Gear pumps

When it comes to manufacturing profiles and dealing with strainers, high requirements are placed on pumping consistency and extrusion lines. The new gear pump series extrex⁶ RV/RB from MAAG raises the performance of gear pumps for elastomer extrusion to new levels in terms of both economy and processing technology. Product quality is guaranteed by a stable discharge, the lowest tolerance deviations and achieving process stability in quick time.

Elastomeric processing requires positive displacement devices that gentle convey high viscosity rubber through the system. Specifically designed, low compression tooth design allow the extrex⁶ ER transfer, booster or metering gear pump to achieve both high pressure and low shear.
The rubber compound is conveyed with a constant, precise flow even at high discharge pressures – and this also for extremely dry or sticky compounds, where former pump generations reached their limits due to scorch. Additionally, their anyway high efficiency and long life span will extend unrivaled due to reduced internal friction.

Suitable for Extrusion

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.

Suitable for Resin & Virgin Polymer Production

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

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

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

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
