The 27 poles stator not only gives an equal propulsion, due to the True Sine Wave technique it also has an unmatched torque.
The power module uses True Sine Wave technology for high reliability. Unlike brushless DC motors with square wave technique, BLUE ECO pumps use True Sine Wave technology for the best features: high efficiency (90%), noise free running, high torque, wide RPM range, CO2 reduction.
The way BLUE ECO pumps are constructed prevents any internal leakage. The rotor rotates in the same water that lubricates the bearings. With a unique rinse-system, different for both models, the water inside will be continuously changed during operation.
The controller is developed by Estrad BV and produced under supervision of the University of Shenzen, China. This leading university is working close together with Europe’s biggest companies and universities in this area.
The University of Shenzen supplies the software for the controllers and every controller is individually checked and certified. Every pump also undergoes an extensive test procedure and comes with its own unique test certificate.
The Blue Eco pump is the only pump in its class that has both the European CE certifications as well as the German “TÜV Prüfungs and Test Certificate”. This guarantees extra quality and safety.
