I am in need of a very small, cheap water circulating pump that can run continuous. A brush DC might be an issue though. Est life cycle is 10,000hrs but probably will never touch that. I know of BLDC motors but I would rather run this device on straight DC power to simplify my life. I guess if I could find a cheap AC pump, I could do that too.
I have found some little BLDC pumps for use as PC coolers but not sure if they need a controller.
