LC level 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.

General Details


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:


  • 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.
