Explosion Proof, Atex Area, Micro Annular Gear Pump HNPM mzr-6359 Ex is Hermetic Inert Pump by HNP Mikrosysteme for use in chemical and process technology at Thomson Process Equipment and Engineering.
HNPM Atex Pump Ex Series HNPM mzr-6359 Ex Micro Annular Gear Pump offers Precision Dosing, Low Pulsation Small Volume Dosage at High Pressure for broad viscosity range of liquids including watery solutions, solvents, oil and gels. For pumping even corrosive and aggressive liquids.
HNP Mikrosysteme micro annular gear pump HNPM mzr-6359 Ex covers the flow range 0.048 - 225 ml/min. The highly precise, low pulsation small volume dosage even of non-lubricating liquids or at high pressure, the compact design of this Ex-pump, the broad viscosity range and the small measurements are unique features of this pump series.
The HNP Mikrosysteme HNPM mzr-6359 Ex 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.Thanks to the use of rotors and functional elements being made of ceramics, a magnetic coupling, and case components made out of alloy C22, this pump will take up any challenge in the chemical industry applications.
