		Armstrong Astro 2 hot water recirculation systems automatically circulate water through domestic hot water distribution pipes. This helps to ensure that everyone in the household has "instant" hot water at the tap when they need it, while also helping to conserve water and save water heating energy costs. Aquastat equipped models help save even more energy.
		Armstrong ARMflo E Series high efficiency circulators are perfect for heating or cooling applications such as Hot Water, Geothermal, Radiant Panel and Snow Melting in Large Residential and Light Commercial installations. The advanced motor technology and efficient hydraulic design of the E Series E10 and E11 yield an overall efficiency that’s up to 41% better than competitive pumps of similar power.
		Armstrong S Series circulators feature the unique Armstrong shaft and bearing module for ease of serviceability and maximum interchangeability. Oversized shafts of alloy steel machined to exact tolerances. Impellers are constructed from non-ferrous material and are designed for optimal water delivery. Available in bronze-fitted and in all-bronze construction.
