Gear pumps in the polymer production process
Polymer processes for the production of plastics place high demands on the melt pump, which gently and efficiently transports the high- and low-viscosity plastic melts through the system. MAAG gear pumps enable oligomers and pre-polymers and the finished polymers (plastic melts) to be conveyed reliably in one flow, even at low filling levels and with high vacuum on the suction side of the melt pump. The combination of low compression pressures in the gear pump against high pressure and low shear of the plastic melt is made possible in a gentle way owing to a specially developed toothing in the gear pump.
MAAG introduces the vacorex®-x⁶ class gear pump. vacorex⁶ fulfills ideally modern polymer production processes which require pumps that can discharge at high pressure despite very low fill level and high vacuum conditions in the reactor/devolatilization vessel. MAAG vacorex⁶ process a wide range of different polymer grades without affecting their quality. Reliable, requiring little maintenance, and… [...]
Polymer processes require pumps that gently process both high and low viscosity plastic melt through the system. Specially designed low-compression teeth allow the thermorex®-x⁶ class transfer, booster or metering gear pump to achieve both high pressure and low shear. The plastic melt is conveyed with a constant, precise flow even at high discharge pressures —… [...]
Processes in the manufacture of polyolefins require high-pressure gear pumps which build up pressure for the units after the compounder. The new performance driven geometry of polyrex® x⁶ class results in high throughput rates at high flow rates and low shear stress. polyrex⁶ can convey low viscosity polymers where earlier pump generations failed. Thanks to… [...]
Polymer processes in the polymer industry require units that gently discharge low and high-viscosity plastic melts from reactors and degassing equipment. The MAAG polymer extraction pump systems and viscorex® transfer gear pumps feature the excellent fill behaviour and short residence times that make them the ideal solution for such polymer applications. Their high efficiency and… [...]
Polymer processes and polymer applications require polymer transfer pumps which will constantly and reliably feed oligomers and prepolymers through the system. The liquid polymer pump design is highly suitable for low viscosity. Thanks to thermorex® TRP and TRO, reactors no longer have to be pressurized. The good efficiency and long service life increase the efficiency… [...]
