High Tec pump
By MFParker (from Wayne, NJ) on 1/25/2014
I guess the days of the basic circulator pump are gone. I like bells and whistles and this pump has them all. Easy install. After that the fun starts. This pump has seven modes. Three based on watts, three based on gph and an auto adapt mode. On auto adapt it will alternately display power use in watts and gph being pumped through the system. It's fun to watch. Seems to run fine. I have three pumps/zones active and one inactive connected to a Taco 4 zone controller. I would recommend this pump based on based on the five months they have been in service.

All flanged circulator pumps have a flange outlet, which can accommodate piping sizes from 3/4" to 1-1/4" (1/2" and 1-1/2" on select models) when used together with pump flanges. For Grundfos cast iron circulators, these are:
