SELF ACTING WATER
PUMP Wendy Farr - 1st post - 9 Nov 2003 17:00 Did
anyone see a feature recently concerning a new type of water pump
which is driven by water, no electricity or other power involved? If
so, can you explain how it works? I didn't see the programme myself
but would appreciate any information on this subject. [reply]

I haven't seen the programme either, but there has been a device
around for some time which does this, called a hydraulic ram. (If
you get a large scale map of the country round Stroud, you will see
some mapped - I can't confirm any there, though.)
This uses the force of water flowing along a stream or river to
pump a smaller quantity of water up to the site where it is needed.
I can't draw a diagram here, but it involves valves bobbing up and
down.

If you use a search to find out howstuffworks and hydraulic ram,
you will find a description, and if you search hydraulic ram and
animation, you will find one that shows the way the movement works.
The original was developed by the Montgolfier brothers in seventeen
hundred and something.

for Alternative Technology (CAT) and Intermediate Technology
Development Group (ITDG) would be 2 places to look for designs and
explanations.
Beside the hydraulic ram, I think there is also a tube laid on a
stream bed which uses the flow of water to push air/water around a
secondary circuit, again not that new though. [reply]

There's a similair pump run from a tap that we used to use in
chemistry - anyone know what that's called? [reply]
