Folk Hydraulic Ram Pump
Use the energy of flowing water to move water just about anywhere. We have harnessed a spring on our property and have used a ram pump to pump a continuous flow of water between 1.5 - 4.5 gpm up a rise of over 200 ft with nearly 1000 LnFt of run (in 200psi 1" poly pipe). Amazing!! And it's been running now for nearly 2 decades (installed 2003) with virtually no problems. Our biggest issue has been wanting to continually improve the overall system.
Our newest (summer 09) modification. First you'll notice the green 3" feed line (flex irrigation pipe) coming from the collection basin. This feeds the self-cleaning filter (a simple box with a screen for the best explanation see the video). This is sitting on top of one of our earlier improvements. Another Rubbermaid trash can. It is used to provide a back shock cushion between the drive line and the collection basin. It has been flexing with each pulse now for 4 yrs. The pulsating of this tank is what allows the self-cleaning filter to work. With each pulse in flows back through the screen and washes away any collected debris. Again, see the video.
Slice of tire sidewall makes the best washer for the constant bouncing of the flapper valve. Can't believe it took me nearly five years of cutting out pieces of various types of rubber gasket to figure this one out. Duhhh!
Haven't had to replace this one for several months now, and it's not showing any signs of wear.

Hacking our ram pump
New backup pump
self-clearing input screen filter
backside water flow into main collection tank. Filter screening installed since this picture ~2022
Pump in actions
tank pressure with 200' head
supply tank with overflow pipe. Feed pipe to ram is the green one at the bottom
rubber tire piece for damper gasket
drive pipe covered with straw and plastic
self-cleaning filter set up
power box for future use
excess drive water flowing out of pump house
pump house sitting on concrete base
storage tank connecting lines
valves for shutting down 2 tanks in the winter
Four 2,500 gal poly tanks, wrapped with insulation. Gravity feed to houses
Water storage house
Water lines labeled, Note: pressure sensor added to 2" pipe at the "connection to other tanks"
Arduino box with ESP8266 module for monitoring sensors:
Ultra Sonic for water lever, Pressure for backup water lever, flow meter for pump running check
Analog guage test reading at pressure sensor installation point.
verifies pressure at ~8psi 58degF
