Introduction 

 
A self-cleaning strainer is a device installed in a pipe-
line to remove dirt and other unwanted debris from 
fluids.  Straining is accomplished by directing the fluid 
through "sized" openings in perforated straining ele-
ments.  Self-cleaning strainers have integral back-
wash systems designed to isolate and clean a small 
portion of the element while the remaining area contin-
ues to strain normally.  During operation, fluid flow 
through the strainer is continuous.  A small quantity of 
"clean" fluid is used to wash the element and then 
carry the concentrated debris away from the strainer 
through the backwash system. 

Read all instructions before installation or 
operation of equipment.  Failure to comply 
with these instructions could   result in 
bodily injury or property damage.
