You need a lithium ion based circuit to turn on and off a 5V pump, Guess what that you are in big luck. As recently I have designed a PCB for Esforge company to charge li-Po battery, so your requirement is 90% matching to it. Feel free to contact me and I can send you samples of my work on Lithium battery charger based circuit.
