The drive motor moves the wheels. The pump motor pumps hydraulic fluid that is normally used to do the lifting.one question (newbie):
why do you suggest drive motor and not the pump motor??
whats the difference
The drive motor is designed to go forward and backwards, eliminating the need for a mechanical reverse. It will have 4 terminals because the way to reverse a series motor is to flip one pair of windings relative to the other pair.
The pump motor always turns the same way. So even if it's the same type and size of motor, often the two middle terminals will be continuous or connected together internally.
From what I've seen, drive motors often have fans. Pump motors do not.
Drive motors are typically larger, pump motors are typically smaller.
Pump motors tend to have a female output that the male pump plugs into, and this can be tricky to get a coupler for (take the pump too, and perform surgery on it).
And they'll be rated for different duty cycles, I think pump motors are generally not running continuously like drive motors are designed to be capable of.
You can use a pump motor if you want to, if it's the right size, if you have a mechanical reverse or you're okay doing a little surgery on it, if you take into effect the duty cycle (same as you would have to take in the duty cycle on a drive motor, it just might be a different duty cycle).
