Armstrong E7, 182202-643, Flanged Circulation Pump
Armstrong Flanged Circulation Pump E7 Series - 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 yield an overall efficiency that's up to 41% better than competitive 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 E Series 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 usually cost the same as, or less than, wet rotors of comparable power.
