Well I have a single tier with two pumps, but starting out you'll use one pump and swap it between jobs.
Or, you can build a two tier system with a single pump.
I suggest quick disconnects like the ones from morebeer.com if you have to switch the pump around.
You would get your water to strike temp, pump it up to the mash tun and mash in.
You can use the pump to vourlof or get a HERMS coil and recirculate it during the mash.
Then you can gravity feed your wort to the boil kettle while you pump your sparge water to the mash tun for batch or fly sparging.
Once your boil is done, you can use the pump to run your wort through you're chiller to the keg. Or pump it right to the keg if you're using an immersion chiller.
Here's a youtube video showing a simple setup that uses a pump and a HERMS coil.
Just remember that you have to use a specific type of pump. It needs to be high temp and food grade. Chugger and March pumps are the common ones used in brewing.
