If you're wanting only one connection face and need to transfer faster than a liquiduct can output, GregTech's machine box with a pump module can move (I believe) 20 buckets per tick. It can get expensive at longer distances, but you could probably attach 3+ liquiduct outputs to a machine box with a pump module outputting to whatever machine you're dumping steam into, so you still have all your other machine faces open for automation purposes.
