Typical applications are pits with one (LC) or two (LCD) pumps in commercial buildings, private homes and municipal wastewater mains.
All LC/LCD controllers feature a control panel with switch and protection gear. They are designed especially for Grundfos pump systems, ensuring a perfect match.
Three series – six versions
The Grundfos LC/LCD range of level controllers comprises three series with a total of six versions:
- The LC/LCD 107 level controllers, operated by level bells
- The LC/LCD 108 level controllers, operated by float switches
- The LC/LCD 110 level controllers, operated by electrodes.
All are excellent for use with direct on-line start motors up to 11 KW. The LC/LCD range can also be supplied with an integrated star-delta starter for applications requiring larger motors, up to 30 KW.
A comprehensive range of accessories is available for the LC/LCD series, including an SMS modem option. In an alarm situation, the SMS modem sends a text message to your mobile phone. Operating data for each pump, such as running hours and starts, can be retrieved to your mobile phone by sending an SMS to the controller.
Grundfos Level Controls (LC/LCD) is designed for transfer of wastewater away from a wastewater pit.
It can be used for network pumping stations and mains pumping stations equipped with one to two pumps.
It can also be used for commercial buildings and municipal systems.

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.
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.
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.
The purpose of CAPS is to provide a complete tool that contains both an extensive catalogue of Grundfos products and a sizing program to select the most suitable pump for your application.
There is also a comprehensive pump replacement selection function for central heating circulator pumps, hot water pumps and wastewater S pumps, and a function for producing professional quotations that include curves, drawings, quotation texts, wiring diagrams, etc.
Last but not least, the software contains the instruction and operating manuals for nearly all Grundfos pumps in multiple languages. Service drawings, exploded views and parts lists are available for all sewage products as well as several other pump types.
CAPS is available in two versions: WinCAPS, available on CD-ROM, and the online version WebCAPS, available at the Grundfos website. Additional features available in WebCAPS include CAD Drawings and Literature.
