Circulator: Armstrong Fluid Technology
Armstrong Fluid Technology has expanded its Astro wet-rotor circulator offering with the introduction of the Astro 2 Series. Featuring four new sizes, the company says its Astro 2 Series now offers flange-to-flange and bolt-to-bolt compatibility with 100% of competing models in terms of performance.
The new models are also designed to address a broader range of applications. Key features include: three field-selectable operating speeds, double the head and triple the flow, a plug-in terminal strip to save time on installation, e-coating on the inside of the cast iron volutes to provide enhanced corrosion protection, pre-installed high-flow check valve and availability in cast iron, stainless steel and lead-free bronze. In addition, Armstrong has announced a five-year warranty on both the Astro and Compass Circulators.
