NOTOS 3NS Three Screw Pump

NOTOS® 3NS Three Screw Pump

Lightweight and Universally Applicable due to Small Footprint

Suitable for use in a wide range of industrial sectors and applications, the self-priming NOTOS® 3NS three screw pumps are true lightweights and have a small footprint.

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.

TORNADO® T2 Industrial Rotary Lobe Pumps

The TORNADO® T2 rotary lobe pump is a positive displacement pump. The pumping action is generated by the contra-rotation of two rotors within the pump chamber which are synchronised externally. The media enters the pump chamber through the inlet port and is carried around the chamber by the rotors to the outlet port where it is discharged.
