Humm, interesting question. Do you have the same pump currently in a 12V version? If so, I'd try measuring the resistance across the power leads and compare. The measurement needs to be done with at least one of the leads disconnected from anything else to ensure you aren't also measuring something else that's attached. If it's a 24V pump, I'd expect the resistance to be double the 12V's resistance. But that assumes all the impedance of the motor is resistive, and I'm not certain that's the case. My knowledge of motors is weak enough to be unsure. Hopefully someone else will know more.
