Real-time availability of all process data is the basis for the implementation of Industry 4.0. Intelligent field devices from Schmalz, such as the compact ejector X-Pump, gather this process data, store it and make it available in the network. Its diagnosis and predictive functions deduce information from this regarding the condition of the system (e.g. wear or contamination). They detect gradual changes as well as imminent malfunctions. This enables avoidance of unplanned machine downtime and an increase in system availability.
