The micro annular gear pumps mzr-2909 Ex, mzr-4609 Ex, mzr-7209 Ex and mzr-11507 Ex cover the flow range from 0.003 to 1152 ml/min. The highly precise, pulseless small volume dosage even of non-lubricating liquids or at high pressure, the compact design of the Ex-pumps, the broad viscosity range and the small measurements are unique features of this pump series. The pumps are applied in the field of chemical technology and process engineering and are suitable for both continuous delivery and discrete dosage of watery solutions, solvents, bases and other viscous liquids. Accessories extending the operating parameters of the devices are available.
