Armstrong’s Astro 2 three-speed circulators provide unmatched performance over a wide range of head and flow requirements, allowing contractors to adjust output in the field. This operating flexibility and range of pumping performance means just 16 models of Astro 2 circulators can be used to replace more than 160 competing circulator models. The bronze and stainless-steel circulators are in compliance with lead-free regulations, including California Health and Safety Code section 116875. The removable check valve allows contractors to reduce installed costs by eliminating multiple system check valves.
