Maag solutions for raw material production and recycling

Maag’s extrex6 gear pump for plastic and elastomer processing

For the first time at Fakuma, Maag (A6-6202) will be sharing a stand with filter manufacturer Ettlinger, which joined the group in January this year. As a result, the company offers products for applications from raw material production, through compounding, to recycling, all from a single source. The range of products shown extends from a gear pump for high pressures, through a dry-cut strand pelletizer and an underwater pelletizing system for the production of spherical pellets ending with a high-performance melt filter with an extra-fine filtration grade for bottle-to-bottle PET recycling.

Gear pumps

Maag gear pumps, now available in an x6 class version, are designed for particularly high melt pressures, and suitable for a wide range of viscosities. While the focus in developing the EP and EV types was on maximizing pressures and volumes, the model presented at the fair forms part of the more in demand GU line of products. As generally for the x6 versions, Maag has completely revised all its components, from the gears and shafts to the bearings and seals, and has optimized the functional interaction of the components in order to enhance product quality, volumetric efficiency and the consistency and safety of the production process even further.

Pelletizing systems

At Fakuma, Maag presents a Primo 200 E model pelletizer from its WSG dry-cut strand pelletizing systems range for the reliable production of high-quality cylindrical pellets or micro-pellets ideally suited to further processing. Like all the models in the Primo E family, it features a variable system configuration for the processing of soft, brittle or abrasive polymers. Quick tool and roller exchange enable flexible adaptation to specific production demands, delivering optimum flexibility for product changes. The pellets created by this system can be infinitely adjusted in terms of weight and length to the specific task at hand. With a 200 mm draw-in width, it is designed for draw-in speeds up to 120 m/min and a maximum throughput rate of 1,500 kg/h.

The Pearlo® 160 presented at Fakuma forms part of a new family of Maag high-performance underwater pelletizing systems. This product line was developed for the production of spherical plastic pellets. It combines technologies from Gala and Automatik for highly efficient and flexible deployment in high-end applications at throughput rates starting in the single-digit range and extending up to 36,000 kg/h (the 160 model being presented in Friedrichshafen achieves 1,000 kg/h to 6,000 kg/h).

Melt filters

The Eco 200 high-performance melt filter from Ettlinger being presented at the fair is – like the larger Eco 250 version – designed for very free-flowing materials such as PET and PA with pollution severities up to 1.5%, but is also suitable for polyolefins and polystyrenes. Typical applications are compounding and filtration of gels and agglomerates, in particular of aluminium, paper, silicone or PVC constituents from recycled PET bottles. The now available extra-high filtration grade of 60 µm is ideal for bottle-to-bottle recycling, with its extremely high quality demands. Thanks to their efficiency, the Eco melt filters can be integrated directly into PET thermoforming lines, where their throughput rates of up to 1,000 kg/h (type 200) and 3,000 kg/h (type 250) help to improve machine availability and enhance cost-effectiveness.
