This ram is using the flow of my little creek to pump water up to a tank behind my shed. I was pretty impressed with just how well it works.
The feed pipe is about 12m long, then a stand pipe to remove bubbles, etc. Drive pipe is 9m. Feed and drive are 40mm PVC. About 1.2m of head feeding the pump.
Fills the 500l tank overnight, so I get about 1000l per day ( 250 gal ).
Thanks for watching.
