Suction Strainers for Hi-Flow Applications

Suction Strainers for Hi-Flow Applications

Suction strainers are far less restrictive than other filtration devices within the system because their sole purpose is to protect the pump. Therefore, “straining” should take the place of “filtration.” These terms can be considered synonymous but there is a definite difference. Straining generally refers to a filtration level of 200 mesh (74 micron) or coarser.
 
One may believe that if there is a requirement for a pump to properly strain the fluid in a 400-gpm application, you can merely tee 4-100 gpm strainers to cover the flow rate. However, every time fluid travels around a bend or corner in the line, it creates an additional, unwanted pressure drop. Fewer bends equal lower pressure drops. Therefore, the answer would be to install one larger strainer that can handle 400 gpm.
 
OFCO OS Suction Strainers are available in 5.9” and 8.1” sizes with flow rates from 200 to 400 gpm.
