Benchmarking of Progressive Cavity Pump Technology

Minimized flow rates volume flows and extended limits of static mixing

In the dosing technology the performance level of dosing processes is still associated exclusively with basic pump technologies. It often stays out of mind that there are major differences in the performance of low-level components to high-quality premium products within a pump technology from manufacturer to manufacturer.

This aspect also applies to the application of the progressive cavity pump technology. The performance data of dosing precision, minimal volume flow rates - both in 1-component applications as well as 2-component mixing systems or maximum viscosity spreads in static mixing systems are largely determined by the achievable quality of the dispensing systems of manufacturers among themselves. ViscoTec Pumpen u. Dosiertechnik GmbH as an experienced premium supplier of the eccentric screw pump technology permanently works on opportunities for continuous performance improvement in dosing processes. Dispenser geometries and core components are developed and manufactured exclusively in house. An important role is given to the sophisticated, proprietary rotor and stator production environment: The achievable, unique manufacturing quality of ViscoTec directly affects the dosing precision within the offered product range.

Generally available performance specifications and comparative data on progressive cavity pumps are quite limited for overall comparison. ViscoTec dosing products are already used successfully for:

  • minimum dosing volumes as low as 0.001 ml (1-component systems) or 0.002 ml (2-component systems)
  • smallest volume flow rate down to 0.004 ml/sec. (1-component systems) or 0.008 ml/sec. (2-component systems)
  • mixing ratios up to 100:1
  • viscosity spreads up to 10⁶:1

With a focus on reliable process solutions ViscoTec is a specialized supplier of dosing solutions and knows how to handle highly reproducible dosing processes in the fully automated industrial production. Users can draw back to well-engineered solutions also for the most complicated tasks. They receive all necessary components from one source. Dosing processes can be planned optimally by ViscoTec and synchronized to the particular case of application – for highest process stability and best cost control.
