Geo-Flo manufactured a variety of pressurized and non-pressurized flow centers using an ECM variable speed pump from Grundfos called the Magna GEO 32-140 starting in 2012. Grundfos discontinued production of Magna GEO 32-140 in 2019. We purchased a large quantity of these pumps to cover anticipated Magna GEO flow center warranties, but the supply has been depleted. The UPMXL pump will not fit the Magna GEO or UP(S)26 series pump housing/volute, so you cannot simply remove and replace the motor. Further, since the life of a flow center is typically much longer than the warranty period, we developed two kits to allow customers to update their existing flow center with the variable speed UPMXL 25-124 ECM pump to prevent a total flow center replacement. These kits allow a repair to be made without flushing the ground loop with a flush cart. The FLP1L-FLK is designed for pressurized flow centers while the FLP1L-FLE is used for non-pressurized flow centers. Review the installation manual for detailed information on which flow centers are affected, and how these kits are installed.
