How-to Secure pump in my sump?

[awol]

My tank is still dry and I'm working on putting my sump together. However, I have a 2400GPH mag-drive pump that has no feet or anything on it to secure it to anything. How do I secure it to the bottom of my sump to prevent it from moving around and vibrating to make noise? I've heard suction cups aren't so great.
I have a 55g glass tank as my sump.

If you are going to used hard pvc as your return pipe you do not need to secure it. It will move very little with the hard pvc. Before I switched to out of the sump pumps I used a mag 24 and mag 36 in sumps with hard pvc and they did not move at all.

None of my pumps are secured and I use flex hose and haven't noticed them moving or vibrating.
