Just two additions I would like to see:
1. An input slot for Mining Pipe, once there is mining pipe the pump has the ability to place it and start pumping from the layer below. Maybe increase power consumption when using this.
2: Allow overclockers please!

The IC2 pump is scarily fast with Overclockers in. When there was the bug that they didn't consume fluids, I literally could fill a double chest of cells in a matter of seconds 
Used massive amounts of power though
How many overclockers exactly?
1 stack. Maybe 2. 
Though even with like 4 it's crazy fast
Wait, It's me or you said that overclockers consume fluid ?
No, there was a bug that pumps used to generate liquid in the internal tanks but not take it up in the world. You could also overclock pumps back then, so it was the fact there was no limit to the liquid supply and so the pumps could fill so many tanks or cells.
Oh, lol XD
Put the pump next to a properly-set-up miner and you have a machine that will pump in a whatever-radius-a-miner-normally-has area down to bedrock.

That used to be like that... until Thunderdark changed the pump, "breaking" the pumping algorithm. (It still works, but it is very wonky for large region - see nether).
