概要（Overview）

NEMO® BY Progressing Cavity Pumps can be used in any area of industry where a great variety of different substances must be pumped or very precisely dosed. From low viscosity media to products barely capable of flowing, with or without solid content, shear-sensitive, sticky or abrasive – with the NEMO® BY, even difficult substances are conveyed gently and under low pulsation. NEMO® BY Pump Features: - Continuous low-pulsation conveyance unaffected by fluctuations in pressure and viscosity - Conveyance volume in proportion to rotation speed with high dosing precision over the entire rotational-speed range - High pressure capability without valves - Location of the mechanical seal directly under the intake port in the pumping space makes external flushing of the seal unnecessary in many applications - Short drive shaft and pump lantern offer high stability for mechanical seal installation - Separate flange bearing and pump base make it easy to change the stator - Variable modular system - Various rotor/stator geometries and a wide spectrum of materials - Robust and compact block construction - Four different joints are available: pin joints, gear joints, V-joints, and pivot joints - Standard mechanical seal, other seals optional - Low noise, low vibration High suction capability up to 9 mWC - Bi-directional - Vertical or horizontal installation - Temperatures from -40°C to 300°C
