Metering systems and pumps

Solenoid-Driven Metering Pumps

Solenoid-driven diaphragm metering pumps are available in capacities ranging from 0.74 to 75 l/h at a back pressure of 25 to 2 bar. To be able to meter almost any liquid chemicals.

Motor-Driven Metering Pumps

Motor-driven metering pumps need to be robust, reliable and able to run on their own without supervision.

Process Metering Pumps

Reliable metering pumps with possibility to withstand very high pressure levels and extreme temperatures. Used in high-end applications in the petrochemical and oil & gas industries.

Peristaltic Metering Pump

Peristaltic metering pumps are used in a capacity range of between 10 ml/h and 410 l/h. They pump against a pressure of up to 8 bar. Known for the incredible durability and wide-range of chemical compatibility of the high-performance tubes liquids.

Metering systems

The standard metering systems DULCODOS® are ready-for-use, ready-mounted systems where all components are perfectly matched to each other to ensure trouble-free operation.


Metering sensors and controllers


Monitoring a limit value or building a closed control circuit is easy with our sensors – in an enormous range of measuring applications. The product family DULCOTEST® is application-based and ensures precise measuring of a wide range of values. The measured values are delivered in real time and can be flexibly connected to the various process interfaces via bypass, immersion or installed fittings.


ProMinent measuring and control instruments have been specifically adapted to particular applications. They are available in different performance classes and can be integrated in every process environment.
