In 2018, Grundfos announced that they would cease production of the Magna GEO variable speed
pump. In response, Geo-Flo developed a new line of variable speed flow centers to replace the
Magna GEO flow centers. In addition, we secured a large quantity of Magna GEO pumps for warranty replacements for the flow centers we have manufactured.
The new line of variable speed flow centers will feature the Grundfos UPMXL 25-124, 208-230V,
50/60 Hz single-phase variable speed pumps, and will be available in pressurized and non-pressurized with both standard and inverted PWM profiles. These new products cover all previous versions
of the Magna GEO and will start shipping in the upcoming weeks.
The UPMXL pump is a powerful, efficient pump with a small footprint. The motor uses just 180
Watts maximum versus 195 for the UPS26-99 and 230 Watts for the Magna GEO. Despite this lower
energy use, the UPMXL provides better performance than a UPS26-99 and nearly the same as the
Magna GEO. In fact, a single UPMXL can replace two UPS26-99s in some applications. See technical
details for more information. Like the Magna GEO, the UPMXL is a permanent-magnet, ECM pump
that includes condensate drain holes, double-coated wiring, and spacing between the electronics
and motor allowing operation in condensing environments. The pump is driven by an external lowvoltage PWM signal that controls the pump depending on the system requirements. Since the pump
housing/volute is designed for optimum efficiency, the pump motor will not bolt on a UP/UPS or
Magna GEO volute.
