BKG® BlueFlow™ High Pressure Gear Pumps

The BKG 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
