Recirculation Pumps~ Armstrong



Globaltowne sells Armstrong Recirc Pumps

Recirculation Pumps can be used to provide instant hot water at a faucet or from radiant floors using water or a glycol type liquid for floor warming.

Armstrong is a leader in pump technology and these pumps are made in New York and Canada in the Buffalo / Niagara area.

Used with a tankless heater, the recirculation pump circulates water from a small tank heater within a loop to each faucet. The pump can have a timer
and a temperature sensor so the loop stays warm but the mini tank water heater is not on all the time. When a faucet is turned on, the tankless heater sees the flow and turns on and the heated water flows through a check valve and to the open faucet.

Armstrong has an all in one system called the ASTRO EXPRESS. The Astro Express System works like a thermostat.The snap-acting valve opens and closes to circulate hot water so it stays at a specific temperature throughout the distribution system. Hot water at each tap stays hot, and cold water stays cold.
A timer automatically ensures that the water is recirculated regularly; and can be set for multiple activation periods per day. It can be set to circulate water only during normal usage hours (i.e. not in the middle of the night when everyone is asleep). The timer includes manual on/off overrides to normal automatic operation.
Each system comes with one valve, which is installed at the faucet furthest away from the water heater. This ensures that hot water is delivered to all the faucets in between. A home that has a distribution line with a number of branches, will need a valve for the faucet at the end of each branch. Additional valves are available separately


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.
