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:https://www.amazon.com/Gikfun-Peristaltic-Connector-Aquarium-Analytic/dp/B01IUVHB8E/ref=sr_1_1?ie=UTF8&qid=1482306910&sr=8-1&keywords=gikfu.

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