Polymer Production Pumps

Gear pumps for industrial processes (grey cast iron) ‒ hydrolub®

Polyrex⁶ PR

Processes in the manufacture of polyolefins like polyethylene and polypropylene require high-pressure gear pumps which build up pressure for the units after the compounder, meaning for extrusion and pelletizing. The new performance-driven geometry of the x6 class of polyrex® results in high throughput rates at high flow rates and low shear stress. Polyrex⁶ can convey low viscosity polymers where earlier polymer metering pump generations failed. The increased pump performance during polymer processing makes the specific conveying capacity 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 polymer metering pump generations.
