Grundfos high-efficiency IE5 motors and pumps Grundfos’ E-pumps with integrated frequency converters are designed for total control, customer convenience and environmental sustainability. Grundfos’ MGE E-motors exceed the IE5 requirements by more than 2% with a motor efficiency of 95.7% at 380 V/2,600 rpm. The built-in application control in MGE E-Motors reduces energy consumption of the pump and optimizes the performance and efficiency of the entire system. The permanent magnet synchronous motors (PMSM) are designed for frequency converter operations and optimized for pump applications and high part-load efficiency. The PMSM also has a built-in frequency converter for variable-speed operation with benefits in pump
