Grundfos GeoLink Flow Center Pump

Got a GeoLink flow center here with dual Grundfos UP26-99 pumps. These came out of a geothermal setup. They've definitely seen some use and have some rust on the flanges as you can see in the pics, but these Grundfos pumps are usually pretty tank-like. Selling as-is, might be good for parts or if you need a backup for your HVAC system. Not sure on the exact working state right now so priced accordingly.
