CUE

Overview

Overview

The CUE series are frequency converters for the speed control of a wide range of Grundfos pumps.

The Grundfos CUE is the latest addition to our E-solution range of speed-controlled pump systems designed for a series of applications such as industry, building services, municipal or private water supply, wastewater and irrigation. This new series of wall-mounted frequency converters with features and functions for Grundfos pumps and a special user interface offers features similar to those of the Grundfos E-pumps, which are fitted with motors with an integrated frequency converter.

With a CUE solution you can control the speed of virtually any Grundfos pump, irrespective of size, power range, and application area.

Applications

The CUE is a frequency converter for Grundfos pumps, providing a series of predefined functions which make the converters easy to use in almost all application areas. A series of predefined control modes, such as constant pressure, proportional pressure, constant level or constant flow, makes it very easy to set up a system in only a few steps. A special start-up guide will lead you through the set-up of the CUE.

Information and advice

Grundfos is a world-wide provider of pumps and related systems. We have a trained staff of service engineers who will be able to support you during the installation phase of the pump or solution. Grundfos products are manufactured to very high standards, which helps to ensure a long life. Our many years of experience of different kinds of installation and with installation techniques are also key factors for maximising the lives of your Grundfos products or systems.

We will be able to support you with the following:

  • Information about the proper protection of our pumps
  • Advice on the physical positioning of the pump for necessary service/repair
  • Advice on the physical positioning of the pump to maintain proper operation
  • Correct cabling to fulfil the requirements of good practice and electromagnetic compatibility.

Please contact your local Grundfos company to obtain full support for your new installation.

Commissioning

In order to achieve optimum performance, it is very important that the product/system is set up and adjusted correctly from the outset. The knowledge and experience of the Grundfos service technician, and the use of dedicated Grundfos service tools to adjust the performance of the pump, together guarantee that the greatest possible efficiency and fully correct operation of the equipment are both achieved. Commissioning of the pump is recommended in the following cases:

  • If the pumps are controlled by a frequency converter
  • If the pump system is operating in a large system, e.g. a building management system
  • If the user wants to be trained in the proper operation of the pump
  • If the pump is a vital link in an important production/application facility
  • Where the setup is crucial for the Grundfos product to operate for its full planned life, e.g. in water treatment applications. In such cases commissioning is not only recommended but required
  • Where safety is an issue, e.g. in disinfection systems
    The commissioning is performed in a step-by-step procedure, and a report of the settings of the pump is produced.

Please contact your local Grundfos company to arrange for the commissioning of your newly-installed Grundfos product.

Optimisation

Grundfos offers an efficiency analysis of your existing pump system, providing you with suggestions for increasing efficiency and thus for achieving cost savings over time.

Increase the efficiency of your existing system

Conducting an efficiency analysis of your existing pump system provides you with a basis for increasing efficiency and thus for achieving cost savings over time. An efficiency analysis results in suggestions for increasing efficiency and will show how this will save you money.

Grundfos offers the following levels of analysis for assessing the efficiency of your pump system:

  • Installed base checks.

 

A basic evaluation is carried out purely on the basis of the data from the identification plate on the pump, comparing its performance with that offered by newer, more efficient technology and materials found in modern pumps.

  • Pump efficiency quick check.

 

Pressure and the consumption of the pump in kWh are measured. Flow is estimated on the basis of available pump data and the results of the measurements.

Some of the resulting suggestions for improving efficiency might include a speed control upgrade, a motor upgrade, differently dimensioned pipes, the installation of a controller, or perhaps an agreement for routine service.

Complete Pump Audit

The efficiency analysis offered by Grundfos makes up the first step in our Pump Audit, a diagnostics tool that we use to check whether the pump system is operating at the optimal energy consumption to guarantee that your costs are kept to an absolute minimum – now and in the future. See "Replacement analysis" to find out more about the Grundfos Pump Audit.

Service agreement

A Grundfos service agreement ensures the efficient and uninterrupted operation of your pump system and gives you access to Grundfos service centres and authorised service partners worldwide, 24 hours a day.

Prevention is better, and more cost-effective, than cure

Once you have purchased your pump, you will want it to function efficiently and reliably; a formal service agreement with Grundfos will give you peace of mind. It also makes sound economic sense, giving you a firm costing for your maintenance budget and access to substantial discounts.

You simply combine a range of service programmes to suit your needs – and then let us carry out scheduled maintenance visits to prevent downtime. We offer three types of service agreement, available for all pumps:

  • Basic
  • Extended
  • Total.


Whichever agreement you choose, your equipment will always be serviced by specially trained staff.

The cost-effective choice

Well-maintained pumps can reduce your energy consumption by up to 50 %. Furthermore, it's worth remembering that in a series of pumps working together, one faulty pump can affect all the others. A Grundfos service agreement keeps the total cost of operating a pump to a minimum. Our careful calculation of the life-cycle cost of all our products means that we have an overview of the true costs of owning each of our pumps.

Signing up for a service agreement and letting our highly-skilled service technicians service your pumps is a safeguard against unforeseen expenditure. Regular servicing and maintenance of your pumps will ensure that they operate with optimum efficiency.

Repair and maintenance

Grundfos Service can advise you on efficiency issues, offering suggestions for saving money in the long term.

Not all our products need spare parts. Our pumps are designed to provide low energy consumption and the highest possible performance throughout their lives. For some pumps, the greatest efficiency and reliability are achieved by replacing worn-out pumps rather than repairing them.

Naturally, you can always call Grundfos for repair and maintenance of pumps you have purchased from us. It is important to remember that an upgrade or even a replacement pump can be cheaper than repair in the long term.

Effective service – wherever you are

Grundfos Service is always close by. Working in collaboration with our local authorised service partners we offer worldwide service. Help from qualified pump professionals is never far away, whether you need immediate assistance or are interested in hearing about opportunities for making savings.

Grundfos Remote Management

Grundfos Remote Management is a cost-effective, secure and reliable way to monitor and manage pump installations from an Internet PC at a very low cost.

Connecting pumps and people

With a secure and reliable remote management system, you can monitor and manage your pump systems from an Internet PC at a very low cost.

Grundfos Remote Management is a cost-effective and straightforward system for monitoring and managing pump installations in commercial buildings and in water supply and wastewater systems. It reduces the need for onsite inspections, and in the event of an alarm or warning, the relevant people are notified directly.

The system offers a wider range of benefits and functions than mobile-phone-based monitoring. For those who do not require remote process automation, Grundfos Remote Management is the ideal solution for monitoring and remote control, rather than traditional SCADA (Supervisory Control and Data Acquisition) systems. Initial investment is minimal, and a fixed low fee covers data traffic, hosting costs and system support, including back-up of all data.

Efficient alarm management

The on-call schedule in this new telemetry system ensures that alarm messages from onsite controllers go directly to the relevant people. The system manager can log on from a PC anywhere and plan who is to receive alarm messages from each installation at any given time of the day. Managers can plan for years ahead, and can easily handle day-to-day exceptions to the schedule.

Optimise service and maintenance

Changes in pump performance can be tracked using trend graphs generated automatically by the system. This tracking can give an indication of any wear or damage in the installation, and service and maintenance can be planned accordingly.

The communication interface (the CIU271 modem) enables data transmission via GPRS/SMS from your Grundfos pumps and controllers. The built-in multi-purpose I/O board allows you to connect sensors and switches.
