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 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).
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

CONCLUSION
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
