Metering pumps offer a high degree of accuracy and are used in a wide variety of applications where precise volumes of liquid are required to be moved in a specified time. A metering pump is a subset of the positive displacement pump type and discharges a known volume with every revolution or cycle. Cole-Parmer's range of metering pumps can cover flow rates from 1 nL/min to 225 LPM with pressure options up to 345 bar.
Cole-Parmer offers a range of metering pump categories, including diaphragm pumps, gear pumps, peristaltic pumps and piston pumps.
