Title says it all. I am looking for a submersible water pump, a few
litres an hour would do, driven by propeller/turbine working off the flow
in the stream to pump water up a few feet. Or of course any relevant
components of this idea would be useful. Many thanks for your thoughts.
Water wheel, unless on a raft, is no use as water lever varies about 5000%
of minimum 100mm or so.

Sir might want to look at this old, but effective concept

Sir may also like to get some ear defenders if he uses one...
