Overview

For pumps, the most common reason for failure is dry running, which damages the mechanical seals and bearings. The Grundfos LiqTec™ is an electronic pump protection unit that prevents the pump from dry running and reduces the rate of failure.

The LiqTec™ can be used for protection against high liquid and motor temperature. The sensor prevents excessive liquid temperatures above 266 °F from damaging the pump. In addition, the LiqTec™ can also be connected to the motor’s thermistor or PTC. If motor temperature exceeds a certain level, the sensor will stop the pump immediately.

The LiqTec™ is designed to be used with CR, CM and MTR pumps in water applications.
