ZeroBorg can handle an absolute maximum of 10.8V for the power input. The voltage that is output is limited by the input voltage, so this means the highest voltage it can possibly deliver to the motor outputs is also 10.8V in this case.
Depending on the pumps they may or may not work at lower voltages. Usually the voltage stated on motors / pumps is the intended operating voltage, meaning they will often work at lower voltages with a reduced power output.
My guess is they would operate with a 9V supply at a reduced pumping rate, but I cannot be certain. 10V supplies are unusual, but 9V supplies are fairly common. The easiest way to check would be to try powering one of the pumps with a 9V supply directly and see if it runs properly / fast enough.
