Progressing Cavity Pump / Mono Pump / Screw pump - Netzsch NU40

The Netzsch NL progressing cavity pump (also known as a mono or screw pump), engineered for the continuous and gentle transfer of challenging media. This pump operates on the well-proven progressing cavity principle, consisting of two primary components: a precision-machined helical rotor and a resilient elastomer stator. The rotor features a single-helix design with a large pitch, deep thread profile, and small core diameter. As the rotor rotates eccentrically within the stator, sealed cavities are formed that convey the product continuously and pulsation-free from inlet to outlet. This pump is previously used in a dairy factory. Motor: 1,1 kW - 220/240 - 380/415 V - 50 Hz - 1.410/1.700 rpm - 4,5/2,4 A. Connections on the inlet/outlet: DN 50. Estimated capacity (based on motor power, gear reduction unknown): +/- 1.000 ltr/h.

Key Advantages:

• Valve-free design with stable, proportional flow rate relative to rotor speed.
• Excellent self-priming and suction capability.
• Suitable for inhomogeneous, viscous, abrasive, gaseous, and solids-laden media.
• Gentle product handling, ideal for shear-sensitive materials.
• Capable of dosing applications.
• Designed for Cleaning-in-Place (CIP).

Limitation:

• The pump must not be operated dry. Even short periods of dry running may result in stator damage.
