marcar You need to power the punp with 3 V. You can use a couple of type C 1.5 V batteries in series to obtain the 3 V. If you want to power it with USB you need to reduce voltage from 5 V to 3 V using a 3 V fixed regulator or 3 silicon diodes in series between the USB power supply and the pump power leads (each diode cause a voltage dropof about 0.7 V; 2.1 V for the 3 diodes in series). I hope you can manage it with this info.
