Product Details

Basic pump controller for wastewater pumping stations
Designed for installations with one or two pumps, the Grundfos LC 231 and LC 241 level controllers are ideal for emptying and filling related to small wastewater transport, commercial buildings and tank-filling applications.

The controller is equipped with predefined settings to fit these applications for
an easier and quicker start-up in the specific application. The controller can
support up to five control levels for both analogue level transmitter and float
switch operation.

Start and stop signals are used for normal operation, and the optional dry-run signal will protect the pumps from dry running. The controller can run in two modes:

EMPTYING or FILLING.
For emptying applications, one or two pumps will run depending on inflow rate.
For filling applications, the opposite applies; if the tank is close to empty, one or two pumps will run.
Full control via your smart device
The LC controller is fully controlled via your smart device. It utilizes integrated Bluetooth communication that connects to the intuitive Grundfos GO Remote app, ensuring smarter and more optimal operation.

This enables you to easily exchange information between the controller and your smart device. From the moment the controller is installed and connected, the setup wizard and all pump operations are available in the GO Remote app (iOS and Android).

One- and two-pump systems
Wastewater transport – Pressurised pumping stations, Network pumping stations, Road drainage
