Arduino water pump

Hi, I want to drive an arduino water pump to simply pump water.However, i have no idea how to make the circuit for it.I know that the arduino only supplies 5V but the water pump I need to drive is 12V.

This is the pump I want to drive:

If the pump will only run in one direction, you can use a common NPN transistor with the proper current rating, such as 2N2222A.
