An application in media delivery can often be handled by using different pump types. However, optimum results and material-preserving transport require rather exact matching of the pump to the different parameters such as viscosity, temperature, NPSH value or shear sensitivity. NETZSCH Pumpen & Systeme GmbH therefore offers 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 bitumen or resins. Thanks to special materials, hydraulic compensation and geometry – optimized through FEM simulations – all NOTOS® pumps are designed for top efficiency and operating life.
