Water pumping

All other processes depend or benefit either from water descending from a higher elevation or some pressurized plumbing system.

The ancient concept of the aqueduct took simple and eloquent advantage of maintaining elevation of water for as long and far a distance as possible.

The coil pump, if fitted with a suitable rotating seal, can deliver water to a greater height, typically 5-10m, above their discharge opening.

The outlet pipe is fixed to a water wheel, engine or animal which is capable of rotating the pump quickly.

This is possible as all the components can be built from local resources such as sheet metal bent into the desired form with or without machine tools.

The first published description and mechanical analysis was written by JH Ziegler twenty years later, in 1766, with Wirz' consent.

[4] Wirz' original pump was powered by a stream wheel in the Limmat river, to raise water for a dye house.
