The optimal pump for highly viscous, compacted and crumbly substances that have a tendency to bridge!

NEMO, SP, Funnel-Shaped, Progressing Cavity, Pump, Netzsch

For highly viscous, compacted and crumbly substances that have a tendency to bridge, the NEMO® SP Progressing Cavity Pump is the optimal solution. The NEMO® SP can be used in nearly all branches of industry to provide continuous, pressure-stable, gentle and low-pulsation conveyance with dosing in proportion to rotation speed. The special features of this model include the patented, horizontally positioned feeding screw, the integrated bridge breaker and the enlarged rectangular hopper. Optimal feed into the conveying elements is guaranteed by means of the coupling rod with this feeding screw and the conical force-feed chamber. The bridge breaker prevents bridging and makes the mixing of aggregates possible. The funnel dimensions can be adjusted to the individual application case. The design of the NEMO® SP with bearing block and free shaft extension makes it possible to use any drive type.
