Armstrong E2 Series High Efficiency Circulator Pump

For heating or cooling systems, such as hot water, geothermal, radiant panel and snow melting in large residential and light commercial installations the Armstrong E.2 circulators draw on advanced motor technology and efficient hydraulic design to achieve excellent wire-to-water duty point efficiencies. E.2 Series circulators have been re-designed to improve durability and provide enhanced protection against leakage and water damage to electrical components.

Features:

• larger, stainless steel shaft
• new sealed, permanently lubricated bearings
• bellows-style mechanical seal with silicon carbide wear surfaces
• new water slinger to protect motor against water intrusion

These design improvements, supported by extensive factory testing, make the E.2 Series circulator a reliable, troublefree pumping solution that’s perfect for residential and commercial installations.  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 five minutes, which reduces onsite labor costs for contractors.
