Extrusion International USA 2-2022

51 Extrusion International 2/2022 PROCESSING the blades during production. This allows higher equip- ment availability, elongated production runs and thus saves costs. Innovation in strand pelletizing: The PRIMO Plus Flex provides • Shortest unguided length in combination with an en- larged rotor diameter lead to more torque on one hand and to superior pellet quality on the other • Throughputs up to 5,000 kg/h • Pro fi table production due to very high machine avail- ability with wear resistant cutting tools For applications such as pelletizing of base polymers, re- cycling products, processing of highly fi lled compounds or ETPs at different pellet lengths frommicro to LGF, the PRIMO Plus is our fi rst choice for a reliable dry cut strand pelletizing process. All MAAG Group extrex ® gear pumps in x6 class design are completely re-engineered and have redesigned com- ponents, from the shafts through to the bearings and seals, and optimized the interaction of the components. Specially developed gear teeth with low compression al- low very high pressures to be achieved with low shear rates. The result is a further increase in achievable prod- uct quality, volumetric ef fi ciency, as well as production consistency and safety. Claudio Bonafede, General Manager: “Another innova- tion in the market is the MAAG Brain. We are happy to present this stand-alone monitoring system, which is a step forward in the world of Industry 4.0 and Internet of Things (IoT). The system has been developed to monitor pumps and ensure their maximum ef fi ciency during the operation.” At Greenplast inMilan, Italy, fromMay 3-6, 2022, MAAG Group shows integrated solutions for the processing of polymers in the recycling process in hall 14, booth 31, in particular the ERF high-performance melt fi lters from ETTLINGER Maag Pump Systems AG Aspstr. 12, 8154 Oberglatt, Switzerland MAAG Group PEARLO ® 350 Underwater Pelletizer Pump & Filtration Systems, Pelletizing & Pulverizing Systems, Recycling Systems and Digital Solutions at Greenplast 2022 MAAG ETTLINGERs ERF 350 is a high performance melt fi lter for the fi ltration of heavily contaminated polymer feedstock. The fi lter is self-cleaning with a rotating, perforated drum, through which there is a continuous fl ow of melt from the outside to the inside. A scraper removes the contaminants that are held back on the surface and feeds them to the discharge system. This enables the fi lter to be used fully automatically and without any disruptions over long periods without hav- ing to replace the screen. The advantages: Reliable melt fi ltration, ultra-low melt losses and good mixing and homogenizing of the melts. PEARLO ® 350 EAC with liquid-heated die plate for high capacities: The underwater pelletizing system PEARLO ® 350 EAC is especially designed for high throughputs of like 18.000 kg/h of Virgin Polymer production. The unique cutting blade design and optimum water and material fl ow conditions within the cutting chamber provide not only ideal and homogeneous cooling effects but also out- standing pellet quality. Another innovative design fea- ture of the PEARLO is the cutting blade advance system, which permits axial movement of the cutter shaft result- ing in a precise blade advance as well as a regrinding of MAAG Ettlinger’s ERF 350 high performance melt fi lter
