BKG® BlueFlow™ High Pressure Gear Pumps

The BKG® BlueFlow™ MHDP high pressure gear pump is a positive displacement pump which provides a linear polymer output over a wide range of operating conditions.  By locating the BKG® gear pump between your extruder and die, you can directly dial in consistent, repeatable polymer flow rate, while eliminating extruder surge, precisely metering polymer, and building pressure to your die.


  • High pressure pump up to 689 bar (10,000 psi) operating pressure
  • Reduction of stress on the extruder by means of shifting the job of building pressure to the gear pump
  • Increase throughput rate leading to maximized production efficiency
  • Elimination of output variations and pressure pulsations, thus improvement of product quality
  • Raw material savings by means of tighter manufacturing tolerances
  • Reduction of product rejections by means of eliminating the pulsations in the process
  • Improvement of the dimensional accuracy in the production of sheets and profiles
  • Optimization of the surface and optical quality in the production of films, sheets and profiles
  • Increased product quality in homogeneity and pellet size in compounding applications
  • Imperial US-connection geometry 



Type: MHDP
Application: Standard polymers
Feature: Process-specific sealing systems

Application: Has the same features as the MHDP-Type, with the additional advantage of fluid heating
