With the addition of the new Astro 70F and BF, Armstrong now offers a high head, low-flow rate pump suitable for use in applications such as wood fired boilers, solar heating hydronic systems and even large residential domestic hot water recirculation systems with long return line pipe runs. All Astro series circulator models are available with common two-bolt mounting flanges. This mounting arrangement allows for easy circulator installation and subsequent removal and replacement. The Astro 20 and 25 models are also available with union and sweat connection designs.

Additional features of Astro series circulators include:

  • New screw-less terminal strip with lever-operated spring clamps that grip each conductor of the electrical cable. This provides ease of connection of the electrical connections inside the box.
  • Redesigned terminal box that is flush with the top of the motor, allowing ease of installation into tight spaces.
  • Available in bronze or cast iron versions.
  • Compatible with Armstrong's CIF series of circulator isolation flanges.
