No there is no point to efficiency as the pump cannot work any faster than your quarry goes(it just sucks up the liquids as the quarry mining head comes by). It does require power however to work. 10MJ per source block pumped, 25MJ per frame part placed to "barrier" fluids from flowing into the quarry.So I got Silk Touch on my QuarryPlus... thanks! Another question, this time on the PumpPlus. Here is what it says in the QuarryPlus wiki:
"You can get liquids if you place it next to MiningWellPlus or QuarryPlus.
At default, liquid is volatilized in re login.
Unbreaking Enchant produce working with less energy.
Fortune enchant produce drain bigger area liquids.
Silktouch enchant produce liquid is not volatilized in re login."
Two questions - apparently "Efficiency" enchant doesn't do anything for PumpPlus? And what does the odd wording about re login mean? Basically, the PumpPlus requires no power to operate? And any liquids it collects just magically go away without us having to do anything, unless you use Silk Touch and then you can pipe the fluids to a storage tank?
And no, liquids are always stored in the pump and will be output into tanks/whatever no matter what enchants the pump has.
As for the "volatilized" I have no idea. I think it is something arisen from the fact that the Quarry+ readme seems to have been google translated to English. My best guess would be that it refers to block updates. Without silk touch VERY large pools of fluids in the quarry might then update and flood into the adjacent parts on login. But with fortune the pump will deal with pools like MFR sludge, poo etc. in one pass, so never seen it happen.
