Frequency converters


A variable frequency drive is used to control the motor speed and torque of a pump by varying motor input frequency and voltage. This has proven to be the most efficient way of adjusting pump performance when a pump is exposed to variable flow requirements.

Grundfos CUE frequency converters ensure optimal adaptation to changing conditions. That gives you a perfect match between hydraulics, motors, electrics and all other mechanical components that make up a comprehensive pumping solution – and you are guaranteed the best possible efficiency point.
