FEATURES

Armstrong Astro 290SS 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.
