New for 2017, the 0015e3 three-setting, ECM-powered circulator replaces all three-speed hydronic circulators in its class. Its variable speed, high-efficiency ECM motor also uses as much as 85 percent less electricity. Useful for hydronic systems zoned with circulators or zone valves, and provides three maximum-feet-of-head pressure settings to match system requirements: Low (5 feet); medium (10 feet); or high (18 feet); with a maximum flow of 16 gpm. Features BIO Barrier that protects the pump from system contaminants, especially black iron oxide that otherwise tends to collect around strong ECM magnets. SureStart automatically unblocks a locked rotor and purges air from the circulator. The 0015e3 is double insulated; no ground wire needed. An integral flow check is included, and both two-bolt or two-way flange models are available. Qualifies for most state, regional, and utility efficiency incentive programs. Taco Comfort Solutions.
