Ecocirc Series CONSTRUCTION CHARACTERISTICS Improved hydraulics to improved efficiency: The very latest computer simulations have further optimized the pump housing and the impeller. The cast iron pump housing is cataphoresis coated completely and is therefore resistant to corrosion. The spherical rotor. The permanent magnet rotor/impeller unit is the only moving part. Spherical motor pumps are shaftless, and therefore whisper quiet over the whole lifetime. In case of an indicated rotor blocking, emergency software shakes and vibrates the rotor to avoid further blocking. The revolutionary Anti-Block-Technology allows to separate the magnetic chamber from the flow, preventing magnetite and sludge to block and damage the pump. Blocking up, even in very old, open systems is impossible by our pump design. Easy to control, Two in one control: Step-less manually control with constant speed, displayed by a white LED, or alternatively automatic differential pressure, displayed by a blue LED. Optimized motor technology: Doubled electric windings combined with the latest Bit processor technology - that also makes the Ecocirc even more efficient. Overtemperature protection feature that slows down the circulator in case the temperature of the electronic module is too high and shuts it down when temperature rises above the safety limit. The circulator will automatically restart after having cooled down. Always easy to access: The screw ring design results in a pump motor that can be rotated in any position around the circle. The electrical connection as well as the control knob is therefore easy to access. metres length three cores cable (G.7) for connection to the single-phase power source. Automatic air purge: Quick automatic air-venting-mode for a safe operation. According to EN standards -, --, -, -, 97-, 97-. CONTROL MODES Automatic regulation: the pump automatically adjusts the working conditions based on the requirement of the system. When the pump detects a decrease in the flow, the inverter reduces the differential pressure of the pump until it reaches the required head. ACCESSORIES SORIES Pipe unions. Insulation shell. INSTALLA ALLATION Suitable for installation in vertical or horizontal piping, in this last case not with the motor housing upward.

The values given are guideline values which are bound to vary slightly according to the model, especially for gate valves and non-return valves, for which it is a good idea to check the values supplied by manufacturers.
