Of the many things you left out of your question, the most important is that you have a ******stepper***** motor. This is not a simple DC motor. It requires specifically times pulses on its inputs, in a certain order.

You don't say what the pump was connected to inside the computer. It's important.

You know, sometimes there is someone here who has worked with your exact device and can give you information on a way that seemingly reads your mind. More often, we need sufficient information to give someone a useful answer.
When we ask questions, there's almost always a reason for them, and often they are preliminary, with their answers spurring more questions. Also, if someone misses one of the questions, we may need to ask it again.
This isn't pompous, it's the exact opposite.
Some people fail to realise when they've been given information to allow them to solve the problem. For example, in this case, the motor has been identified as a stepper motor. Googling "variable speed control for stepper motor" might yield an answer. At this point we could give more information, or the original poster could say "thanks" and go off with the information they need to solve their problem.
Sometimes, a poster takes a third approach of getting shitty with us because they don't understand. If such a poster contacts the moderators and says "sorry that was a brain fart" then we can remove the offending posts and carry on as if nothing has happened. In other cases we might need to close the thread or even ban the poster.
We prefer the first approach as it keeps this place friendly and helpful.
