Wall-mounted solutions for speed-controlled pumps

The Grundfos CUE is the newest addition to their line of speed-controlled pump systems for industry, building services, municipal water supply, municipal wastewater, and irrigation applications. The CUE offers E-pump functionality and user interface for pumps above 30 hp, as well as for power supplies outside their E-pump program.

VERSATILE RANGE & APPLICATIONS

  • Suitable for most centrifugal pump types and all application areas.
  • Compatible with new and existing Grundfos pumps and most ranges outside of E-pumps
  • Can be used where integrated solutions will not fit, is not wanted or is prohibited such as:
  • Submersible installations
  • Wastewater applications
  • Water supply and irrigation applications
  • Hazardous or explosive areas
  • Sanitary installations

EASY INSTALLATION

Simply designate a few application-specific settings and variables such as pump family, control functions, sensor type, and setpoint, and the CUE automatically sets necessary parameters such as ramp times, minimum speed, controller constants, and more. The optional Grundfos R100 Remote Control helps complete the task in just minutes.

  • Plug-and-pump installation and operation
  • Extensive control and monitoring possibilities
  • The same user-interface and functionality of the E-pumps, plus an advanced controller and a number of monitoring functions
  • Extensive possibilities for monitoring, frequency converter, and surroundings – as well as remote control and supervision via bus interface and input/outputs

EFFICIENCY & SUSTAINABILITY

Achieve energy savings of up to 50% while increasing comfort and convenience for both installers and end users!

Approximately 70% of the total costs incurred during the life of a variable-speed pump is attributed to power consumption. By controlling pump speed according to demand, the Grundfos CUE helps users reduce CO2 emissions and save energy.

COMPARE
E-solution versus fixed-speed solution in a typical pump application with variable pumping demand*:

  • Annual Energy Savings: Up to 50% (typically 25-35%)
  • Annual Reduction in CO2 Emissions: Typically 2,150 lbs. per 5 hp
  • Reduction in Life Cycle Costs: Typically 25%
  • Payback Time for the Extra Investment in an E-solution: 2 to 3 years

*Figures are based on a pump with a 5 hp motor in an application running 12 hours per day, 220 days per year. Average CO2 per kWh is set to 0.82 lb. Life cycle cost calculation is based on a 10-year period.

FEATURES AT-A-GLANCE

  • Plug-and-pump convenience with easy installation and commissioning.
  • Soft start and stop feature that eliminates water hammering.
  • Built-in PID controller offers constant pressure independent of the required flow.
  • More than 100 configuration possibilities, encompassing a power range from 0.75 hp to 300 hp.
  • Available with five different power supplies, two enclosure classes, and more than 24 different output powers.
  • Automatic detection and setting of correct rotation direction to ensure that the pump is running in the proper direction, eliminating the need for manual interchange of motor wires.
  • User-friendly operating panel with backlit graphical display and buttons
  • Menu settings structured identical to the R100 Remote Control operating panel used in conjunction with E-pumps.
  • User friendly functions for proportional pressure, stop function, dry-running protection, duty/standby, and motor bearings supervision.
