What is the difference between a UPS 26-99FC and a UP-26-99FC
Read 1 answer
3 of 3 people found this answer helpful.
The difference between Grundfos UPS and Grundfos UP models is that "UPS" models are 3-speed while "UP" models are single speed. In other words, a "UPS" circulator has a low/med./high switch which allows it to function at (3) different outputs (or, as 3 different circulators). This function is useful when selecting a precise circulator pump is difficult or if the system may have a planned addition in the near future. Due to a low price difference, most of our customers prefer the UPS26-99FC model over the UP26-99FC.
