MultiProtector: The Monitoring and Protection Unit

Two of the biggest dangers for displacement pumps are dry running and overpressure. Dry running damages the elastomer of the progressing cavity pump by overheating within a short time. Due to the lack of medium, there is no cooling and lubrication. In addition, positive displacement pumps can briefly deliver more than twice the pressure, which leads to a sudden load on the joints, the drive chain and the gear motor. With the MultiProtector, you can detect possible malfunctions at an early stage and react accordingly. Data on medium temperature, stator temperature, leakage, overpressure, motor voltage and motor temperature are continuously analysed. If a threshold value is exceeded, a warning signal is triggered, or the pump is switched off.
