Correct two pumps, look back a few to mixing station pictures, you'll see the sump with a PVC line going straight up to the bench, thats a Waveline 12000.
Your closed loop would not be used for sump return, it wouldn't be a closed loop then. A closed loop is generally for flow and circulation in your tank with out having to add power heads or vortex style pumps to your DT. A CLS has no chance of back siphoning, and allows use of a low pressure-High Flow pump to provide increased flow and less power usage.
