Pumping water with batteries

Small pump. For liquids. Battery powered. Inexpensive. Does such a thing exist?

I've been searching for pumps and haven't found much available. I've found several pumps for garden fountains, that are basically a small paddlewheel on a fast motor that flicks water. Far too inefficient for battery power.
I've found homebrewers making their own peristaltic pumps
which could be shunk down.
Any other simple homemade pump designs or sources for cheap pumps?
