Armstrong 182212-665 E21.2 Cast Iron Circulator Pump

182212-665 Armstrong E21.2 Cast Iron Circulator Pump. Armstrong E Series high efficiency circulators are perfect for heating or cooling applications such as Hot Water, Geothermal, Radiant Panel and Snow Melting in Large Residential and Light Commercial installations. The advanced motor technology and efficient hydraulic design of the E Series yield an overall efficiency that’s up to 41% better than competitive pumps of similar power.

Armstrong E.2 Series circulators are permanently lubricated, so theres no requirement for maintenance during normal operation. When the mechanical seal wears out, it can be replaced in less than five minutes, which reduces on- site labor costs for contractors. The highly efficient dry motor design and hydraulics make the E.2 Series circulator more efficient than other fixed speed pumps in its class.

This excellent wire-to-water efficiency leads to energy savings that building owners will appreciate. The compact size of E.2 Series circulators makes them easy to install, even in confined spaces. The minimized angle-to- angle dimensions, combined with the Armstrong ordering of cross-referenced Spool Pieces, make it easy for contractors to upgrade an existing circulator with an E.2 Series circulator, without making changes to the installed piping.
