The additional data really helps!
However, I must tell you that your idea will not work because energy loss due to the friction will soon cause your system to run down and stop rotating.
There is the friction that occurs due to the rotating component. Even the most highly accurate and best rotating parts have some amount of friction. While new materials and manufacturing techniques (such as UHMW plastic and highly accurate ball bearings) have done a great deal to minimize friction of these sorts of parts, never the less, the friction has not been reduced to zero.
There is also the friction due to the water flowing through pipes in your machine. To explain, even water flowing through a pipe will generate some amount of friction work; although in this case, I would expect that the amount of energy loss due to friction will be small, it is still non-zero. To illustrate, that is why one person can easily paddle a large and fully loaded canoe when on the water, but it takes considerably more effort for that one person to drag that same canoe across the ground.
There are also other elements that would prevent it from being a perpetual motion machine such as non-uniform weight and size distribution. If the mechanism was just a bit unbalanced, then as the rotation is induced, then some amount of wobble would be induced which would rob you of the energy needed to maintain the rotation.
Finally, I have to tell you that it will take more energy to produce the water pressure necessary to induce the rotation of the device that would be produced by the rotation of the device. Even if there is a way to capture and harness 100% of the energy produced by the rotation of the mechanism (which is impossible), then that still would not be enough energy to generate the water pressure necessary due to the friction problems outline above and the fact that are not any mechanical devices which are 100% efficent.
In short, what you need to make this device work is:
Something that can function without any friction whatsoever (which is impossible), AND
Something that is perfectly made and balanced in terms of size and weight (which is also impossible), AND
Some sort of pump that is 100% efficent (which is also impossible).
Sorry, but there is just nothing like this in existence.
I think you would be better served if you gave up this idea and spent your time doing something more productive.
However, I do appreciate how you have shared your ideas.
Thanks much and care!
