NETZSCH pumps cover many industries with their efficient and unique design
Flexible, efficient, reliable: NOTOS® multi screw pumps serve many industrial sectors and applications. NOTOS® pumps are designed to handle low to highly lubricating liquids with low to high viscosity, as well as shear-sensitive or chemically aggressive media.
The pumps have been optimised using the High-Efficiency Unique Design (HEUD) concept to give you maximum performance. Your satisfaction is always our top priority. That is why we offer you a wide range of materials. Our range of metallic materials extends from grey cast iron and chrome-nickel steel to duplex, super duplex or Hastelloy steel. We promise you Proven Excellence - outstanding performance in all areas.
The technology of the multi screw pump
The multi screw pump is a rotating positive displacement pump in which the shape of the rotors resembles a screw. It consists of two or more counter-rotating rotors and a housing that encloses the rotors.
The rotors are designed with a regular, thread-like profile and mesh with each other like cogwheels. The cavities created by these three construction elements form the conveying spaces. When the rotors rotate, they move out in one machine direction and convey the medium from the suction side to the pressure side. The helical design also reduces noise compared to straight-toothed gear pumps. This significantly reduces your noise level in production. In addition, this type of pump is particularly suitable for incompressible, even viscous media for generating high pressures.
