principle of operation
Metering pumps are oscillating displacement pumps. An exactly defined volume of liquid is drawn into the displacement body on the reciprocal stroke and forced into the dosing line on the compression stroke.
ACCURACy and simplicity in function
Over one million of our 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.

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
Specify power supply
If pump capacity is unknown, our experts would be able to determine capacity according to product requirement needs per unit of dosage.
