hydraulic ram pump
Water Pump powered by Water
For a full discription on how to build a ram pump see Low cost, low flow, home made hydraulic ram pump (no welding required) on my website.
I made this pump a few years ago, before I found plenty of water at a higher level, and it became redundent. It is made with 1" stock brass compression fittings, some inner tube for valves, a few nuts and bolts and some copper pipe, some of which was flattened to use for valve seats. It is held down onto some concrete embedded I-beam with exhaust pipe brackets, cushioned by inner tube. The supply pipe is 3/4", the delivery pipe 1/2" and the expansion chamber 1" diameter. There is a small amount of soldering involved. It pumped a little over 10% of the water a few dozen feet up, making it as efficient as commercial pumps. The small size works with the limited amount of water I have. The basic principle for building it came from a book, but I scaled it down, and made some changes, and avoided welding. The measurments were roughly calculated by rule of thumb: "that looks about right". In this picture the pump is disconnected from the pipes. It only cost a few GB Pounds for the bend and 'T's, the 1" pipe piece needed was recycled from a skip (dumpster).
