AquaMotion’s three-speed AM10 hydronic pump is a suggested replacement pump for circulators up to 26 gal. per min. The four-bolt flange for mounting in-line or 90° rotation capability make 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.
