BKG® BlueFlow™ Reactor Discharge Pump Types RP-LE / RP-LF

BKG® BlueFlow™ Gear Pump types RP-LE / RP-LF are mainly designs for the discharge of low to medium viscosity melts, such as adhesives or polyamides out of reactor vessels or mixing and storage tanks. Additionally, they are used for low viscous materials in extrusion processes.

  • Discharge pumps designed specifically for low to medium viscosity melts
  • Pump inlet optimized to maximize filling performance through various channel geometries
  • Drive-side threaded shaft seal with stuffing box packing leads to reduced operating costs
  • Borings for melt pressure and melt temperature sensors integrated in the pump housing provides enhanced process diagnostic capabilities
  • Optimized operating clearances to process polymers with a low viscosity

Type: RP-LE
Application: For the discharge of low to medium viscous melts
from reactor vessels and tanks
Feature: - Process-specific connection geometry
- Special sealing system
Optional: Liquid tempered

Type: RP-LF
Application: Provides the same advantages as the RP-LE model
with the additional benefit of heating the pump with a fluid

Old vs. New

  • Higher specific volume in a smaller housing
  • Metric system
  • Two melt immersion points inlet / outlet
  • Dynamic seal system with stuffing box
