Grundfos CUE

Overview applications

The CUE is a multi-purpose frequency converter suita-
ble for a variety of applications demanding reliable and
cost-efficient pump operation.
The CUE is used in five main fields of application:
Water supply and pressure boosting
Besides general water supply in municipal and indus-
trial waterworks, the CUE is used for these specific
applications:
• water supply
• pressure boosting
• washing.
The typical control modes are constant pressure, con-
stant flow rate. Stop functions are used to stop the
pump when low or no flow is detected.
Heating and air-conditioning
Liquid transfer in:
• heating applications
• cooling and air-conditioning applications.
The typical control modes are proportional pressure or
constant temperature.
Process and sanitary applications
Liquid transfer in:
• breweries and dairies
• pure-water applications
• process applications
• purification applications.
The CUE is typically controlled by an external control-
ler. The typical control mode is Open loop.
Groundwater
Typical applications:
• groundwater supply to waterworks
• irrigation in horticulture and agriculture
• dewatering.
The typical control modes are constant pressure, con-
stant flow rate or constant level control.
Wastewater
Transfer of:
• wastewater
• effluent
• drainage water
• process water.
The typical control mode is constant level function
(emptying function).
