Domestic circulator has novel features

The Lowara Ecocirc high-efficiency domestic circulator from Xylem can reduce electricity costs by up to 90% compared to traditional fixed 3-speed pumps, providing a payback to two to three years. These pumps have an electronically commutated spherical motor with only one moving component — the impeller/rotor unit, avoiding the problem of shaft seizure if the pump has not been used for some time.

The spherical-motor design does not have a shaft and requires only a single self-realigning bearing, which minimises operating noise and reduces the need for costly precision components.

The flow of water through Ecocirc is kept away from permanent-magnet parts, so the pump is not susceptible to blockages from magnetite or sludge.

Integrated over-temperature protection reduces the speed of the pump or brings it to a complete stop. The system will then try to restart the pump once a minute to ensure it never overheats.
