Intelligent speed control. Maximum energy savings

The CUE 120 is a compact, general-purpose variable-speed drive designed to optimise pumping systems using horizontal/vertical- single-stage, multi-stage, and submersible pumps. Built with a durable design with 3C3 conformal coating for indoor installations (IP20), it supports motors up to 110 kW and operates seamlessly across the full Grundfos range of pumps and pumping solutions. Perfectly suited for pump applications in industrial pumping solutions, Grundfos CUE keeps pump speed optimal and reduces energy consumption.

Versatile across applications

The CUE 120 is ideally suited for a wide range of applications, including:

  • Industrial pumping solutions- Water treatment, transfer & distribution, heating, cooling, and other process applications
  • Wastewater networks
  • Building services

Seamless system integration

The drive enables easy integration with SCADA systems, featuring:

  • Modbus RTU RS485 (standard)
  • Profibus, Profinet, and Modbus TCP/IP (optional)

Energy efficiency and cost savings

By reducing pump speed by just 20% using VFDs and sensors, energy consumption can be reduced by up to 50%.

The CUE 120 offers a cost-effective way to:

  • Lower operating costs
  • Reduce carbon emissions
  • Improve the efficiency of existing pump systems

Key benefits beyond energy efficiency include:

  • Eliminate Water Hammer Risk
  • Maximize Equipment Lifespan
  • Achieve Precise Process Control
  • Enhance Operational Flexibility & Asset Protection
