Fabricated Duplex Strainers

Double Basket Strainer

Fabricated duplex strainers (double basket strainers) are used when the flow or process cannot be shut down and must continue to flow. Duplex strainers allows you to shut one basket for cleaning while the other is still in operation. Double basket strainers are normally used where larger amounts of trash/solids need to be removed. The screen is in the shape of a basket and removed from the top of the fabricated duplex strainer. Fabricated duplex strainers can come with a blow-off connection for manual or automatic cleaning.

Duplex Strainers

A main application for duplex strainers is in fluid handling systems such as cooling water, fire lines, hydrocarbon, fuel lines, fresh water, pump suction, compressors, and lubrication systems. Strainers body can be casting or fabricated material. Always check material compatibility with the process.  Screens should be sized to meet the perforations, and mesh requirements.    

Fabricated dublex strainers gaskets, end connections, and blow-off connections, should be part of the sizing equation.
