Yes.......One of the best things about this is the stream you use to get the water and power the system remains largely unaffected.

Its actually not that complicated. the key to it all is the spring operated flap valve - how strong the spring is and its range of travel.
Water flows down a feed pipe, building up kinetic energy.
When it is travelling fast enough, it carries the flap valve with it and slams shut
This sudden stop builds a pressure pulse within the water - which momentarily flows through a second NRV (non-return-valve) - into a second chamber and away up a delivery pipe to wherever you want to use it
With the water now at a stand-still, the spring can overcome the pressure of the water in the feed pipe and open, allowing water to begin flowing again.
The cycle is continuous and I seem to recall that 60 to 100 beats per minute are the most efficient.
Still trying to find my video, but Photobucket is having a hissy fit!

Edited to answer your query correctly
The flow of water out of the valve, serves to build the flow (with associated kinetic energy) and, when the valve slams shut, creates the spike in pressure that you use to pump the water to a higher head - sealing the flap valve serves only to turn the machine into a large siphon which is hindered by the internal valves.

Accidentally hit google translate. Tell me, what do you plan to do with this water sheep?

Surprised that these seem so new to people, first mention for me was in one of the Punchbowl Farm children's novels by Monica Edwards. We knew them as force pumps.
Had a sad person who used to come into where I worked who had "invented" such a pump that was going to make his fortune, he couldn't be convinced that his discovery had been known and used for many years.

Hmmm seems that Photobucket have deleted my video and said that I did it!
Wasn't all that exciting but it should the thing slopping water and pumping a jet about 10 feet above my head!
Guess I'll have to get it running again - and wait till the stream has enough water to use!

The main one I remember was Blakes Hydro Ram. Pretty sure they were invented in Napoleonic France?
IIRC the first ones used the flow of water to push a cannonball in a pipe, the last inch of movement of the cannonball pushed water up the pipe at very high pressure through a non return valve up a hill.
Used to be on isolated farms just clunking away for years with very little maintenance and when I was a nipper Blue Peter did a water for Africa/India/wherever it was project where they supplied them.
Something like a 1 litre pushed up the pipe from every ten that goes through the outflow.
Masses on Youtube and several build it yourself projects on the internet that last time I looked

Boing...
Just saw something about a Bunyip pump on Youtube and unline the rest this ones self priming. That makes quite a difference to the maintenance required to keep them going, dunno about cost though as I've looked on the website and cant find the price.

This is definitely a blast from the past!
Six years in I’m definitely more capable and tooled up to make one but still too many other projects to do.
We have an old Hydram but the replacement parts are very expensive. I'm considering replacing it with one of these:

Papa Ram Pump - pumps water using no fuels or electricity -
The Papa Water Pump is a Zero Energy hydraulic ram pump that delivers water from a natural flowing water source without the need for electricity or fuel

I came across this hydraulic ram design which looks easier and cheaper to build. Just posting in this old thread in case anyone is interested.
