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.

flushing strainer model SSGFV 316SS 3" with 1" flanged drainThe time required for flushing varies based upon the operating pressure and particle characteristics, but is typically only a few seconds.

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

Advantages:

  • Relative low cost and cost effective for small strainer sizes

  • Larger open area ratio than a Y-strainer equates to lower pressure drops across strainer and less frequent flushing

  • Quick delivery, usually within 2-4 weeks

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.
