Control and monitoring unit
The Grundfos LiqTec is a unique monitoring unit that prevents dry-running damage. It works by sending a heat pulse through the sensor to measure its exact temperature. During normal operation, the sensor is cooled by the liquid in exactly the same way as the shaft seal and other internal pump parts, and no action is necessary.

If, however, there is no liquid in the pump, the LiqTec detects a high temperature in the sensor and immediately shuts down the pump before any damage is done. This further reduces the risk of your Grundfos pump breaking down by up to 50%.
