Beschreibung
Ex-pumps for application in chemical and process technology The micro annular gear pump mzr-7209 Ex covers the flow range 0.048 - 226 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 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. Advantages Ex-certification ATEX conform with EU Directive 2014/34/EU High dosage precision precision CV < 1 % at low volumes Compact dimensions length < 295 mm, including Ex-motor Broad viscosity range methanol, solvents, adhesives, grease, gel Long service life wear-resistant tungsten carbide Low pulsation delivery, low shear...
