water top off relay

[fishedout]

I have a 12v power supply and would like to use this but need the right relay to turn on a maxijet 1200 as the pump. What amp rating does the relay have to be. I hope I am asking this right I have limited electrical knowledge but do have a plan

There's a few specs about a relay here at Aquahub.com (http://www.aquahub.com/store/12voltspdtrelay.html).
