Strong outgassing, highly viscous, abrasive, shear sensitive or chemically aggressive? Fluids that place high demands on pumps.

On May 2, 2019 ProMinent carry out the opening of its new facilities in Mexico located at the north of Queretaro City.

After the five-day trade fair, Deutsche Messe AG concluded that everything had gone very well. Dr. Jochen Köckler, Chair of the Board at Deutsche Messe AG, said that “Hannover Messe 2019 has demonstrated that it is the most important platform internationally for all technologies associated with industrial transformation”. Torsten Silkenbeumer, Key Account Manager for Process Technology at ProMinent, confirmed that the event had been a success from ProMinent’s standpoint too: "Our involvement in the Pump Plaza produced numerous leads in Germany and abroad. Alongside our metering and process pumps, visitors were especially interested in our web-based solutions for digital fluid management.”

Markus Rösch, Divisional Manager for Pool and Wellness at ProMinent Deutschland GmbH, summed up interbad 2018 with great positivity: “We had high numbers of visitors to our stand and a huge amount of interest in our new products on all four days. All in all, it was a successful international event with a lot of high-quality conversations."
