At the risk of sounding like an advertising bot: Mekanism's Ultimate Mechanical Pipes move liquids at a rate of 6400 mB/t. If my knowledge of the numbers of correct, that's the output of 128 Aqueous Accumulators. I'm not sure about how much Mekanism's electrical pump generates, but it requires a far less compact setup than an XU transfer node. What I usually do: I use a transfer node to pump water into a nearby tank, and then use other mods' pipes to move the water where it needs to be. Alternatively, I store water in my ME network. Extra Cells' fluid export buses are really fast if upgraded.
Unfortunately, Extra Cells didn't make Infinity. I miss it dearly. Same with Mek - no Infinity. I'm not in a position to add mods, nor do I think I would this deep into our world.
I'm exploring alternative methods currently...
