what is the difference between a UP26-99F and a UP26 -96F. I have a 96F and I am thinking of replacing it after about 15 years in service. Is there a "life expectancy for these pumps?
Read 1 answer
99F is a model with higher head (32 vs 24 ft of head). If 96F model has worked well for you, then there's no reason to replace it. 15 years is a great run and means both the system and the pump were (are) properly installed and maintained. If the circulator is working properly, there's probably no immediate need for a replacement, but it may be a good idea to have a spare. There's no "official life expectancy" we know of - only the standard warranty which comes with the pump, but when properly installed, they should last far beyond their original warranty.

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.
