The Armstrong E.2 circulators draw on advanced motor technology and efficient hydraulic design to achieve excellent wire-to-water duty point efficiencies.

• Lead-free
• E.2 series circulators have been re-designed to improve durability and provide enhanced protection against leakage and water damage to electrical components
• The compact size of E.2 series circulators makes them easy to install, even in confined spaces
• The minimized flange-to-flange dimensions, make it easy for contractors to upgrade an existing circulator with an E.2 series circulator, without making changes to the installed piping
• 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
• E.2 series circulators are permanently lubricated, so there's no requirement for maintenance during normal operation
• When the mechanical seal wears out, it can be replaced in less than 5 min, which reduces onsite labor costs for contractors
• Lasting components and refined product design for extended durability and low lifetime cost
• New water slinger to protect motor against water intrusion
• Bellows-style mechanical seal with silicon carbide wear surfaces
• Larger, stainless steel shaft
• Permanently lubricated stainless steel bearings
• Stainless steel face plate
• EPDM volute gasket
• Silicon carbide enviroseal cap with viton elastomer
• Open system
• (2) bolt flanges, 1-1/4 in Dia
• 3-years warranty
