Gravity/weight/float/waterpump

Hi,

This is not totally my idea, but it is my version of what something i did see around the forums


I made a simple gif to illustrate my version:

1. The weight of the water in the middle bucket pushes the water in the bottom cylinder up to the hose and fills the top container.
2. When the cylinder reaches the bottom a mechanical valve opens up, letting the weight water flow downwards
2A. While the water fills the cylinder and empties the weight bucket the cylinderhead (Equiped with floating foam) floats back up again.
3. When the weightbucket reaches the top the second mechanical valve opens up and fills the weightbucket again.

I Bought this pump today for 5 euro, to modify it ... Now i just need some time...

Double action pump:

I It has a removable cap, two rubber seals and the best thing: The rod is hollow and contains an in- and an outflow channel..

The weight is not going to change much. It's its pressure on the top you're dealing with and that in turn depends on the height of the liquid. So you will end up needing a setup that is higher than the feeding tube on the left if you want the tank to drop, which defeats the whole purpose.

@Broli.

I was thinking:

Because it is not a closed system, the water that leaves the hose and enters the top container does not have to be lifted anymore..

So the total weight of the full middle bucket does not have have to lift all the water at the same time! 

A bit simular as the Hero fontain, That combined with the ability of water to use as a weight, but also the power of the cylinder floating back up again in the same water...

Also it is easy to reduce height or gain weight by modifying the shape and size of the containers..   

In theory you could use 1000 liter containers , very wide  and a very small hose..  So you have a lot of pressure, it fills slow but you have a lot of pressure to overcome the height difference.
