The liquid-pump/motor is a miniature one from ebay with its operating voltage rated as "6-12V".
Even at 6V (the minimum of that specified range), it's pumping liquid too fast for my requirement.
Will there be any problem if I instead supply just 1 V or 2 V (assume long-term usage) so as to reduce the pumping power?
If that is not the recommended approach to reduce the pump's motor speed, what other method should I use?
I'd like to avoid using a different pump, because this one has dimensions just small enough for my application.
