BKG® NorCon™ LK-SWE Continuous Double Piston Screen Changer

Normal operation:
2 screen cavities (100%) in the process

Backflush:
Not applicable

Screen change:
During a screen change one of the screen cavities (50%) is removed from the process, allowing for one of the screen cavities (50%) to remain in operation

The LK-SWE is suitable for almost all processes and materials. It can be used for polymerization, compounding, film, pipe, sheet and pelletizing processes. More specifically, all polyolefins and a variety of other temperature stable polymers (e.g. ABS, PS, SAN) and preferably for systems operating at higher throughput rates. The LK-SWE enables process runs to continue without any system shutdowns while changing a screen.

Benefits:

  • Process remains in operation during a screen change, resulting in no disruptions to the melt flow
  • Easy adjustment of the hydraulic device via the hand control or solenoid valves
  • Optional fully automated venting procedure (via PLC) reduces operator intervention
  • Large filter area in a comparably small housing due to oval-shaped screens

 

Features:

  • Oval-shaped screens 
  • Optimized flow channels utilizing rheological data
  • Wear-free metallic sealing system – no additional seal required
  • Easily integrated into the line controls
  • Includes complete guard system, offering maximized safety for the operators
