Precise metering technology for clean water worldwide

To provide clean water on a permanent basis, precise metering, reliable technology and digital integration are required.
With the magnetic diaphragm metering pumps gamma/X and the motor-driven diaphragm metering pumps sigma, ProMinent offers two systems that have proven themselves worldwide.
Around 1.6 million ProMinent pumps are in continuous use worldwide – in municipal facilities as well as in industrial processes.
"Clean water is one of the most valuable resources of our time. Our technology helps to secure this resource worldwide – through precision, digital networking and solutions that are already shaping the future of water treatment today," said Andreas Zühlcke, vice-president product management & marketing at ProMinent.
The gamma/ X meters disinfectants such as sodium hypochlorite or pH correction agents accurately and consistently.
Its digital control automatically adjusts the metering quantity to the respective flow rate. Integrated pressure and air detection supports stable operation. The pump can be integrated into existing systems and monitored centrally via interfaces such as Profibus, Profinet or Modbus.
The sigma is used where high flow rates and robust construction are required – for example, when adding flocculants, biocides or pH correction agents. Chemical-resistant materials and the patented multi-layer safety diaphragm enable reliable and low-maintenance operation.
This makes the sigma particularly suitable for demanding applications in industrial and municipal water treatment.
From drinking water plants in Europe to industrial facilities in Asia and sewage treatment plants in South America – ProMinent pumps gamma/ X and sigma are in use worldwide.
Their digital networking allows continuous monitoring and adjustment of processes, making operation safer and more efficient.
