Pump that runs without electricity

A pump that doesn’t need electric power to run… "Ram" or water-hammer pump.. an old design that was around before the advent of electric pumps.

I don’t quite understand this one right now, but someone out there might!

Excerpt:

"last season, it hammered over 145,600 gallons of pond water up a steep hill to our garden over 700 feet away and over 100 feet higher than the pond! In the process, it saved us over 485 liters of diesel fuel we would have normally used to drive our diesel tractor to pump and tow the water around our farm.

The pump was built for about $50 worth of plumbing parts and a bunch of stuff that I had sitting in my scrap pile."
