Animation | How ram pump works | Explained in detail.

This video is an animation based tutorial on the working of hydraulic ram pumps. We have made this video in such a way that it's very easy to understand. Have taken sincere effort to make it as simple as possible with animations and explanation.
Ram pump works with the basic working principle - the gained momentum of the flowing water due to gravity and the flapping of the two valves namely the waste valve and the delivery valves. These types of pumps are used in rural areas which have a requirement to pump up hill and the availability of power is less.

Working of the ram pump briefed:

As shown in the animation. The water from a spring is directed to the ram pump using a pipe. The water is flowing due to the gravity as the ram pump is located downhill. Due to gravity, pressure increases inside the ram pump, resulting in the water to be forced in to the pressure chamber. In the pressure chamber we have air. The water entering the pressure chamber compresses the air to the maximum limit. As the air gets compressed its releases its pressure back on the water which forces the water up hill.

The basic requirements in the area of installing a ram pump are:

1. Should have a continuous source of water from a pool or natural spring from uphill.
2. Normally used to pump water to uphill to a village or home where availability of power is limited.

Advantages of a ram pump:

1. Less moving parts so the wear and tear is limited.
2. Less sound.
3. No need of power for the function of a ram pump.

Disadvantages of a Ram pump:

1. Wastes a lot of water, when 10 percent of water is consumed the rest 90 percent is wasted.

This summarises my search for a water pump. Its the only one thing that will surely transform my land into a oasis. Thanks guys for the creation.

[AgnesMariaL]

Thank you! I have seen many diagrams and videos on ram pumps, but was unable to grasp the physics of how they worked until a friend shared me this video!

[TheLooknFeel]

This animation and "explanation" fails to explain the most important part of this entire mechanism, i.e.: how the waste valve works. It also fails to explain the function of the chamber to the right (upstream) of the pressure chamber.

[realestateinfonet]

Superb video & information! Thanks for sharing it with us!

[RealtyWebDesigners]

Kudos. Amazing how many people believe this is impossible!

[miltonbeer]

For those who doubt a ram pump functioning by only weight of water moving through the system, I have seen this type of system actually working for gold miners camping on government mining claim land for two personal friends . I can still hear the pulsation of the devices that was ongoing 24 hours a day ; unnoticeable if located far enough away, but actually was not a load noise anyhow ( click, clack ) .

[grandmaster.batumonster]

Hi.
So, how do we move stagnant water, say in a pond into the ram pump to move uphill .
Any suggestion?

[samtraji]

how the waste valve is opened at the beginning and in the process its opening to the other side? wouldnt the water just flush trough that waste valve if its opened this way?

[MrReidREad]

Thank you! New to ram pumps and after heaps of videos I finally get how it works. It should therefor work in a waterfall into swimming pool pumped back up to higher fall then yeah? I want to build one where waterfall is pool filter so hoping it will.

[steveschartner]

Will it push water higher than the source?

[mpumeleloncube]

Is there any dealer with these pumps closer to Zimbabwe?

[lyrixsu]

Just a thought, the pressure from the pressure chamber is enough to push the water even to higher location but there's still a split second delay since the pressure chamber needs to accumulate enough pressure again before it can push the water. Maybe, if you put two pressure chambers in series and they are both connected to the inlet but the 1st chambers' output is connected to the second pressure chamber which has two incoming delivery valve. That will create more pressure quickly since the pressure created from the inlet and the 1st pressure chamber will be added together to create pressure for the second chamber which is then connected to the delivery pipe. Two or more pressure chambers in series I guess can speed up the pumping of water to the delivery pipe.

Could this be what the inside of the pyramid of Giza is? A water ram pump? Is it a giant water pump tower?

[dhanasirihonduwa]

Thanks for your explanation. How much pump up this pump. Hight.?

[victoriap]

Great! But then it is not really a pump, but the dynamic of the water

[SaintMarneusCalgar]

thank you i did not understand how the wast valve work till now its so simple and so ingenius^^ i bet the guy who invented it exidentaly found this design^^

[Zappyguy]

So it converts the momentum of the in flowing water to air pressure inside the hydraulic cylinder, which then is converted back to up hill flow, once the pressure in the cylinder is equalised, the waste water valve is opened to get the momentum of the inflowing water to rise before suddenly shutting off to divert it back to the cylinder, raising the air pressure and restarting the cycle.
Rest assured, it's not free energy device as it uses the momentum of the inflowing water and discards much of it out the waste valve. Fiscally free, but not free to the scientific definition.

[yellooh]

I wonder if using multiple ones in series could work? There would be much water loss along the way but I think the water can be recycled or used to power yet another system. The possibilities are endless for parallel & series running systems.
I might have to try it out.

[ishangopalka]

Dear Sir. Good video but if the pressure lowers, then the waste valve must open inside and not outside

[sameerambekar]

Thanks, can we put the waste water back to the source?
