Can anyone come up with a good reason to use 2 condenser water pumps for each unit (on supply and return) on a water source heat pump system (geothermal)?

Try to select a pump and see what kind of efficiency you will get. Low flow/high head application territory, reduce the head for a better, more efficient pump.

No, it is not my design. I would use a main circulating pump and primary-secondary pumps for the individual heat pumps.
Yes, it is a loop in the ground with 250' deep wells (U-tube type wells).
I don't see how 2 pumps in series reduces the head pressure on the piping. It just reduces the head requirement for each pump.
