Polyrex⁶ PR
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.
Suitable for Masterbatch, Compounding

Together with the extrex6 we can also provide the drive unit as a package. For optimum performance it is important the drive units are calculated to the application requirements and as accurately as possible. Maag has both the experts and high level modeling programs to assure just the right combination of torque, speed and efficiency.
Newly introduced is our Dual Drive unit designed for high abrasive, recycling and Fluoro polymer applications. The Dual drive unit is a Maag own development to bring up an economical and effective solution for processes requiring minimum gear toothand loading.
ViscosealAvailable for high viscous fluids
The viscoseals are available for highly viscous fluids which are used for extrusion gear pump systems. The seal is contactless and dynamic. It has a simple design and has only one sealing part. A cooled model is available for the polymer extrusion industry is available and it is virtually maintenance free.
