Will be finally getting around to doing my RAM Pump project soon. Just been getting the parts and assembling them. Some PVC parts will be obtained overseas though. Hopefully with this water can be pushed up the hill without electricity requirements etc.
I look forward to your progress. This tech is quite old and well proven, so I have no doubt you can pull it off. What has to come from overseas? The gate valves?
The Quarter Turn Valve and the Gate Valves are easier to source at the remote area trading stores. PVC pipe is much more abundant.
Here is an inexpensive ramp pump.... nor sure how it would hold up tbh. How to build a Hydraulic Ram Pump
