its a ratinf on how much flow they are geared for. higher number means faster flow,but less torque.

like a mtn bike

yeah sorta, the less power you have (batts), the lower head you can run without bogging to motor down and killing it

I have #5 gears for my back pumps and a #9 for my front(lay n play setup) but have only had to take apart a #5 before so i wonder, do the gears have a different amount of teeth on the different numbered gears? Anywhere to find the specs on them such as how many gallons per minute they should flow at 12v, 24v, etc?

its the length or width of the gear depending on how you look at it .. if you look at the side of the pump head the center sections width

the wider the gear the higher the number and more flow the pumps is rated for ..
the wider the gear the more volts you have to use to overcome leverage of a wider gear to get the pressure up
