Armstrong Compass 20-20 Stainless Steel 180203-607

Armstrong Fluid Technology 180203-607 (180203-687) Compass H SS Variable Speed Circulating Pump - Ships anywhere in the US mainland for just $8!

Optimize domestic open loops and hydronic circulation with the premium, corrosion-resistant Armstrong Fluid Technology 180203-687 Compass H SS Circulating Pump. This high-efficiency, wet-rotor circulator is specifically engineered with a heavy-duty stainless steel body, making it ideal for potable water systems, radiant heating, and commercial or residential HVAC loops where cast iron pumps risk rust contamination.

Powered by an energy-conscious 115V motor pulling between 5W and 45W, the Armstrong 180203-687 integrates advanced Design Envelope technology for sensorless, demand-based control. It automatically adjusts its variable-speed output to match changing zone demands, delivering up to 20 GPM of flow and 20 feet of head pressure while slashing electrical usage by up to 70% compared to standard circulators.
