I love the idea of a ram pump, and this PDF is on the Construction of a Hydraulic Ram Pump. I have posted a Manual on Hydraulic Ram Pumps before, and included some of the best videos on Ram Pumps from my favorite Youtube Prepper Engineer777.
A ram pump uses the potential energy in flowing water to move a smaller amount of water upwards.
It is not a magic trick with unlimited potential, but within the bounds of science you can move a tremendous amount of water over time.
This pump works well, it works 24/7/365, and it works for free. You don’t have to run a pump or use electricity to get your water up to your home or barn.
It is noisy though, and it does require a good amount of flowing water coming from a height.
Using this PDF on the Construction of a Hydraulic Ram Pump and the link above to the Hydraulic Ram Pump Manual should prepare you to build and use your own ram pump, but if its not, the videos shown on the manual page will definitely explain it all to you.
This is something I want to place on my homestead, but the best site for it happens to be just across the property line.
