How a flushing strainer works

Flushing Strainers

Flushing strainers are a variation of a standard simplex basket strainer, having a special "bottomless" basket which allows accumulated particles to flush out the drain port when a valve is opened.

 

The user supplied valve can be manually or automatically actuated based upon differential pressure or a timer.

Soft particles that become lodged in the strainer perforation or mesh will require manual cleaning to remove.

There are times where the desired open area ratio (OAR) or particle sizes to be flushed require a custom fabricated design.  Sometimes other customizations such as nozzle orientation and centerline above the floor require a fabricated strainer.  These often require 8-12 weeks manufacturing lead time along with drawing approval prior to releasing to manufacturing.
