BKG® HiCon™ K-SWE-4K-75/RS Double Piston Backflush Screen Changer

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

Backflush:
3 screen cavities (75%) in the process

Screen change:
During a screen change one of the screen cavities (25%) is removed from the process, allowing for three of the screen cavities (75%) to remain in operation

The K-SWE-4K-75/RS is suitable for almost all processes and materials. It is used in pressure constant processes (e.g. strap, film, fiber, strand pelletizing). It can manage processes with a high proportion of contaiminates (recycling) and enables process runs to continue without any system shutdowns while changing the screen.

Benefits:

  • Reduced spare part costs recognized due to the integrated self-cleaning (backflush) process, allowing screens to be used repeatedly
  • Fully automated backflush and venting procedure (via PLC) reduces operator intervention
  • Significant reduction in operating costs (screen & labor costs) is ensured by up to 100 backflushes
  • 4 screen cavities provide a large filter area in a comparably small housing and minimize the number of self-cleaning backflushes at the same time

 

Features:

  • ‚During the process steps “backflush” and “screen change,” 
  • 3 of 4 screens remain in production at all times (patented 75% technology)
  • Backflush function
  • 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
