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.

PROCESS

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
