DWC and aeroponics need help with research

Ok I am thinking of adding aeroponics to my DWC setup. I was gonna use a 10 gallon storage tote with 8 gallons of water. After thinking about it I am considering more like 4-5 gallons of water w/ a pump submerged that is connected to an aeroponics sprayer. I think that this will work very well but I am not to sure what I need. I don't want to buy a pump that is too powerful and bursts the lines. Also I don't want one that is too weak and lacks pressure coming out of the sprayer. I plan to use say 1/2" ID PVC pipe and 360* sprayer jets. I still need a pump and the knowledge to keep it up and running. Thanks a lot for your help fellas
