BKG® BlueFlow™ Extrusion Pumps Types EP-SE-EO / EP-SF-EO

BKG® BlueFlow™ Gear Pumps types EP-SE-EO / EP-SF-EO are used in extrusion, compounding and polymerization processes.

The gear pumps help optimize the process, so the extrusion line produces optimal quality with the high throughput possible. The gear pump has a rheological optimized inlet and outlet geometry to guarantee a very controlled transport of the material. Temperature and pressure sensor ports are included in the pump housing.

Benefits:

  • Reduction of stress on the extruder by means of shifting the job of building pressure to the gear pump
  • Reducing extruder head pressure may yield increased throughput rate leading to maximized production efficiency
    • Elimination of output variations and pressure pulsations
    • Improves product quality
    • Reduces scrap and product defects
    • Saves polymer usage
  • Allows the use of up to 100% regrind in production with consistent metering
  • Improvement of the dimensional accuracy in the production of sheets and profiles
  • Optimizes the surface and optical quality in the production of films, sheets and profiles
  • Increased product quality in homogeneity and pellet size in compounding applications

Features:


Type: EP-SE-EO

Application: Shear sensitive plastics, e.g. PMMA, PET
Feature: Smaller flow channels to reduce the residence time
Cooled sealing system

Type: EP-SF-EO
Application: Provides the same advantages as the EP-SE-EO
model with the additional benefit of heating the pump
with a fluid

 

Old vs. New

  • Metric system
  • Two melt immersion points inlet / outlet
  • Different shaft sealings available: air or fluid cooling,
    finned seal and dynamic seal
