GRUNDFOS CUE
Variable-speed control for standard Grundfos pumps, with guided commissioning, pump functions and a complete range of power and enclosure variants.
- 1 x 200-240 V
- 3 x 380-500 V
- 0.55-250 kW standard
From a setpoint to stable pump operation
CUE combines a frequency converter with pump-specific setup and control functions. Add the appropriate sensor and output filter for the motor, cable and duty.
- SetpointPressure, level, flow, temperature or curve
- CUECalculates the required motor frequency
- Pump motorRuns only at the speed the system needs
- FeedbackSensor value closes the control loop
A drive that understands the application
Pump control modes
Constant pressure, proportional pressure, level, flow, temperature and constant-curve operation.
Integrated protection
Motor and process monitoring includes overload, underload, dry running and operating-limit supervision where configured.
System communication
GENIbus plus optional communication interfaces support supervision and integration into external control systems.
Flexible I/O
Analogue and digital inputs, analogue output and programmable relays connect sensors, setpoints and external commands.
Motor output filters
dU/dt or sine-wave filters are selected according to motor type, supply voltage and motor-cable length.

CUE is not a solar-input drive. It is supplied from the stated AC mains range. For direct solar pumping, use an architecture specifically designed for PV input, such as Grundfos RSI where applicable.
One platform across borehole, boosting and process pumps
SP and SPE borehole systems
Speed control for water supply and irrigation. SPE requires a compatible CUE architecture for its permanent-magnet motor.
