2. What is a Hydraulic Ram? The hydraulic ram pump may be defined as a self-acting device that uses the energy of a large volume of water falling from a higher location and passing through it, to lift a small volume to a location significantly higher than the ram and the source of water.

3. Characteristics of a Hydraulic Ram Water-Lifting System There is no other external energy input Water has to come from a location higher than the ram Only a small portion of this water (around 25 % or ( less) is pumped up, the remainder passing out of the ram and must be drained to a lower location The vertical distance to which water can be pumped up from the ram is significantly higher than the vertical distance from its source to the ram

4. History The hydraulic ram is a very old, and well proven, technology for lifting water. In 1772, Englishman John Whitehurst invented a manually-operated precursor of the hydraulic ram called the "pulsation engine." The first one he installed in 1775 raised water to a height of 16 ft. (4.9 m). The first self-acting ram pump was invented by the Frenchman Joseph Michel Montgolfier in 1796 for raising water in his paper mill (Montgolfier is more popularly known for his work in hot-air balloons).

5. Ram Pumps in the 21 st century In recent years there has been a resurgence of interest in hydraulic rams, particularly in developing countries, due to the continuing rise in fossil-fuel prices. In India, Vietnam, and China their governments are very active in constructing hydraulic ram systems and in disseminating the technology to the countryside for irrigation and drinking water (a German group is leading the effort in Vietnam and China). In Africa (Zimbabwe), a British group has been active in this field since 1994.
