BKG® BlueFlow™ Masterbatch Pumps Type MP-SE/MP-SF

BKG® BlueFlow™ Gear Pump types MP-SE / MP-SF are suitable for sensitive plastics and processes that require frequent product changes. The Masterbatch version allows the discharge of lubrication flow out of the gear pump and therefore out of the process, giving you the power to control the purging of our process when necessary.

Benefits:

  • Lubrication flow can be discharged to the outside during the material change by means of a pair of manual valves. The valves are designed so that they not only lock the recirculation channels in the bypass position but also clean the recirculation channels by flushing the material in them; eliminating "Black Specks" and / or degration
  • Raw materials savings due to fast color changeovers
  • Minimizes the product rejects by reducing the time between color changes
  • Reduced self-cleaning time during color or material changes, thus minimizing contamination 
    and material waste
  • Increased throughput due to reduced cleaning time
  • Suitable for residence time critical or thermally sensitive polymers, such as, PC or PMMA
  • Suitable for optical applications
 
Features:
 

Type: MP-SE
Application: - Sensitive plastics, e.g. PC, PMMA
- Frequent changes of color and product
Feature: Removal of the bearing lubrication flow
Optional: Forced leakage possible

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

 

Old vs. New

  • Consistent global design
  • Metric system
  • Higher specific volume in a smaller housing
  • Two melt immersion points inlet / outlet
  • Different shaft sealings available: Air or fluid cooling,
    finned seal and dynamic seal
