HNP-Mikrosysteme - Model MZR - 2509X2 -Micro Annular Gear Pump
The micro annular gear pump mzr-2509X2 Ex cover the flow range 0.0015 - 6 ml/min. The highly precise, low pulsation 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 dimensions are unique features of this pump series. The pumps are applied in the field of chemical and process technology and are suitable for both continuous delivery and discrete dosage of watery solutions, solvents, oil and other viscous liquids. Accessories extending the operating parameters of the device are available.
