3GK

The 3GK series is a high-efficiency synchronous circulator with a permanent magnet motor designed for heating and cooling systems.  

3GK circulators offer a variety of solutions in terms of performance, connectivity and communication protocol including the latest LIN one. 

Thanks to their extremely compact design they are the best choice for designers of heat pump systems. 

Main Features and Benefits 

• Compact design to be integrated in heat pumps appliances 
• Performances up to 9m head 
• External controlled via LIN or PWM signal. 
• Providing several information to the appliance (e.g. flow rate estimation, pump head estimation. This allows for greater system efficiency, the possibility of preventive maintenance, and helps to understand anomalies in the system or supply network, during installation and normal operation. 
• Meet requirement for explosive atmosphere (§22.116 and §22.117 of IEC 60335-2-40:2022) 
• Ceramic shaft, bronze barrier and high torque to cope with the worst fluid conditions.
