When Prof. Dr. Viktor Dulger dared to take the step into independence in 1960, no one could have guessed what would come of it. From the foundations built 60 years ago, the ProMinent Group has developed into one of the world's leading manufacturers in the field of dosing technology and water disinfection.

In the fight against the corona virus, researchers are working against time: a vaccine must be developed, tested and approved as quickly as possible. For this reason, one of the world's largest service providers for medical research contacted ProMinent to optimise special metering tasks.

The effective disinfection of surfaces plays the central role in the containment of the corona virus. With our electrolysis systems, the highly effective disinfectant can be produced directly on site. The North Italian civil defence is already benefiting from this.

To combat the spread of the coronavirus in the Chinese city of Wuhan, several temporary hospitals were built in a very short time. ProMinent China donated two chlorine dioxide systems for water treatment for one of them.

At aquanale 2019, ProMinent's stand showed how swimming pool operators can ensure clear, pure swimming pool water with energy-saving and environmentally-sound solutions. “All in all, a successful, international exhibition. We are very happy!" said Harald Jarc, Managing Director of ProMinent Deutschland GmbH, of aquanale in Cologne, which attracted a large number of visitors. He added: "At this year's trade fair, we entered into a lot of quality discussions with existing and potential customers from Germany and abroad. On the first day of the event, a lot of people were drawn to our stand by the presence of Sarah Köhler, World Champion in the 1500 m freestyle. The friendly swimmer from Heidelberg signed give-aways and chatted to existing customers and potential customers about water quality and how it impacts on performance, success and health.”

BrauBeviale 2019 was best summed up by Andrea Kalrait, who manages the event: “Fantastic atmosphere at the Nuremberg Exhibition Centre: numerous new contacts from home and abroad, initial business contacts and closing of deals: plenty of good food and drink”. This was confirmed by Robert Günther, Divisional Manager for Food & Beverage / Potable Water at ProMinent Deutschland GmbH who added: “Our products ensure that the food and beverage industry is always playing it safe. Our products allow food and drink to be produced, brewed and bottled hygienically.”

As sponsor of the swimming talent Sarah Köhler we congratulate her and the German Open Water Relay on the gold medal!

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.”
