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.

Is it possible to build a sluice for an over the top water wheel? The
stream is diverted in to the sluice so it runs over the top of a bucket
wheel. This gives loads of weight to the wheel, so it can be better used to
operate quite a powerful pump.
