Polymer Production Pumps
For more than 100 years, MAAG has been developing and manufacturing pumps at its headquarters in Switzerland. MAAG is proud of its core competence - the development and production of gear pumps for polymers, chemicals and lubricants and filtration systems for the production and processing of plastics. Today, MAAG is one of the world's leading manufacturers of elastomeric extrusion pumps, thermoplastics, extrusion pumps, industrial pumps, chemical pumps and melt pumps for polymer production. Thanks to many years of experience with production and a deep understanding of polymer production and processing processes, gear pumps of all types can be optimally adapted to individual customer requirements. Technical know-how and the ability to respond to specific customer requirements make it possible to achieve the highest possible efficiency for a given industrial process. The maximum service life of MAAG pumps and melting pumps and the minimum downtime are a great guarantee of the successful operation of industrial plants.
Vacorex⁶ VX
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 robust enough to withstand the rigors of years of operation is vacorex⁶ gear pump the ideal solution for such applications.
Suitable for Resin & Virgin Polymer Production
+ up to 40 % more throughput or + 28 % more pressure and + 11 % more throughput compared to the classic pumps with the same pump size
+ 30 % better heat transfer in the bearings
+ 15 % larger inlet with optimized geometry
+ 8 % better vol. efficiency
- 10 % less energy consumption
Thermorex⁶ TR/TB/TP/TO
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 — and this also for low viscosity products like prepolymers, where former pump generations reached their limits. Additionally, their high efficiency and long service life will enhance the capacity of any given production plant.
Suitable for Resin & Virgin Polymer Production
+ 25 % more wear resistant
- 12 % less energy consumption
+ 10 % better vol. efficiency
- 40 % less temperature increase
+ 30 % better heat transfer in the bearings
- 50 % less pulsation
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.

Viscorex® VR
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 long service life will enhance the capacity and availability of your polymer production line. viscorex® transfer gear pumps efficiently convey plastic melts with a constant, precise flow.
Suitable for Resin & Virgin Polymer Production
Excellent fill behaviour due to optimized inlet geometries
Optimized flow channels
Gentle treatment of polymer melts thanks to special gear teeth with low squeezing power
High overall efficiency and hence minimized friction thanks to pioneering gear and bearing technology
Low pulsation pumping even at high differential pressures
Compact design
Thermorex® TRO/TRP
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 of your production plant with polymer transfer pumps from MAAG.
