Higher Efficiency & Improved Performance

Effortless “SMART” Heating Circulator

Through microprocessor technology the fields of the motor are provided the precise frequency and voltage for optimum performance. A permanent magnet motor eliminates the requirement for input power to magnetize the rotor, thus maximizing efficiency. This unique design offers superior starting torque when compared with standard induction motor type circulators.

Simplicity – The only moving part is the rotor/impeller unit. The shaft, shaft seals and conventional bearing bushings have been eliminated.

Control Modes

auto: The ecocirc® auto has a proportional pressure control, which automatically adjusts the pump performance continuously and automatically to the requirements of the heating system. When the zone or thermostatic valve closes, the pump performance is reduced to save energy and to avoid velocity noise in the system.

vario: The ecocirc® vario allows for step-less speed control to set the pump performance to meet individual system requirements.


The ecocirc® auto and vario circulators were designed with highly efficient electronically commutated permanent magnet motor (ECM/PM technology) specifically for hydronic systems.
