Metering Pumps

How do metering pumps work?
Most metering pumps are oscillating displacement pumps. An exactly defined volume of liquid is drawn in on the reciprocal stroke of the displacement body 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
Microprocessor technology allows the pumps to be controlled with accuracy. 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 actuated diaphragm)
- Hydraulic diaphragm metering pumps (hydraulically actuated diaphragm)
- Plunger metering pumps
- Peristaltic pumps

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
