Description for AM3-ST1

The AM3 is designed for circulating hot or chilled fresh water in open or closed loop low flow applications. Ideally suited for Domestic Hot Water Recirculation Systems, Heat Recovery Units, Potable Water Systems and Water Source Heat Pumps.

The revolutionary Green ECO-Cartridge Design is the heart of the circulator and contains all moving parts. It has the only field replaceable and field serviceable cartridge on the market. In case of failure, competitive manufacturers have to replace their entire cartridge, motor assembly or pump, increasing the foot print on the environment and doubling the cost to the consumer. With our pump, pull out the rotor assembly, flush the cartridge with water and reinstall it. Simple, cost effective, patented.
