NETZSCH introduces screw pumps for a wide variety of media
An application in media delivery can often be handled by using different pump types. However, optimum results and material-preserving transport require ra-ther exact matching of the pump to the different parameters such as viscosity, temperature, NPSH value or shear sensitivity. NETZSCH Pumpen & Systeme GmbH therefore supplements its portfolio of progressing cavity pumps and rota-ry lobe pumps by three model series of compact screw pumps: the NOTOS two, three and four-spindle pumps. Depending on the type, they are suitable for non-lubricating substances at high pressures up to 80 bar and temperatures up to 300 °C. They thereby cover a wide range of application areas – from lubricants to sealants and on to bitumens or resins. Thanks to special materials, hydraulic compensation and geometry – optimised through FEM simulations – all NOTOS pumps are designed for top efficiency and operating life. The new series was introduced at this year's Achema trade fair in Frankfurt/Main.
