AquaMotion’s three-speed AM10 hydronic pumps are designed to extend the range of offerings as a suggested replacement pump for circulators up to 26 gpm. The four-bolt flange for mounting in-line or 90° rotation capability makes it suited to become a replacement service pump. The amp draw is 0.45 on low speed, 0.60 on medium speed and 0.75 on high speed. The cartridge can be removed and cleaned and inserted back into the pump. Both the cast-iron and stainless-steel units use the same cartridge, thus reducing inventory for wholesalers or contractors.
