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 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.
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 Sigma control type is a smart motor-driven metering pump that is setting new standards in terms of productivity, reliability and safety.
The peristaltic pump DULCOFLEX DF2a meters chemicals functionally, cost-effectively and quietly – ideal for use in swimming pools, hot tubs, and in spa and wellness facilities.
The valveless peristaltic metering pump DULCOFLEX DFYa delivers precise, linear and reproducible metering in all process conditions. It is highly suited to outgassing, viscose, shear-sensitive media, possibly containing particles – ProMinent is therefore setting new standards in metering with peristaltic pumps.
DULCOFLEX DFXa meters outgassing, viscous, abrasive or shear-sensitive media and is setting new standards in metering. Linear and reproducible metering (± 1 %) is guaranteed with this peristaltic pump under all process conditions. Hose replacement is a very simple process.
The hygienic design version of the sigma diaphragm metering pumps is optimised in terms of dead space, features as few gaps as possible and has smooth, wetted surfaces for flexible and easy use in hygienically sensitive applications.
