Making a centrifuge(?) to pump water?
Ive never heard of an impeller or known anymore than the name of a centrifuge so have no idea, although obviously have basic theoretics devised from reading other instructables.
What I am looking to create a DIY pump for 5 litre bottles of water. First prototype, I plan to just have a dispenser where you hold a lever (as in a finger length one, as on water coolers) but then I plan to build it up with cooling and mabye building a unit where I can hook up multiple bottles for an extended, no hassle supply. Obvioulsy I intend it all to be motor powered, although If you have knowledge on a manual pump as a backup system, that would be interesting to learn about.
