Searching long ago for something like this!
Thank you so much for your nice mods!

Hope you do tier-3 of this pump with modules support and remove modules from tier-2.
Best regards and keep youself safe!

With advanced circuits or processors?

I think advanced circuits are enough. So i make some https://pastebin.com/c62H5TPc and remove module support from electric pump.
But last word is yours ofc)

I think that some uranium pellets without burnt_result will be a nice option for the nuclear stage.
Just another electric pump is too easy for me.

The uranium pellet:
Ingredients:
1x Uranium fuel cell
2x Advanced circuit
4x Steel plate

Results:
1x Used up uranium fuel cell
1x Uranium pellet

So, such fuel has no waste after the burning and the water offshore pump can be powerful enough. For example, 120 fluids per tick?

Also my suggestion is to add T1 to T2 recipe and T2 to T3 recipe.
Also enable allow to replace each other by placing one on another.
Thanks again for your mod.
