The xLC unit was added to the product portfolio of the Nemo progressing cavity pump from Netzsch. This triples the service life of the pump, particularly when conveying difficult, abrasive media. When wear occurs in the rotor-stator system, this new unit allows the performance of the pump to be re-established by adjusting the preload between the conveyor elements.
It is important for the xLC stator adjustment system that the elastomer in the rigid metal sleeve of the stator is flexible, which was made possible with the development of the proven iFD stator 2.0. If the stator has to be adjusted due to declining performance of the pump, the setting nuts of the system are adjusted, compressing the elastomer insert in the metal housing once again. A scale with seven defined stop points facilitates gradual adjustment of the stator with only two setting screws while also showing the remaining potential until stator change.
