Sorry to say that I had a medical problem and haven't gotten back to this project. Hopefully I'll get it finished by early spring (Utah) since I need it then. One problem is the delivery pipe cost, burial, and effective resistance. Although claims have been made that ram pumps can raise water 10 times the input fall, no one talks about the limiting length of the delivery pipe and how the water plug mass in the pipe interacts with the integrating pressure vessel.
Another problem is the standard expansion tank bladder fills the entire inside of the tank and doesn't work very well due to little usable air and water space when it compresses. I made an earlier version with 3" ABS pipe and a bicycle tube and it worked better until it developed an air leak from pressure pulses. Even a 2 liter plastic bottle would be more reliable than something glued together.
Any progress on the ram pump design?
