Polymer processing, polymer systems, and polymer applications for extrusion in the polymer industry
MAAG specializes in the design and application of blendrex® heat exchangers used to preheat polystyrene melt prior to devolatilization and to cool polyester prior to spinning or pelletizing by polymer processing. blendrex® heat exchangers are problem solvers for many types of difficult heating and cooling polymer applications.
Significantly improve heat transfer rates of polymers and other viscous products. Three to seven times the rate obtainable compared to an “open tube” (no blendrex® elements) design
Provide a shorter product residence time inside the unit
blendrex® tube is a “plug flow” device
Tubes eliminate localized “hot spots”, and provides uniform temperature profile across the tube section
Contain alternating helical twist elements to obtain the high performance capabilities

Chemical pumps and chemical transfer pumps for industrial applications
Magnetic drives are hermetically sealed, thereby guaranteeing that environmentally hazardous, poisonous, and malodorous substances are pumped safely by chemical transfer pumps. The product chamber in the gear pump is completely separated from the environment by a containment shell. The torque is transferred from motor shaft to pump shaft without contact by means of heavy-duty permanent magnets. This design makes the magnetic couplings extremely safe and virtually maintenance-free for the industrial application.
High suction pressures (standard to 25 bar, in special designs up to 200 bar)
Optimized safety and leak sealing
Long service life
Low maintenance costs
Seal for polymer gear pumps and polymer pump systems and applications
High reliability and functionality are crucial for a seal in the polymer application discharging process for guaranteeing optimized product quality and line availability.
