Grundfos Blueflux®


Correct drive configuration

Grundfos Blueflux® VFDs are configured to suit the task at hand exactly. This is essential in order to minimise the pump motor's electricity consumption. The VFDs have a range of special features that maintain system control over multiple parameters, such as maintaining:

  • Constant pressure
  • Constant differential pressure
  • Proportional pressure
  • Constant level
  • Constant temperature

Grundfos Blueflux® VFDs come either as external units with unique software for 33 Grundfos pump ranges or as integrated and fully pre-programmed systems, delivered as plug'n'pump solutions.

Without precisely the right motor, even the best pump will consistently waste energy. That's why we have developed our own Grundfos high efficiency motor technology specifically for pumps. We call it Grundfos Blueflux®.

Grundfos Blueflux® solutions include high efficiency motors and variable frequency drives (MG motors, MGE motors and CUE drives). These winning combinations will at least meet and often exceed legislative requirements such as the EuP IE3 grade.

Integrated for top performance

Blueflux® motors and VFD's are designed to integrate perfectly with each other and both are designed exclusively for pumps. As well as increased efficiency, this also ensures greater reliability and a fine degree of operational control. The VFD's are programmed with Grundfos software and can come preset and pre-attached to the motors or be purchased separately.

Every aspect of the Grundfos Blueflux® motor has been optimised to minimise energy loss and contribute to outstanding performance and reliability.

Benefits of Grundfos Blueflux®:

Lower life cycle costs?

Energy generally accounts for 85% of a pump's overall life cycle costs. So by cutting down that energy consumption Grundfos Blueflux® high efficiency motor technology can reduce life cycle costs by up to 50%.

Lower running expenses?

The outstanding reliability of Grundfos Blueflux® reduces day-to-day service costs. Every Grundfos Blueflux® solution is built to cope with the demanding operating conditions of many professional sectors.

Superior system control

Grundfos Blueflux® variable frequency drives (VFDs) are perfectly matched to the pump they are attached to. When used in combination with a sensor they enable a very fine and consistent level of control over chosen parameters.

Longer operational lifetime?

All the components are of Grundfos quality and each motor and VFD is designed to operate for years and with minimised wear and tear in mind.

Lower environmental impact?

Grundfos Blueflux® not only reduces emissions through operational efficiency, Grundfos also makes the manufacturing process itself as efficient as possible and uses components with a very high degree of recyclability.
