MultiProtector: The Monitoring and Protection Unit

Pump protection module for positive displacement pumps enables damage prevention

The MultiProtector monitoring and protection unit offers you monitoring and analysis of pump data and warns you at an early stage of emerging damage to your positive displacement pump. The unit and the associated app (available for android and iOS)enable the definition of threshold values, documentation of the fault history and live diagnostics.

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. The lack of product ends the cooling and lubrication benefits. 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 these potential malfunctions early and are able to react accordingly. Data on product temperature, stator temperature, leakage, overpressure, motor voltage and motor temperature are continuously analyzed. If a threshold value is exceeded, a warning signal is triggered, and the pump is switched off. The app enables the definition of threshold values, documentation of the error history and live diagnostics. It offers you the simple display of the documentation in real time on all mobile devices, such as smartphone, tablet or laptop. With the evaluation and protection unit, you can both protect your pump from damage and optimize processes.
