The ram pump or hydraulic rams, are types of hydraulic pumps that work from the energy obtained from a tank at a certain level.
As a main drawback we can claim that suffer some loss of water while operating on water hammer.
However its strong point, in addition to its ease, is that they work without electricity, so that they can be used in remote and inaccessible places, which otherwise could not pump water to a certain height.
In the following images obtained in the wikipedia, you can see the assembly and operation diagram of a ram pump

We continue to look for interesting resources and information that allow us to make a homemade ram pump to use in any situation.
