Another option is to get something like this BigNG. A regular fan controller can not handle a pump.
I am looking into Potentiometers that can handle 12v rails, these should work rather well, the only difference in using a Potentiometer other than a fan/pump controller is that a Potentiometer will always use the same amount of energy but uses resistance to control voltage to what ever it is you want to control, and I think the fan/pump controllers actually use software to control the voltage going to the pump.
