Thanks for the link, ~gd.~gd said:Well let me assure you that the verticle drop does not have to be large ours worked best when when the water velocity was higher. Mass does not drive this pump, kinetic energy of flowing water does. maybe it would help if you knew that they are sometimes called hammer pumps because they work like the effect called water hammer in pipes. I think if you search around this site http://practicalaction.org/hydraulic-ram-pumps you will find lots of usefull stuff because Practical Action is pretty much aimed at third world problems/ ~gd
I think I've made it clear that I'm no expert on ram pumps... not even very conversant on the subject.
Well, here is an explanation from this site ( http://www.urbandanger.com/Water/Ram-Pumps.html ):
"A ram pump uses the pressure of gravity on water to pump the water uphill. It generally needs a water source with at least 5 feet (+-) of head (fall) and a minimum of 3-5 gallons per minute of flow in order to function properly. The more head or flow that you have, the faster it pumps the water."
