ProMinent metering pumps and metering systems

The ProMinent Group provides solutions for metering, water treatment and disinfection, measuring and control as well as digital fluid management for the following industries: Chemical industry, industrial and municipal water treatment, food and beverage industry, treatment of swimming pool water, oil and gas industry and process industry.

The extensive product portfolio consists of metering pumps, peristaltic pumps, measuring and control technology and sensors to manage and meter fluids as well as metering systems for water treatment. For this purpose ProMinent provides all common systems, such as chlorine dioxide plants, chlorine gas metering systems, electrolysis systems, UV systems, ozone systems as well as systems for membrane filtration.

ProMinent metering pumps

ProMinent has boasted the world’s largest range of metering pumps for over 50 years. These are used wherever liquids have to be added to a medium in a defined volume within a defined period of time.

How do metering pumps work?
Most metering pumps are oscillating displacement pumps. An exactly defined volume of liquid is drawn in by the displacement body on the reciprocal stroke and forced into the dosing line on the compression stroke. The pump settings can be changed to achieve consistently accurate metering.

Microprocessor technology since 1988
The accurate control of the pumps is made possible by microprocessor technology. Sophisticated monitoring functions ensure operational reliability and guarantee minimal chemical consumption yet optimum disinfection. Interfaces integrate the pumps into a fully automated process.

Over one million ProMinent pumps are in use all over the globe, delivering reliable, accurate performance under the toughest conditions. Our proven design principles guarantee a high standard of quality and precision.

The product range
Large choice of types, wide range of capacities: from a few millilitres, e.g. for laboratory use, to 40,000 litres per hour, e.g. for use in process engineering.

The technologies in detail:

Diaphragm metering pumps (mechanically deflected diaphragm)
Hydraulic diaphragm metering pumps (hydraulically deflected diaphragm)
Plunger metering pumps
Peristaltic pumps

ProMinent process metering pumps

The best solution for production processes in the petrochemical and oil and gas industries involving risk: process metering pumps from ProMinent.

Zero compromise
There is no room for compromise in high-end applications in the petrochemical and oil and gas industries. Risks associated with the metering of toxic, corrosive and flammable liquids must be fully eliminated. Reliable metering pumps need to be able to withstand very high pressure levels and extreme temperatures. What could be a more obvious solution for very challenging applications than ProMinent cutting-edge technology?

Find the right pump type in four steps

Specify pump capacity in litres per hour [l/h]
Specify back pressure in bar
Find the intersection of these two values and select the pump type that lies nearest to it

ProMinent peristaltic pumps

With a simple functional principle, safe operation and a huge range of applications, ProMinent peristaltic pumps DULCOFLEX are universal solutions.

Our most adaptable pumps
Peristaltic pumps DULCOFLEX are amongst the most adaptable pumps available from ProMinent. They are suitable for a very wide pump capacity range. The smaller pumps of types DF2 and DF4 have been specially designed for metering tasks in swimming pools, hot tubs or spa and wellness zones.

The large peristaltic pumps DFB to DFD are ideal for specific tasks using extremely high pump capacities and pressures in laboratories and in industry. All models are based on a simple operating principle and are extremely safe and easy to use.

ProMinent chemical transfer pumps

ProMinent chemical transfer pumps deliver efficient chemical transfer, transporting liquids from one container into another.

Different media have very different chemical properties so the pumps need different functional principles. ProMinent engineers work hard to make sure that liquid and pump are fully compatible.

They approach every single application with the same ProMinent standards of maximum diligence and quality.

ProMinent metering systems

ProMinent metering systems come fully ready mounted and are ready for immediate use. Sensors, controllers and metering pump form a single unit for minimal installation complexity.

Built to work as a system
Individual components are good for metering liquids, but complete systems make a lot of things easier. One single supplier and contact. No interface problems between the individual components. No need to assemble anything yourself. On request, the complete system is supplied pre-assembled so it’s ready for use and simply has to be connected to the hydraulic and electric supplies. Alternatively, the system can be installed and taken into operation on site by ProMinent technicians.

ProMinent measuring, control and sensor technology

Optimum metering depends on exact measured values. That’s the reason for measuring, control and sensor technology from ProMinent.

The complete solution for your processes
ProMinent manufactures components and systems for metering technology, is a reliable solutions partner for water treatment and with DULCONNEX, provides a cloud-based digital fluid management solution. Using optimised controllers, ProMinent is able to reliably monitor and control processes in public and industrial water treatment. The product range is accompanied by sensors, developed and produced in-house, for the most common measurement parameters, such as chlorine and pH.

ProMinent is a complete solutions provider for the optimum metering of liquids, from reliable pump capacity and the correct measurement of all relevant parameters to precise process control.
