Hi Saad,

Not sure whether I understand your question fully, or the particular conditions you describe. Maybe you can explain further. But under the conditions of no pumps and no pressure differences the Archimedes' screw (screwpump) comes to mind. Or the use of buckets of course ;)

Hope this helps.

Best regards,

Niels

Interesting question also for us, in the North of Chile.

Hi Saad,

The only way to pump water without energy is artesian. or, in the circumstances cited physics law does not allow it.

best for you

Yes, of course, there is another possibility. That is often mistaken as "standard artesian –confined- conditions"; I am referring to locate your deep well in an area under natural groundwater discharge conditions ie, close to the coast or on a plain. This takes advantage of the natural groundwater flow conditions: i) recharge (movement downwards); ii) transit (horizontal flow) and iii) discharge (upward-flow). Note that you should understand the nature of the flow to be developed so you can manage extraction/quality, Saludos,jjoel carrillor

As mentioned by previous people a perpetual engine (Perpetum mobile) is against basic physics. To pump water you need some form of energy.

However, there is an interesting pump invention by the frenchman Joseph Michel Montgolfier (1796) known by the name hydraulic ram pump: http://c.ymcdn.com/sites/members.echocommunity.org/resource/collection/25F7955D-C19F-44AE-AA75-18A5DFC2B980/The_Basics_of_Hydraulic_Ram_Pumps.pdf  a short url for the long linkname is http://tinyurl.com/ovjheb2

Anyhow, the function of the pump is based on using running water from a spring or a brook (Chilean mountain?). The flow of water is the power source building up pressure by intermittent stopping the flow by a intermittently closing valve. The inertia in the water flow is used to build up pressure in a container which then provides energy to force water into a water line. A system has been pumping water  from a spring to a Finnish farm house at an elevation of 30 m and at a distance of 500 meters from the spring for over 30 years: http://yle.fi/uutiset/maailman_yksinkertaisin_kone_pumppaa_vetta_ilman_sahkoa__video/7291225

The only requirement is the availability of a flow of water from a spring or stream. The hydraulic ram pump can be used to pump the water uphill using the inertia of the flowing water.

   Interesting answer, Boris. In Spanish the wáter ram pump is called "golpe de ariete", and I had been looking for information about it. Thanks. 

Thanks for all ,rely interesting answers letting me think more in this subject . I will add more discutions later on due to some trials.  

I still make my trials in the field (in my farm) and got some of the positive results  

But I need some scientific consulting as questions 

Prof Alasfoor, I often wonder which were the results you obtained under actual field conditions? could you share them? Saludos,jjoel carrillor 

 Dear , Prof. Jose :

Of course, I am pleased your post and express your opinions and suggestions to resolve the problem, and I'll tell you later and soon what worked in this subject and the problems that I've found, and try to partially resolve at least to reduce the energy consumed and thereby extract water costs, and I will try to attach some facts process I've ever done in the field .

Prof. Alasfoor, Thanks for your concern, I shall be waiting for your interesting technical related news; It would be useful should you be able to include a hydrogeological sketch within the study site  saludos,jjoel carrillor 

Prof. Saad Alasfoor,

Yes! it is now possible using Double Acting Hydraulic Ram Pump see the video of how it works. It uses minimal power to extract water from around 200ft deep water well. We have prepared a prototype of single acting ram pump as you see here and have started working on Double acting soon within 2 months from this post just looking for some funding.

Dear Mohammad;

Thank you for your uesful video.

there is a system of pumping the water up, for about 40 meters.

the system is part of the Ali Qapu Palace arcitecture which was made at the end of 16th century.

https://en.wikipedia.org/wiki/%C4%80l%C4%AB_Q%C4%81p%C5%AB

the palace is located in Isfahan, Iran

Best wishes

Yes, we can use the hydram principle but will require widening the well.
