Armstrong 20 BU-T Astro Express System, Circulator Pump ...

Armstrong 20 BU-T Astro Express System, Circulator Pump (Timer, Line Cord & Valve) (110123-400) The Astro 20 BU-T circulator is a small pump with twice the capacity of other circulators. It can handle more flow to more destinations (up to 5 valves) for the kind of "branch plumbing" that can make hot water distribution in a large or ranch-style home such a challenge. Most dedicated return systems are oversized and have a short duty cycle when the aquastat is activated. Our injection system uses lower flow to maintain a more stable water temperature at the hot water faucet and prevent noise and erosion. Plus, larger openings ensure easier flow, so several people can turn on taps throughout the house and they will all get hot water instantly.
