the ecocirc is setting new standards!User-friendly, speed controlled heating circulator with energy efficient spherical motor technology.
Control Modes
auto: the ecocirc auto has a proportional pressure control which automatically adjusts the pump performance continuously to the requirements of the heating system. based on the curve that is set on the adjustable dial. 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.
Application the ecocirc
auto and vario circulators were designed
with highly efficient electronically commutated permanent magnet motor (eCM/PM technology) specifically for hydronic systems.
Dry Run Protection
the ecocirc is protected against dry run conditions. the circulator recognizes when there is no water in the pump housing and automatically enters a protection mode until the presence of water is detected.

Reliability • eFFiCieNCy • SiMPliCitySimplicity the only moving part is the rotor/impeller unit. the shaft, shaft seals and conventional bearing bushings have been eliminated. the rotor/impeller has anti-block technology.
the anti-block technology separates the main fl ow of the pumped media completely from the permanent magnetic parts. it is virtually impossible for the ecocirc auto or vario to block-up even in an old open system.
Higher Efficiency & Improved Performance through microprocessor technology the fi elds 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 effi ciency. this unique design offers superior starting torque when compared with standard induction motor type circulators.
The Perfect Balance of
Always easy to access. The screw ring design results in a pump motor that can be rotated in any position around the 360° circle. Therefore the electrical connection as well as the control dial is easy to access.
