My guess would be glycol loops for geothermal and heat transfer.

This is way too big for every residential use. I won't even say 'almost'. A typical home circulator is 1/25 HP. This is 3/4 HP. It pushes 3x the volume and its head is many many feet longer. If you have a boiler that's literally in a different building across your property...maybe...just to get the hot water across hundreds of feet of yard.
