The Armstrong Astro 230 circulator pump brings adaptability to a new level. Designed to minimize the amount of inventory contractors have to transport to job sites, these three-speed units deliver unmatched performance over a wide range of head and flow requirements and can be adjusted over time to accommodate circulation zone fluctuations. The Astro 230 features an integral check valve to prevent backflow, eliminating the need for discrete check valve installation, and is available with union, sweat or rotated flange connections for easy installation in tight corners. Once installed, a built-in vent plug makes it easy to purge air from the system. No mechanical seals to leak. No couplers to break. No lubrication necessary. Versatility, easy installation and maintenance, and reliable Armstrong design make this our top circulator pump pick.
