i want to know if an Archimedes screw pump is more eficent that a modern screw pump to elevete clean waters 4 meters i saw many modern screw pumps smaller and want to now about the efcency of ths two types.

    Does Archimedes still sell them? – Solar Mike Sep 06 '20 at 13:47
  • If Archimedes was the most efficient method and any patent is expired, why would this pump exist? – StainlessSteelRat Sep 06 '20 at 16:43
  • totally different beast from an Archimedes (or auger pump. ) Is is this a pressuer pipe application or are both water levels free (open to air)? What is the approximate flowrate? Much variation in this flowrate? – mart Sep 07 '20 at 06:18
  • this is an explanation of an archimed pump: https://engineering.stackexchange.com/questions/1958/what-makes-the-material-travel-through-archimedes-screw/1960#1960 – mart Sep 07 '20 at 06:19
  • good help thancs – gusgus Sep 08 '20 at 18:53
  • the point s that need to irrgate 150 hectars on a border of a river for alfalfa and corn production. thaugt an archmedes screw pump because need to elevete 3 or 4 meters no more prhaps les than 3 meters m wanted an archmedean one but an small one s dificult to get and transport. y wanted to do t whith zinc n an menonte or amsh colony that s near they are good in handcraft but construccon is complicate am thnng what to do – gusgus Sep 08 '20 at 19:06
  • What's the flow rate and setup of the irrigation system? – mart Sep 08 '20 at 19:18
  • well the land is rented for 2 years for natural cattle breeding its too difucult that the man who rent an another breeeders use water for doing pasture. the land is dry rain are near 300 a year bur you can tae water from the rivers the rver name is colorado just the border of patagona the land has a peninsula le a shape then you can tae the water in dferent points have more than 2500 meters of cost on the river. – gusgus Sep 10 '20 at 11:57
  • to produce alfalfa for a pasture mix wth clover and a type of rye grass youll need n summer more water for each harvest s about 10 a year wth water s to mae straw bales to sell to others farmer in dry tmes. f you do alfalfa for seed production a fre lcense one is less water and cor need a moderate water rate. – gusgus Sep 10 '20 at 12:10
  • but d id not mae calculus yet and the sistem wll be wth a canyon at frst wll began in two years. but the rate flow wll be a complex calculus and at frs have to see de levels of the land exactly . is plane n general baut for the water a mnmun dfference s a lot. thans for your nterest. am thnng at frst n water supply. cost and then what really to do. – gusgus Sep 10 '20 at 12:10

That looks like a Moyno, The rubber stator or shell makes it dramatically more efficient than a basic Archimedes type. Moynos develop significant pressure which is not possible in Archimedes.

I did a reverse image search, and it seems -- like blacksmith37 said -- that it's a progressive cavity Mono™ pump (or MOYNO™ for the Americas [no citation]). This is most likely where the image came from, and here are the specifics for that pump. Apparently, it specializes in viscous and chunky fluids. It seems pretty nice to me, but then again I'm not a pump expert.

My guess is that because it is an all-purpose, chunky-fluid, non-clogging pipe, it may be less power-efficient (or, more likely, less power-efficient per cost, as it may be more expensive) than the best models for clean water because of its generality. I don't know what screw pumps you're looking at, but if they're smaller and cheaper than this and will work just as well in clean water, then go for it. And besides, any energy inefficiency is just a drop in the bucket of our bulky SUVs, Stirling engines, and burning oil wells.

Oh, and if I made a mistake, or you have more information, please comment! Thank you!
