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 positive displacement pumps. The unit and the associated app 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. 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. 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 protect your pump from damage and optimise processes in the future. This will be available to you from May 25th, 2021.

MultiProtector, the Evaluation and Protection Unit

1 Temperature and voltage sensor
The temperature sensor measures the motor temperature and voltage to detect overheating of the motor at an early stage.

2 Temperature sensor
This sensor monitors the temperature of the pumped material to prevent temperature-related damage to the pumped medium.

3 Leakage sensor
The leakage sensor reliably detects conductive liquids and is therefore ideal for monitoring leakage and material moisture.

4 Temperature sensor
This sensor measures the temperature of the stator so that overheating and thus increased wear can be detected at an early stage.

5 Pressure sensor
Measures the hydraulic pressure at the pump's discharge connection and thus reliably protects against overpressure. 

  • Adjust and evaluate several sensors with one device
  • Simple installation, as only one device is required for all sensors
  • Simple commissioning through setup via app
  • Increased operational safety through advance warning and shutdown in the event of a fault
  • Prolongation of service life through information on preventive maintenance
  • Simple parameterisation, diagnosis and reporting in the MultiProtector app
  • Simple analysis of diagnostic data
  • Optimum condition monitoring via smartphone, tablet or PC
