A hydraulic ram pump is a water pump powered by water. In areas where natural flows existwith a height difference of the water over a small distance, Hydraulic Ram pumps (hydraulic ram pumps) can be used to transport water to higher grounds without using electricity or fuel, by using the energy in the speed of the flow to pump a portion of the water up to a much higher level.
