Maybe this is mostly a pipe dream, but i would really like to see a pump that works indepently from a miner, and in a less "Magic" way than buildcraft pump.
The behaviour would be similar to the miner, but instead of just digging straight down, it will actively look for any liquid around the piping, when it absorbs a liquid it will replace the water source block with a drill head (I think thats how its called) and when the drill head moves to another block it will replace the block with a mining pipe (That way it will prevent water from duplicating itself). The range would be of 7x7 (Y coordinates would be until there is no more pipes left). Of course uses Mining pipes to work, and a Electric Treetap too (Similar to the insert Mining drill to start, and remove the drill to start packing the pipes).
It has space for 2-3 stacks of mining pipes and 2-3 stacks of Cells (2-3 spaces for empty cells,2-3 spaces for Liquid cells. Cant place any cells in the space designated for the liquid cells) . Compatibility with Buildcraft tanks and waterproof pipes could be added in two ways:
1- The pump can send the liquid through a water pipe or nearby tank instead of making a cell.
2- The pump can receive liquids through a water pipe to make cells from it.
Annnnnnnnnnd i dont know what else to add, i guess modules upgrades for making it work more fast or something.
