Yes, 4 main drains set on 2” all the way to the pump. Each water sheer has a single 2” ran to them.Do you have 2 separate 2" pipes that are connected to 2 separate sets of 2 main drains?
If yes, I would combine them at the pump.
The 5' elevation adds 5 feet of head loss to the suction.
For (2) 2" pipes combined carrying 120 gpm, the dynamic head loss is about 7.5 feet.
So, that's 12.5 feet total head loss for the suction.
I would use an Intelliflo XF for both sets of sheers.
