Due to the optimisation by means of the High Efficiency Unique Design (HEUD) concept, three screw pumps convince with a high efficiency. In addition, continuous delivery with low pulsation and a flow of the medium with minimal turbulence is ensured. This results in gentle product handling. It is assured by means of state-of-the-art technology, precise tolerances and an optimised screw profile. In addition to a drive screw that transmits torque via a thin hydrodynamic film, 3NS three screw pumps have two rotating, intermeshing driven screws. This makes them particularly suitable for non-abrasive and non-corrosive media as well as for liquids with low to medium viscosity, such as lubricants. Through an optional upgrade, NOTOS® multi screw pumps meet the American Petroleum Institute (API) standards relevant to the oil & gas and petrochemical industries. Furthermore, thanks to the wide range of materials, they are versatile and can be used in a wide variety of applications. In addition to grey cast iron and chrome-nickel steel, they are also available in duplex, superduplex or hastelloy steel. This ensures low maintenance and thus low life cycle costs.
Nitrated in alloy steel or in stainless steel. The HEUD (High Efficiency Unique Desgin) provides excellent performance.
2 Housing with optional heating jacket
Thanks to the optional heating jacket, the conveyed medium can be kept at a certain level. In addition, the liner is replaceable and available with various connection configurations, for example top top, side top or in line.
3 Bearing Bushes
Internal bearing bushes helps to support radial loads.
4 Mechanical Seal
Under suction pressure just one mechanical seal is required for the 3NS. Magnetic drive optional.
