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.

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

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).

Ram Pumps in the 21st 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.
