    The better you describe your needs, the better help you will receive here.

    What are the electrical requirements of your pump? How accurate does your timing need to be?

    As mentioned, the timing part of your circuit can likely be accomplished using a 555 timer IC circuit. Ten minutes is a "long" time for the 555 but I think within its useful range.
