WHAT IS HYDRAULIC RAM
PUMP?
A self-acting cyclic water pump
powered by hydropower.
Lift a small volume to a location
significantly higher than the ram
and the source of water.
It has only 2 moving parts.
CHARACTERISTIC OF A HYDRAULIC
RAM PUMP
No other external energy input.
Its operation will continue 24 hours a
day.
Only a small portion of this water
(around 25 % or less) is pumped up.
HISTORY
The hydraulic ram is a very old, and wellproven, 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).
In 1929 the company was acquired by Green
& Carter, of Winchester, Hampshire, who were
engaged in the manufacturing and installation
of the well-known Vulcan and Vacher rams.

APPLICATIONS AND LIMITATIONS OF
HYDRAULIC RAM PUMPS
 Use of a renewable energy source ensuring low running cost
 little environmental impact
 low maintenance requirement
LIMITATIONS
 Limited in hilly areas
 Volumetric efficiency is very low
CONCLUSIO
N
 Broad prospect of utilizing the country's abundant surface
water
 The cost of civil work and pipe installation, the initial investment
could be very high
