When metering liquids, gas bubbles and pressure fluctuations are the main causes of metering inaccuracies. Outgassing media can also block the conveying process completely. Intelligent functions and model-based control behaviour of the gamma/ X and XL solenoid-driven diaphragm metering pumps provide a remedy.

Safe process, safe handling, optimal dosage

In the Flanders region, more than 83% of the wastewater is treated using the most modern methods. The project has a positive effect on the water quality of the Schelde and Maas and makes a significant contribution to keeping the North Sea clean. Aquafin, which was founded by the Flemish government around 30 years ago, plays a key role in this.

Usually when you least expect it, chemicals run out. With the new suction lance from ProMinent, this is a thing of the past. The lance does not only ensure a reliable removal of liquids, but also monitors the current fill level at the same time.

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.
