Flushing Strainers Self cleaning suction strainer

Akin to the blow down feature of a Y strainer, flushing strainers are a variation of a standard simplex basket strainer having a special “bottomless” basket which allows accumulated particles to “flush” from the drain port when a valve is opened. We can include the manual or actuated valve within our scope of supply.

Although the actual flushing of the strainer basket typically requires less than 1-2 seconds, if you use an automated valve the flushing time will be dependent upon the cycle time of the valve actuator, which is typically 18 to 30 seconds from closed, to open and then back to closed.

Although tempting and beneficial for some applications, automating the flushing feature will likely require a custom programmed PLC to allow for actuation on a timer or differential pressure basis and to handle upset conditions as would be the case if a screen has embedded particulate and thus not adequately reducing the differential pressure after a flushing sequence. The added complexity and cost associated with such controls is characteristic of our backwashing strainers which would provide the added benefit of cleaning the strainer screen and no just flushing collected debris.

So unless your application involves very low loads of hard materials such as pipe scale, automating the flush cycle is probably not practical.
