This contribution studies the impact of the rotor-stator interaction in a single-stage
progressing cavity pump on the flow rate and pressure. Specifically, we investigate the effect …

This contribution presents a novel wear dependent virtual flow rate sensor for single stage
single lobe progressing cavity pumps. We study the wear-induced material loss of the pump …

We present a model-based approach for a non-invasive online wear detection for
progressing cavity pumps. The approach is based on a model of the rotor displacement. All …

We present a virtual sensor that estimates the flow rate in progressing cavity pumps. The
approach uses a model for the interaction of rotor and stator inside the pump, combined with …

The classical progressing cavity pump design features constant rotor and stator geometries.
Pump efficiency decreases over time due to mechanical wear of the pump components …

Condition monitoring of pumps enables reducing downtimes, improved maintenance, and
lowering energy consumption. While condition monitoring is established for popular pump …

The wear and failure of pin joints integrated in coupling rods of process equipment can lead
to unpredictable breakdown with severe consequences. We present a simple algorithm for a …
