Pumps

January 11, 2011

ITT Bell & Gossett has won the prestigious 2011 AHR Expo Innovation Award in the inaugural Plumbing Category for its ecorcirc® hot water circulator.

A state-of-the-art design allows the ecocirc to use 68% less energy than most standard pumps and can save an average family of four more than 12,000 gal of water a year by eliminating the need to wait for the water to get hot. Using only 10 W of power, the equivalent of a small nightlight, the ecocirc can save a homeowner hundreds of dollars in energy costs a year.

Featuring the exclusive ECM (electronically commutated motor) technology and a patented spherical motor design, the ecocirc eliminates the need for a conventional shaft, seal and bearing assembly. The rotor/impeller is the only moving part in the circulator and it is magnetically balanced on a stationary ceramic bearing inside the pump housing to provide silent, long-lasting operation. Additional features include:
  • Maintenance free, long-lasting operation
  • Seal-less, leak-free
  • Resistant to scale build-up, ensuring optimal flow
  • Only self-realigning bearing in the small pump market
  • Self-lubricating and automatically cooled by pump media
  • Resin-encompassed stators eliminate corrosion
  • Energy savings pay back the cost of the pump within months
  • The magnetically centered rotor can tilt to avoid small particles
  • Built-in temperature sensor automatically adjusts frequency and voltage
  • Built-in 24-hour timer
  • Motor is separated from wetted parts by a stainless steel partition
  • Superior starting torque
  • Solar model available
  • Easy to install
