polyrex⁶ PR

Pressure increasing pump for the polyolefin industry

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 increased pump performance, the specific conveying capacity is 50% higher compared to same housing size pumps of older generations. For debottlenecking existing plants, MAAG offers alternative housing designs with matching interfaces to older pump generations.
