Metering Pumps for Polymer Extrusion

Extrusion pumps for polymer processing applications
GC, GE, and GE1M Series

Ever smaller product tolerances characterize the development, i.e. for capacitor foils, packaging films, high-end monofilaments, drawn tapes, gas pipes, window profiles, etc. Our extrusion pumps optimize the polymer extrusion process allowing for precise pressure build-up and metering of polymer in extrusion lines. The use of extrusion pumps is particularly advantageous wherever recycled materials are processed.

Extruders are relieved and are therefore subject to less wear-and-tear. Extrusion pumps offset the impact of various material viscosities. Barmag extrusion pumps is a reliable and durable solution for many extrusion systems within the plastics-processing industry as well as in polymer plants for throughput increase, metering and compensation of pressure fluctuations. Barmag offers a comprehensive extrusion pumps portfolio from a single source with capacities ranging between 4,7 and 12.800 cc/rev.

Applications

  • Manmade Fibers
  • Film Extrusion
  • Sheet Extrusion
  • Pipe Extrusion
  • Profile Extrusion
  • Compounding
  • Granulation
  • Recycling Lines

GC Series – Standard extrusion pump

Features

  • High pressure uniformity thanks to straight bevel spur gearing
  • Low power consumption
  • Low temperature increase
  • Low shear of melt
  • High operating reliability
  • Reliable sealing systems
  • Long service life
  • Available with individually designed drive unit

GE Series – High speed extrusion pump

Features

  • Improved gear design resulting in less shearing areas and therefore lower melt temperature increase Higher operating speeds of the pump are possible due to improved gear design
  • Smaller GE Series pumps can be used while maintaining the same throughput as a similar GC Series pump
  • Up to 15 % energy savings compared to our GC Series

GE1M Series – Extrusion pump for easy interchangeability

Features

  • Common industry design for easy interchangeability and compatibility in various extrusion lines
  • With heating cartridges
  • High pressure uniformity and gentle melt treatment thanks to straight bevel spur gearing
