Armstrong Astro 280SS Circulator Pump

This circulating pump, Astro 2 series, is designed for use in potable water systems.  This model features a stainless steel construction making it suitable for pumping domestic water.  The pump operates quietly and requires zero maintenance.  Since water conditions can vary with geographical location (i.e. amount and type of dissolved solids), it is recommended that the operating temperature of the fluid be kept as low as possible (i.e. below 150°F) to avoid precipitation of calcium.

*Flanges must be purchased separately.


  • Stainless steel body construction
  • Ceramic shaft and bearings
  • Cross-reference information is printed on the box, for convenient access
  • e-coating on the inside of cast-iron volutes provides enhanced corrosion protection for improved reliability
  • Flange-to-flange and bolt-to-bolt compatibility offers quick and easy exchange of competing models
