill or to a higher location without electricity or mechanical aids. A more detailed description of how the pump operates can be found here: https://www.youtube.com/watch?v=aUTjVovpKvA&t=9s. A similarly sized ram pump build and test using shop-bought parts can be found here: https://www.youtube.com/watch?v=uMMQx5Nfi_U. Notes: - A toothpick or similar small thin stick is needed to fix the hinge inside the valve. - I have not tried actually pumping water with this design; however, it is useful to learn about how the mechanism works.
