What It does
The Hydraulic Ram Water Pump can lift water 500 ft from a river to a reservoir for crop irrigation.
Developed first by Montgolfier brothers, the hydraulic ram pump is an automatic pumping system which uses the energy from a small fall of water to lift a fraction of the supply water to a much higher elevation. Or to put it in other words, it uses a large volume of water through a small head to lift a small volume of water to a higher head.One of the biggest advantages of the Hydraulic Ram pump is the fact that it barely has any moving parts. The only moving parts are valves, which makes this kind of pump mechanically pump. This simplicity results in high reliability, minimum maintenance, and a long pump life. Another advantage of this kind of pump is that it usually runs 24/7with a constant flow of water. As long as the water is coming into the pump, the water being pumped out will remain constant. The Hydraulic Ram pump takes advantage of a phenomenon called "water hammer". When looking at most other pumps, they are designed to prevent this phenomenon from occurring, however with the Hydraulic Ram pump this occurrence is welcomed.
