viscorex® VR

Extraction pump for the polymer industry

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.

Advantages

  • 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
