The LP_-SeriesTM design is the most recent, state-of-the-art self-cleaning screen filtration technology available today.  The complexity and cleaning efficiency of any self-cleaning screen filter is in the mechanical system that drives the cleaning process.  The LP_-Series patented Bi-Directional Hydrodynamic Drive (BHD) mechanism is the simplest and most efficient in design resulting in:

  • fewer moving parts (no limit switches or pistons reversing the cleaning mechanism),
  • simpler controls,
  • lowest flush flow available,
  • greater cleaning efficiency, and
  • lower maintenance requirements


The LP_-Series also offers:

  • a lower cost than standard V-Series filters
  • victaulic quick installation

The 12 to 15 second flush cycle is automatically initiated when a pressure differential across the screen increases to 0.5 bar (7 psi).  The filter remains on-line and the filtration process is uninterrupted during the brief cleaning process.  The flush discharge is the lowest available resulting in minimal waste.
