General Industrial: Plastics & Polymers

For 70 years‚ Zenith Pumps‚ a Colfax Business Unit‚ has supplied the plastics and fiber industry with exceptional metering products for the processing of polymer into fiber‚ film‚ profile and sheet. In 1926‚ Zenith Pumps developed the first precision metering gear pump for the extrusion of acetate rayon‚ which became the foundation for the entire synthetic fiber industry.

The Polymer Extrusion Pump‚ PEP-II’s‚ unique positive displacement design provides consistent‚ accurate polymer delivery under varying extruder output conditions of pressure‚ temperature and viscosity. With the PEP-II providing the pressure between the extruder and the die‚ extruder parameters can be configured to provide a homogeneous melt at increased throughputs and tighter gauge tolerances.

Zenith PEP II pumps provide precise‚ pulseless‚ repeatable metering of fluids and are available in a range of capacities and types covering virtually every polymer utilized in the plastics industry including : polyester‚ polypropylene‚ nylon‚ acrylic‚ cellulosics‚ spandex and many specialty fibers.

They offer:

  • Improved Dimensional Stability
  • Controlled Melt Quality
  • Increased Production
  • Reduced Raw Material Usage
  • Eliminates Surging and Screw Beat
  • Crowned Root Gear Design
  • Streamlined Operation and Startup
  • Extended Extruder Life
  • Lower Operational Costs
