Monitoring & Measuring

Tools to help you to get maximum performance out of your pumps.

HMD Kontro sealless magnetic drive pumps feature a range of monitoring and measuring tools. The diagram below shows all the options available, however, not all these would be used together, and some of these are not available for specific pump models. Please contact us for full details concerning your specific requirements.


Monitoring Device Locations

Monitoring Device Locations


  1. Drive Motor Monitoring – PCM (Power Control Monitors): Power Monitoring represents one of the best ways to protect your pump from system upset damage and avoid costly shutdowns, unexpected repair costs, and premature equipment failure.  A Power Control Monitor (PCM) is a simple electronic device that is easily installed in the electric motor control circuit of any given pump or other rotating equipment.
  2. Pressure Containment Shell Surface Temperature Detection:  These RTD (PT 100) or thermocouple sensors are permanently mounted to the containment shell and provide real-time monitoring of the temperature inside the magnetic coupling. 
  3. Flow & Liquid Detection:  These liquid or flow sensors are mounted at the suction or discharge connection and are designed to prevent pump start-up should the pump not be primed. If the system is allowed to run dry, these detection devices will stop the pump and prevent damage to its components.
  4. Pressure Monitoring:  This differential pressure switch is piped across the suction and discharge connections, serving to help monitor system pressure.
  5. Automatic Recirculation Control:  An automatic recirculation valve is associated with the pump discharge connection, as a means to provide a permanent bypass in the event of system flow fluctuations or a closed discharge valve. However, the automatic recirculation control will not protect against dry running.
  6. Liquid Sensing Probe:  This instrument is usually installed in conjunction with a secondary control. It provides early warning of containment shell failure before dangerous quantities of spillage can fill the coupling housing.
  7. Secondary Control: On some processes the added benefit of secondary control is regarded as essential. Sundyne HMD Kontro is able to provide pumps with secondary control devices to severely restrict any leakage into the immediate locality. Mechanical devices are fi tted to the drive shaft assembly that are activated in the unlikely event of containment shroud/shell failure, together with this the pump coupling housing is fi tted with gaskets to eliminate any leakage across the joining faces.
  8. Vapour Detector (VapourView):  Liquids and / or systems can produce vapour, especially in the event of a malfunction. To prevent this from causing a major problem, HMD Kontro pumps can incorporate a vapour detector mounted in the back of the containment shell, which will shut the pump down until the problem can be overcome.
