Netzsch NEMO® BY Progressing Cavity Pump


NEMO® BY Progressing Cavity Pumps convey a wide array of substances or very precisely meter substances in numerous industrial applications. From low viscosity substances to products barely capable of flowing, with or without solid content, shear-sensitive, sticky or abrasive – with the NEMO® BY, even difficult substances are pumped gently and with low pulsation.

In block construction with a direct-coupled drive, this NEMO® pump is particularly compact and economical. The NEMO® BY also offers you low investment and low operating and maintenance costs. Four rotor/stator geometries are available to cover a wide range of products and applications. Contact us and we will help you find the optimal solution for your application.
