Astro wet-rotor circulator line includes four additional sizes that offer flange-to-flange and bolt-to-bolt compatibility with competing models. Designed for trouble-free operation, the unit has three field-selectable operating speeds, a plug-in terminal strip to save time on installation and a preinstalled high flow check valve. The circulators have an e-coating on the inside of the cast iron volutes to provide enhanced corrosion protection.ArmstrongFluidTechnology_IN
