Standard Features

ARMflo 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 E10 and E11 yield an overall efficiency that’s up to 41% better than wet rotor pumps of similar power.

The E Series also uses a compact motor that’s 30% smaller than other dry motor circulators. Designed for extended durability and very quiet operation, the E10 and E11 circulators include the new EnviroSeal mechanical seal, which can be field-repaired in under 5 minutes, as well as permanently lubricated stainless steel bearings.

While the durability of the Armstrong E Series rivals that of traditional 3 piece circulators, the E Series will cost about the same as wet rotors of comparable power.

• Ultra Quiet Design: No one wants to hear noisy pumps. Dynamic balancing of each ARMflo E Series circulator ensures quiet operation in residential and commercial installations.
• Compact Efficiency: Breakthrough motor and hydraulics technology deliver at least 41% higher efficiency than wet rotor pumps of similar power. As well, the E Series uses advanced motor technology, making it 30% more compact than conventional dry motor circulators.
• Smooth Operation Year-After-Year: Permanently lubricated ball bearings will provide trouble-free operation for years.
• High Head Application: ARMflo 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.
