Additional Details

Operation

  1. Unfiltered fluid enters the strainer through the inlet and flows into the center of wedge wire strainer screen.
  2. Particulate and debris will collect against the screen as clean fluid passes through.
  3. As more unwanted particulate builds up against the screen, the differential pressure will increase and the cleaning cycle will initiate automatically at desired setpoint.
  4. The internal scraper will rotate against the screen removing all unwanted buildup which collects at the bottom sump.
  5. Near the end of the scraping cycle, the purge valve is automatically opened to flush out the sump.
  6. During the scraping operation clean fluid will continue to pass through the vessel.
