Nice little gear pump, no metal inside parts, easy to clean. Only one nipple, for hose, second (on lid) is a sharp pointed steel needle, 1.6mm outside diameter, like on a big syringe. I ordered 3 and all are the same. I wonder what is the original use for them? And for continuous running, I would not put more than 6V on them, even on 6V they get hot.
